How to change User Interface into Classic Style in AutoCAD 2015 & 16?

If you have installed AutoCAD2015, you should notice there is no more classic workspace. If you want to use the classic workspace, then you need to create the workspace by your own.

Let’s see your options how to have this “classic” workspace in AutoCAD2015.

If you have previous release of AutoCAD on your computer, you can migrate the settings. That would include your workspaces, which is saved in your CUI files.

The first time you start your AutoCAD2015, you will see this migrate custom settings dialog box. In this example below I only activate CUI files and deactivate the rest.

If you’ve already seen this dialog box before and click cancel, don’t worry. You can still access this tool from start menu. You can find it below AutoCAD2015 folder> migrate custom settings. Click “Migrate From a Previous Release”.

After you migrated the settings, then you will see the workspaces from AutoCAD2014.

If you want to rename and delete workspaces you don’t want, you can do it in CUI editor. Type CUI then enter. Right click above the workspace name to rename or delete it.
