Introduction to creating 3D text for beginners

Examples of creating 3D text, which can be used as Additions or Subtractions (like carving).



NOTE:
When using Deluxe or Pro with TC Surfaces, one will probably need to set the Surface option

high (60-90) to get a smooth looking result.



One of the simplest way to produce 3D text is to give 2D text a thickness, however you can’t add thickness to Standard text, but you can once the text is

changed to ‘Flexible mode’ in text properties. Select the text, then right click and choose Properties—›Text page. Change the Mode

to Flexible, then select the 3D page and add the desired thickness, alternatively use the selection properties palette to alter the Mode and Thickness.




Image


Image




This method has the advantage of allowing for further editing providing the text has not been exploded nor any boolean operations have been carried out, for

example changing the font, colour or adding underline.




Image




The text is not limited to simple colour, Materials can also be added to produce the desired effect




Image




A disadvantage of this method is that the text is a bit faceted, though in many cases this will be hardly noticeable and perfectly acceptable, this is due to the text

being based on a polyline with only line sections (no Arcs), it may only become an issue when the thickness is deep or with large scale text.




Image





Pro only ACIS There are some limitations connected with thickness text, in that one cannot use things like blend nor chamfer, for blend/chamfer the

text needs exploding down to an Acis solid, select the thickened text, check the selection palette to ensure it has not already been exploded or converted, and if

not, click the explode button twice, the first will convert it to a group, the 2nd to individual polylines,


one can explode a third time so the selection palette shows it as an Acis solid, but this is not really necessary as once the blend etc is carried out the palette will

automatically show as Acis.




Image




Another way that text is converted to an Acis solid is to perform a boolean operation for example addition or subtraction, this has the effect of by-passing the

steps above but obviously as above it is no longer editable as text,




Image





Note, setting the text to flexible is not strictly necessary, for example after exploding standard text twice to get it to a polyline, one is left with a ‘brush filled’

polyline, after which one can explode again to separate the brush from the outline (as in T), or set the brush to none (e), or simply leave it as it is and give it

thickness (x) or use the extrude tool which will leave the base polyline/brush intact for reference (small t).

Converting Text to Curves


To overcome the faceting effect of 3D text one needs to be a bit more creative, in this first example we will convert the text polylines to curves, (Note this

converts to a bezier curve - convert to polyline arcs discussed later)




Image




First a note regarding the tolerance and line settings for convert to curves, one is presented with a dialog box for tolerance and keep lines, this affects how the

resultant bezier curve is drawn, one needs to remember that the curved part of the text is basically a lot of small line segments, which means the wrong setting

can result in the bezier’s simply representing all the line segments instead of smoothing it out.




Image




The figure below uses Times Roman font, and shows some of the differences that the tolerance and keep lines settings can make when converted, converting

using too many bezier can often leave a faceted appearance, the figures are a guide only and will differ depending on the object / text.




Image




In the following example we won’t bother setting the text to flexible as we simply want the polyline with no further text editing, start by typing the desired text,

explode it twice and set the brush to none.



Now there is one extra thing we need to do, many letters contain ‘a hole’ but TC is still classing the whole object as a single polyline, if these are left as-is it can

cause problems.



The ‘e’ below was left whole and simply converted to curves, as one can see below TC has treated it as a single polyline and joined the hole to the outline,

which isn’t desirable as can be seen when extruded


To get round this is very simple, select all the letters with a hole, (a, b, d, e etc) and explode one more tine, this will separate them into two separate polylines.




Image




The next step is to convert all the polylines to curves, unfortunately TC doesn’t seem to be able to convert them all at once, so just select each letter or hole one

at a time and click the convert to curves button, experiment with the tolerance and the ‘keep lines’ settings which in my opinion should be a compromise between

accuracy and ease of editing, some fonts line Arial may not need the ‘keep lines’ box ticked, but experiment and use the edit tool (select polyline, right click and

choose edit tool, or select the edit tool button).

Keep in mind that the exploded text consists of multiple polylines, so setting the line segments too small e.g. 0.001 could produce a lot of bezier segments and it

may seem can still leave flat segments,




Image




After converting all the polylines to curves it may be necessary to do some minor editing on the bezier nodes to smooth out some curves, select node edit mode

and adjust either the main node (blue), or the node handles (green).




Image




Once one is happy with the shapes, one just need to give it a height which can be done just as any other 2D profile object, for example set a thickness, or I prefer to use the 3D extrude tool, or a duplicate copy set at a ‘Z’ height and the two or more profiles lofted which can be useful to unusual text effects as below.




