Hi there. I m working in autoCAD'13. I have got this drawing from a client. I need to trim these surfaces to get only the outer surfaces. But since these are not intersecting at right angles, i m not able to trim these surfaces. 

Any help will be highly appreciated.

Please find uploads/385607/Test.dwg" rel="nofollow - attached a small part of the concerned drawing. The intersecting surfaces in the drawing have to be trimmed.

Sorry, must have missed that subtle color change in your first post.

Hello rohit.jain092, I don't know precisely what you want to do with your surfaces and as when you select them, no grips are available but with an UCS seting ( option 3 points to have the good direction ) I was able to "trim" them with the command SUBTRACT by copying a surface and then subtract it to itself ( with a certain distance otherwise you erase it entirely ).
Hope this will help.
Ask for more.
