I have prepared some drawings in Autocad2008 and sent it to an engineer. One of the engineer is able to open my DWG drawings in eDrawing viewer or with AutoCAD 2013 LT Trial without an error but another, however another engineer who tried to open the drawings in Autocad Mechanical 2012 and he was getting an error "93 errors were found in the drawing file during open. Would you like to cancel this open?" and in the bottom most pane it is showing warning as "Entity type is mapped to non configurable layer".
Now after some R&D we found that we provided drawing files made via the Architecture version of AutoCAD and not the Mechanical version. And now we need to change the profile setup in the Architecture version to the vanilla version and save the file as AutoCAD 2010.
Please let me know how can i change the profile setup in the Architecture version to the vanilla version in Autocad2008.