Image




Converting to polyline arcs

(from v19.1) Not Known at time of writing if this is Pro only




Image




If your version contains this tool, it is a good alternative to convert to curves, as it converts the text profile to a series of lines and arcs, the process is similar to

convert to curves previously discussed though the dialog box has two more options.




Image




The ‘keep sharp corners’ does what it says, it will attempt to keep the corner as a polyline rather than change it to arcs, it really depends on the font as to how

useful it is in any situation, if it is not set then converting can result in some shallow corners being converted to an arc (as in (1) below, in order to keep the area

marked sharp, the keep corners was ticked and set to 140 (2), however this causes other problem by converting some which are meant to be arcs into line (3)




Image




Therefore a compromise will have to be made if your font requires this option to be selected, The last option (keep origin) makes a copy in place and converts

the copy to lines/arcs, which can be useful in comparing the converted object with the original, simply give the copy a different colour to make it easy to see how

accurate the copy is.


Please note:
The same rules apply as with convert to curves with regards exploding letters with a hole,

and also creating 3D from the profile using thickness, extrusion, lofting etc.



The minor deviations mentioned above will mostly be irrelevant, unless one is dealing with very large text, the example below uses the default values and is a

pretty good representation of the text, zooming in a lot shows one tiny segment that was converted to line instead of arc, which in reality will be un-noticeable.




Image




As can be seen below, the results of using arcs (or even curves) are superior on the bends than polylines, 1 = original polyline text, 2 = concert to curves




Image




However like a lot of things there are drawbacks, unlike curves, Arcs don’t like being scaled in one direction only,

As can be see below, enlarging in the x axes only produces distortion




Image

Drawing letters


The next example involves drawing the letters from scratch using text as a template,

Arcs



Arcs and lines have an advantage in that can be joined to produce a single polyline using the join polyline tool,
A disadvantage comes when scaling, lines/arcs can go wrong if scaled in one direction only, as this can change the shape dramatically (exaggerated below).




Image




—
Pro only
also adjusting arc nodes after the profile is created may give problems if the object is to be blended (Pro only).

it must be stressed that in most cases it would not cause any problem at all, but very occasionally it can cause problems with blending the edge, the picture

below may explain better, in (1) below the S is drawn as continuous polyline arcs, in (2) it was altered very slightly at the point marked by the arrow, and still

looks fine.




Image




The profiles were then extruded and the top edge selected for blending with the ‘round vertex’ option selected, with (1a) a single click selects all the top curve

edge up to the line section shown by the red markers, this shows that all the curves are tangential to each other to produce a smooth blend.
In (2a) selecting for blending won’t select all the top edges requiring 3 clicks needed to select all the top edges, also when all edged are selected one can see

the green markers on vertical lines this suggests that the curvature is not perfectly smooth, and this is what is meant when the write refers to kinks.




Image




In the unusual lofted example below the ‘S’ profiles were copied, scaled (always scale arcs the same in both direction) and lofted, the top edges were then

blended, a close up on 2b shows a flaw where the original profile was altered, and when it came to chamfering, 2c could not handle the same offest length as

1c, but halving the offset allowed it to chamfer, a close up still shows the flaw, there was no problem with 1b and 1c which were not altered.




Image





Splines


mostly pro only depending on text shape)


Splines lend themselves very well to 3D text providing ones version of TC has a compound profile button when extruding, splines normally produces very

clean lines, which are normally easy to blend or chamfer (Pro only), they are easily edited and scale well in either direction.




Image




Disadvantages, - often requires the compound profile tool and should not be used with the join polyline tool, as this will convert the spline to loads of small

polyline segments.

It is sometime not a good idea to put two spline curves end to end as it is not always easy to ensure a smooth transition, the same can apply between splines to

lines, a possible solution is - in spline properties having ‘show frame’ ticked allows one to align the ends more accurately




Image




To draw them, put the text on a new layer so it can be easily hidden, as with arcs start with the text as a template, select spline by fit points and use ‘v’ and ‘n’

snaps to trace the text, editing the spline in edit mode will often be required, switching between fit point and control point mode as necessary, for the straight

sections use polylines or single lines as appropriate,




Image




Once drawn, hide the text layer, select the extrude tool (unless one wishes some lofting effect), activate the compound profile option, select the profile and set the

desired height.




