How do I run AutoCAD 2010 with the classic User Interface?
AutoCAD 2010 continues it’s User Interface (UI) revolution since AutoCAD 2009. Many old users were uncomfortable about this dramatic new UI, and new users are to accept with pleasure with this new appearance. Is there a way for AutoCAD to look (or feel) like the older version of AutoCAD with new AutoCAD 2010’s new features? The answer is absolutely positive. Since release of AutoCAD 2006, users can begin to define their user interfaces which toolbars, menus, and palettes, command window, locate or appear at exactly according to user’s specification. Workspaces are a great concept, because users can save multiple workspaces to reduce the time that users need to create comfortable working environments. AutoCAD is installed with default workspaces, and you have the ability to create your own workspace as well. The default workspaces are 3D Modeling, 2D Drafting & Annotation, and AutoCAD Classic.
Four ways to change your current UI to AutoCAD classic:
1) Go to your Pull-Down Menu> Tools > Workspaces >AutoCAD Classic.
2) On the Workspace Switching status bar (locate at lower right hand side), click Workspace > Switching > AutoCAD Classic.
3) Enter WSCURRENT command, and then enter “AutoCAD Classic” when prompted to specify a workspace. With this method, you have to enter exactly “AutoCAD Classic” as your worksapce. This method won’t work, if you don’t know the exact name for your workspaces.
4) Enter CUI command, and a Customize User Interface widow will pop up. Right mouse click under ACAD>(you need to unfold to see all the available workspaces) AutoCAD Classic>Set Current, and don’t forget to click APPLY. A visually more complex way to get to your AutoCAD Classic UI.
