Whenever there’s a new release of AutoCAD, with new and exotic interface improvements, it’s worth mentioning the quickest route back to the way things were: the AutoCAD Classic workspace. This workspace gets rid of new-ish interface elements such as the ribbon, depending on what version of AutoCAD you’re using. Use one of the following methods to change your workspace:
Select Workspaces from the Tools menu, then AutoCAD Classic.
Caption: Tools / Workspace menu.
Select AutoCAD Classic in the Workspace control (either upper left or lower right of drawing window).
Caption: Workspace control. Note that its location may vary according to your version of AutoCAD.
Type Wscurrent at the command line, then enter AutoCAD Classic when asked to specify a workspace.
Type CUI at the command line, then expand the Workspaces tree under Acad. Select AutoCAD Classic, then right-click and select Set Current from the shortcut menu. Then select Apply. This method lets you see all of the available workspaces.
Should you find that AutoCAD needs further adjustment, be sure to save the final result as a custom workspace. Just select Save Current As from the workspace pull-down menu.