Image




Bezier


Bezier’s are similar to splines but they have the advantage in that they can have multiple sharp edges (splines can have a knot (sharp edge), but can be more

difficult to control), they can also be used to create a single profile with simulated lines / curves (as produced using convert to curves) and thus may not need

the compounds profile option.
Disadvantage - as with splines they should not be joined using the join polyline tool, They can seem complicated when editing (in node editing mode) if too

many nodes have been added, as each node has two handles plus the nodes can set using various options (equal curve, nonequal and non smooth),

however this is not the place to discuss the individual editing of Beziers so I’ll skip that bit.

As with splines and arcs, simply trace over the text template either as a single object or with beziers and lines, for use with the compound profile option,

_The next subject is carving.__


Carving in this context is producing a channel whether a ‘V’, ‘U’ or other shape by using the sweep / rail sweep tool,




Image




For this one just needs a centre-line of the text, to ensure reasonable accuracy I would suggest using lines, rectangles or circle by two points on the exploded

text template to give snap points for the centre-line, the pic below was done for both outline and centre-line with the red lines as snap points to draw the centre-

line




Image




An alternative is to use SHX fonts which often just polylines, in the figure below the bottom text is SHX, and the top is a traced polyline using arcs which will

readily allow for a profile to be swept along to produce a pattern which can be subtracted to give a carved effect.




Image




When preparing text for sweeping, one should remember that in many cases the text (profile) cannot be a single object, for example in A above cannot sweep

along the two vertical line and the horizontal line at the same time, therefore the profile should consist of multiple lines / arcs / spline / beziers etc. as required.

After producing the centre-lines its then a matter of choosing the profile, placing the profiles in position and using the appropriate tool to sweep, in the example

below a triangle profile (green) was positioned for the sweep (ignore the outline), other triangles were placed, angled (optional) and scaled ready for lofting /

prism, the resultant objects are subtracted from a box.

Curved Text

Curved text onto flat surface


The first simple curved text is manually positioned which works fine for Deluxe and Pro, this can either be done by ‘eye’, or the angles calculated depending on how critical the spacing is, once in position simply extrude or give thickness.




Image



For TC pro users the text can be bent using the bend sheet tool, the text should be sized to match the reference arc length however consideration must be given to where it will be bent as this will vary depending on the text, in this example the centre of the text is ‘o’, therefore it doesn’t have a flat area needed to bend.




Image



Here the ‘d’ has a flat area so this can be used as the bend point, as with any bend one needs a bend line shown green. If no suitable flat area is available then one would need to temporarily ‘add’ a box, which can be removed later by subtracting a slightly larger box.




Image



The bend was then carried out using radius 14 mm (radius of arc) and angle 120 degrees,




Image





Other methods (discussed later) include graphic along path for mono-spaced fonts, and the to path tool (new in v2016),
One thing not discussed at present is the add-on menu - special tools - text along curve, this is due to it being non-operational on the testers computer at the time of writing.




Text onto Curved surface

The most simple method is to extrude (or thickness) text into 3D to create the curved text, so although this method has its problems we’ll start with that.




In (1) below the text is extruded or given thickness as previously discussed, the curved object is just a cylinder cut in half with a smaller cylinder subtracted,

now it needs something to intersect with, so another half cylinder if produced, with its thickness the same as the thickness of the text required (red item in (2)

below), the text was moved so it is fully through the red item.




Image




The next procedure is to intersect the text with the red object, note if the text has been exploded into separate letters then select the red object and create copies

in place equal to the number of letters, (3) below shows the result (note text has not been added to the base object), the reason I said at the start that this causes

problems can be seen in (4), if selected for blending there are a large amount of nodes that have to be considered due to the original text being a polyline.




Image




To get round this problem it is better to create the text with curves or arcs using convert to curves / arcs or drawing from scratch as discussed previously, this

will provide clean edges and allow blending easier as shown below, (the text below was converted to curves).





Image




The next problem with this method is the shape of the text, the picture below show how the text appears after intersecting because of the curved surface the text

is elongated on the curve, on large curved surface or small text this may be acceptable and almost un-noticeable, but where it becomes a problem a different

approach is needed.




Image




There are numerous ways of achieving the same result, here is just one method, the basic approach is to angle the text so it points towards the centre of the

curved surface, start with the text reasonably close to the required intersect object (in red below), and vertical ‘dotted’ line drawn from the centre of the text.
From this move the letter closer to the object as below.




Image




The for this exercise a circle was drawn where the inside of the text would be, and also boxes were drawn the width between each of the original text

characters, these were then angled towards the centre of the circle for guidance.




