TurboCAD 2017 Left "Drawing Tools" Toolbar is missing and I cannot find it anywhere. I have searched TurboCAD as well as Google AND this forum and can find nothing. It is as if I am the only person who has lost that ONE single toolbar.

Go to View>Toolbars.

That was the very first thing I did. It isn't there. As I said, I can't find it anywhere.

Go to the "Options" page of the "Customize" dialog and click on the "Default" button. That will reset the tools/menus to the way they were when the program was initially installed.
The configurations "tc_1024x768pro" and "tc_1280x1024pro" are also similar, in that they have a "Left" toolbar.
The "tc_1024x768pro_classic" doesn't have a "Left" toolbar; in there it is called the "Drawing Tools" toolbar. This is the original way that TurboCAD was laid out for 15/20 years.

If you select a configuration from the "Load From" list, click on the "Load From" button to load it.
