In Version 18.0, several DoubleCAD tools were introduced into TurboCAD. There are 5 drawing tools found under the

**Draw**command, 3 modifying tools under the

**Modify**command and 7

**Construction**tools that are basically duplicates of many of the original TurboCAD Construction tools. There is no toolbar for these tools in the Classic UI, but one can easily be created.

In version 18.1 they broke these tools up; the Pro editions got the Draw tools, while Deluxe and Designer got the Modify tools. The Construction tools are found in all editions.

In the version 20 Pro editions, they added back the Modify tools and dropped the Box tool.

They also added

**Circle**,

**Arc**and

**Ellipse**tools to the

**Draw**Command Category. The Help file state that these tools should only be available in

**LTE Workspace**style (Pro editions), but they are found in the

**Default Workspace**style.