Image




Next the text / curves were moved to just inside the circle and angled towards the centre on the circle using the boxes as a guide to the distance apart




Image




The curves / text were the extruded (with compound profile turned on) so that they will be proud of the intersect object (in red), when extruding the ’e’ select the

outer curve, hold down the shift key and click the ‘hole’ curve, this should extrude it as a single object without needing the hole subtracting.




Image




In the picture below one can see that this method doesn’t elongate the text as it does by simply extruding the flat text (shown in red)




Image




Image




Graphic on path

One procedure which in certain circumstances would be viable is to use the Graphic on Path tool, however it has drawbacks in that it only really works on specific text.
The theory is to produce a single letter, which is then replicated using the tool, which creates copies (sets) along a curve / arc path, the path should be minimum diameter required, then using selection palette, each letter is simply changed to the required one.




Image

Image



The profile (letter) will be copied along the path by its ‘z’ axes, this means the text is rotated and requires each letter rotating back by 90 degrees, the main problem using this method with many fonts is that the letters are not equally spaced, so when using this tool the letters will appear badly spaced. spaced, as in the Arial font below.




Image



Where this is a viable solution is with mono-spaced fonts like ‘Courier’, this text lends itself perfectly to getting the text nicely spaced, and by rotating back 90 degrees the text if aligned for extrusion.


To use this method for example on the word TurboCad, first select the path (in this case an arc) and read its length in the selection palette (20.4 mm), divide this figure by the number of spaces (7 = 2.914), type in the first letter ‘T’, select the graphic along path tool, select the letter, on the inspection bar type in the number of sets (8), in the distance type in 2.91, activate the button ‘set start point’, and click the line.




Select each letter in turn, rotate by 90 degrees and change the letter using selection property palette - general - Info, and finally give each letter a thickness.




Image



Image



The actual order in which the above can be carried out is variable and down to personal preference.


As previously stated there are many ways of achieving similar results, there is no right or wrong way, whatever procedure you gaet to work is the right one for you

Curved Text by Bending

(if supported by version)


Another method of text on a curve is to bend the text, for this example we will use thickness on flexible text around a can, the question is how large to make the

text, bending text changes obviously changes the way one looks at the can, as can be seen on the pic below the red is before bending, blue after.




Image




Therefore one needs to decide the size of the finished (bent) text before attempting the bend.



The process is similar to any other bend, Type in the text using the appropriate font, and size (or resize after) open the text properties and set the text to

Flexible, give it a required thickness, Below is Arial Bold set to Flexible and 0.1 thickness.



Image




As can be seen part of the letter ‘o’ is on the centre line so in this instance I will draw a line on the back face of the ‘o’ and bend both ways around that, in no flat

face then a different bend type needs to be used, whilst individual letters will bend, I don’t know a way to bend actual words, therefore before bending the text is

exploded twice to polylines, and the all letters added together, this effectively changes the text to ACIS solid.



The bend is then carried out the same as any other bend with the radius set the same as the cylinder radius.

Image




The text will fit nicely on the surface of the cylinder, NOTE - if the text is to be subtracted from the cylinder, this will need to be taken into account preferably

before bending,



Image




Curve text Bend by Path (from TC v2016)

Introduced in TC v2016 is the bend to path tool which will bend an object based on an open profile i.e. arc, curve etc, however one thing to bear in mind is that

it will resize the object to fit the profile, therefore it is necessary to set the correct arc or curve length and text size to avoid stretching the text, in this example we

will use an arc.



In the pic below, No.1 is the original text and No.3 is the arc, as can be seen in the No.2 when bent the text is stretched to fit the arc, This may be OK in some

circumstances but some text will not lend itself well to this stretching, in No. 4 the text is resized correctly befor bending and maintains the aspect ratio much

better.



Image




To get the correct sizes, either draw the arc etc. and read the length in the selection palette - properties - Metrics section, or calculate the arc angle, for example

in this case the length of text 5.857935, circumference of cylinder 47.12389, therefore 5.857935 / 47.12389 x 360 = 44.751327 degrees, therefore use this to

draw the correct sized arc.



Refer to the help file or Wiki for full use of the bend by path tool, but one main thing to remember with text is that after selecting text the first axes line must be the

full length of the text, for example with the word ‘Turbo’ there isn’t a direct horizontal line for the full length of the text.



Image




One of the simplest ways to get the correct snapping point is to draw a rectangle around the text which gives perfectly horizontal points for the correct

alignment.



To bend the text, one way is outlined in the pic below,



Image




The result in nicely ben text at the correct scale and aspect.

