re: Saving your Workspace in the Themes' UI.
Go to "Tools / Customize â€” Options page"
Overwrite a name in the "Save In" list with your custom name.
This will not affect the overwritten Workspace, you're just adding a name to the list.
Click on the "Save In" button.
You have now saved your Workspace.
The lists only show the Names, but no extensions. If you go the Config folder (C:\Users\John R\Documents\TurboCAD 17\Config
in my 'puter), you will find your Workspace saved in two files; same name, different extensions. One is a XCFG file and the other in an XML file. If you were working the Standard UI (Tools / UI Themes), then you would get just a single CFG file when saving. The Standard UI will not show Themes' UI Workspace names, as they're not compatible. Old will work in New, but not the other way around.
To "load" your Workspace, select your custom name from the "Load From" list, then click on the "Load From" button.
There should be enough here to keep you confused.
