The AutoCAD Classic workspace is not available in AutoCAD 2015

Apr 13, 2014

Issue:
You would like to use the AutoCAD Classic workspace in AutoCAD 2015, which is no longer available.

Causes:
The classic workspace was voluntarily removed from AutoCAD 2015 as a natural evolution towards a modern and more efficient interface.

Solution:
Toolbars still exist and a classic workspace can be created:
1. Open the Customize User Interface dialog box (or type the command CUI).
2. Select the desired workspace or create a new one.
3. Use the plus symbol to open the Toolbars tree in the left window.
4. Drag the toolbars you want to the toolbars tree in the right window.
5. Click Apply and then click OK to close the configuration editor.

See: Toolbars and Workspaces in AutoCAD 2015 (video).
The classic workspace can be imported from a previous version:
1. In the Ribbon - Manage Tab, click "Import" (or type command CUIIMPORT).
2. In the customization editor, click the Transfer Tab. The current configuraton file is in the right pane.
3. In the left pane, load the configuration file (acad.cuix) from AutoCAD 2014 or an earlier version.
4. Under the workspace list in the left pane, drag and drop "AutoCAD Classic" to the workspace list in the right pane.
5. Click Apply and then click OK to close the configuration editor.

To clean and repair an AutoCAD drawing

http://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/How-to-clean-and-repair-AutoCAD-drawings.html

To clean and repair a drawing, follow these commands in AutoCAD: 1. Use RECOVER to open the drawing.
2. Unlock, thaw, and unhide all layers.
3. XREF and remove all attachments.
4. Select all and then OVERKILL.
5. DGNPURGE (not for AutoCAD LT):
DGN Hotfix for 2013/2014
DGN Hotfix for AutoCAD 2012
6. -PURGE All * N
7. -PURGE RegApps * N
8. -SCALELISTEDIT Reset Y E
9. Use FILTERS to delete all layer filters (must manually delete them in AutoCAD LT).
10. AUDIT Y
11. SAVEAS to save a new file or save over top of itself.

Additional ways to clean and repair a drawing are:
1. Use WBLOCK to save the entire drawing to a new file.
2. If 3D elements are present, use BREP to clear their object history.
3. Save the drawing to DXF format and then reopen and resave to DWG.
4. Use AECTOACAD to save a new copy of the drawing.
5. INSERT the drawing into a new file and then EXPLODE the block.
6. Use DGNEXPORT to export to DGN format and then DGNIMPORT to bring back to DWG.
7. Attach the file as an xref to a new drawing and then BIND the xref.
8. Save to an older DWG format, open in an older AutoCAD and then SAVEAS the drawing.