Curved Text Projection.

Projection is one of those things which in theory should be a viable solution, but in practice it takes more work and can be disappointing,
As can be seen on the projection page of the wiki Intersection and Projection the projection produces polylines and splines (2D and 3D) onto the face of a solid object (can be a sheet object),




Text itself cannot be used at a projection, it must be exploded down to a a polyline or two polylines if the letter contains a ‘hole’ (A, B, D, etc.), if when trying to select the letter for projection one gets an error sound (for example ‘dong’), it normally means it isn’t exploded down far enough, keep and eye on the selection palette, even when it says Polyline, it may require one ore explosion - but not as far as being a load of lines.


Image




There is one important point about projection onto a curved object, the result will likely be multiple 3D splines, and although the compound profile will work with for example extrude and loft, the result is often a sheet object which requires a more work in order to try and get a solid object.




Image




As extrude often fails to produce adequate results whenn projected onto curves, In this example we will use loft, therefore we have created two extra cylinders to project the text onto, (Red and Blue in the attached), whilst one can project onto the original cylinder this will be insufficient if the text is to be eventually subtracted.




Image




Select the projection tool, and project each letter onto one of the cylinders at a time, hiding the cylinder not being used (this prevents errors)




Image




Hide the original (flat) text, loft each letter ignoring the ‘holes’ for now to avoid any possible self intersecting errors later on, then 3D add all the letter together,




Image




NOTE - we need flat surfaces to create a solid, so before adding together the letter could be sliced front and back before adding but here we will subtract a polyline to get the same effect.




Two polylines are drawn so that each line effectively slices a letter when extruded and subtracted,




Image
Image




Once subtracted, select the ‘text’ and choose create solid from surface tool, if all goes well the results are as shown below.




Image
Image




The next step is to reproduce the procedure using the ‘holes’, not forgetting we need flat surfaces front and back to complete the convert to solid, one could ask why not do the holes earlier - that is a valid statement and it could have been done, I chose to do it this way simply to avoid any possibility of errors or self intersecting, whenever the holes are completed is fine - whatever works for you,




Image




If one receives this error when converting to solid, it likely means that the ends were not perfectly flat, retracing ones steps normally will solve the problem.




Image




The result can be added, subtracted or intersected depending on ones requirements.




Image




Drawback - apart from the extra work required, the main drawback is that when the text is projected it is done as-is, in that the original flat letters are not rotated before projection, so each letter can become distorted (narrower than the should be).




One can try to remedy by angling each letter towards the centre of the cylinder, but that brings a second problem of keeping the letter spacing when projected.

Text on a multiple curve


Up to now we have concentrated on flat text and text around a cylinder, but what about multi-directional curved text.




For the first example we will use the object below and wrap the text around the edge using purely a manual method of positioning the text which will work with TC Deluxe.




Image




A quick note one the setup, the 3D selector has been set to Extents = Entity, to make it easy to rotate and snap the numbers




Image




The image below shows the object (blue), an arc which the text will be centred on (green), and a red line which will be used as a snap point for the letters.




Image




The line is then radial fit copied, 9 sets, 180 degree angle, and the letters are then snapped to the intersection of the lines and arc.




Image




The numbers are obviously orientated incorrect so rotate the numbers correctly to point at the centre, in this case multiples of 22.5 degrees.




Image




The numbers are then rotated verticaly using the line as a snap point, the angle could be derived and typed in, but snapping is much quicker.




Image




The result is obviously flat numbers on a curved surface, but from here one can manipulate the numbers in whatever way is required,.




Image




In the picture below, two closed polylines were revolved, the numbers added together, and the revolves subtracted from the numbers, leaving nicely curved numbers.




Image




This method simply shows that using 2D as a basis for 3D objects can really help with set-up, and allows things to be accomplished in TC Deluxe where tools like ‘Bend’ are not available.




The second example used the Bend tool on pro versions, file and description courtesy of John R (see quotes)




Whilst the previous example involved setting up the 2D into the correct ‘bent’ orientation first, this example bends the 3D numbers into the correct orientation.




The first thing is to design the 2d which will be used, the ‘marks’ can be simple 2d rectangles ir drawn with lines & arcs, the numbers can be whatever one requires, thickened flexible text, left as polylines (from exploded text), converted to arcs or curves, or drawn from scratch, its just personal preference.




“The text length I got from the construction arc; 4.03623 inches as a circle and 2.69082 inches for the Arc Length. I used single lines at first for the markings and used Distribute by Distance to space them out evenly. I replaced them with extrude-able lines-n-arcs later. It's so much easier to lay it all out in a straight line”.




Image




For the 3D everything can either be extruded or given thickness depending on how things are drawn, an advantage of the extrude tool is that it can be used with the compound profile option, thickness will only really work satisfactory on closed 2D, therefore in may cases thickness would not be an option. Note the box on the far left hand side is sacreficial and used in the bending process,




Image




“The "Text" (lines-n-arcs) and markings were extruded all at once, but they could be extruded in smaller/manageable groups, then 3D Added into one complete object. To extrude all at once, insert a Height first, then lock it (Ctrl+L). Once everything is selected, release the Shift key and wait for cursor to stop spinning. When you get the program back, Tab into the Height and hit Enter. If you had to enter the numbers, TC would recalculate after each numeral.”




Before using the bend tool it is necessary to angle the text to the same andle as the surface it will finish up on, in this case 15 degrees.




Image




The next step is to bend the object but we need a flat surface to do that, therefore a small Box is added to the sacrificial part so that it gives the object a vertical flat surface to bend, then add a bend line.




Image




Bend as follows,
“To Bend the text, I used "0.642386 in" as a Radius (the size of the inner construction arc) with an Angle of 360° and turned off the "Left side" option. When the text initially bends, it inserts a "Neutral Depth" value, but it doesn't bend correctly. With "Neutral Radius" set to "0" (bottom of the text), the bend preview shifts and the text moves to where I think it should be.”




Image




After placing the new (bent) object into place, draw a box / sphere or whatever around the sacrificial part and subtract to remove it, the last decision is what to do with the object, addition, subtraction or a combination of intersection/subtraction.


“Doing this two-part subtract/intersect method pretty much guarantees that the letters, or whatever, are nice and smooth with the target object; be it flat or curved”




Thanks to John.




Image




The same approach as above can also be applied to a sphere with a few variations, a sphere doesn’t have a fixed angle, therefore the bend angle should be an average (centre) of where the text will finish up, OK, probably didn’t explain that properly, so to an example.




The first thing is deciding on the text height and the average bend dimension, as shown, selection palette reports arc length of 177.55, so the text size should be set at 177.5 mm x 40 mm.




Image




The angle of the box can simply be read from the inspection bar.
Once all this information is known one simply carries out the bending as in the previous exercise.


To get text following the sphere shape, one can draw two more spheres - for the inner and outer




Unusual ways to get 3D text,




Face to Face lofting.
Not a normal way, the theory is quite simple, extruded (or thickened) text is set up as flat text, EXCEPT do not subtract the holes, as it can cause problems later, it is then copied smaller (for example 0.2%) and placed near the centre of the sphere.




Image




Activate the face to face lofting tool and loft between like characters, BUT, don’t loft the holes yet, then 3D boolean add the letters together.




Image




Create two spheres to intersect with the text, subtract smaller on from larger one, then 3D boolean intersect with the text, face to face the holes and subtract from the text, the result is 3D text angled towards the centre of the sphere.




Image




Sweep




For this one, 2D text is placed in position in front of the sphere,




Image




A spline (or arc) is drawn from a letter to the centre of the sphere, using ‘E’ seke to snap to a letter, if it doesn’t snap properly first time it no problem, simply snap to the letter afterwards and adjust nodes as necessary.




Image




The spline / arc is then copied and snapped using ‘E’ seke to each letter, and rotated towards the centre of the sphere, these will be the paths for the letters to follow.




Image




The letters are swept along the paths, the holes can either be swept separately or with the letters using compound profile option.




Image




The last stage is the same as previously, create shperes, subtract / intersect to reveal the letters




Image




One method not discussed with regards to a sphere is projection, whilst projection is normally onto a surface, it also works from inside a sphere to the outside, in the picture the text is small and near the centre of the sphere, its position is lined up (green lines) so the projection is performed from the centre of the sphere onto the red circle which is drawn on the sphere face.

This type of projection is easier to get accurate than projecting from the outside, in this instance two projections are made onto different sized spheres ready for lofting..




It does present the same problem as discussed earlier in that the resultant loft will be a sheet object and the only real ways to convert to solid is to either slice each letter twice, or subtract a box from the front and back, to create two flat surfaces for the solid from surface tool to work, all this extra work may make this method unrealistic..

Conclusion.


Basically use whatever method you feel comfortable with and that suits your needs, feel free make up your own method, each method has its plus and minus points but TC allows the option of choosing the method which will produce your desired effect, have fun and experiment.




The End
