chizifreshi Posted January 29, 2012 Share Posted January 29, 2012 Hi all, I have a drawing from a surveyor showing contours which have been formed by 2D polylines. I have tried to trim out a portion of the contours, which i don't need, using extrim command but it doesn't trim any of the contour lines. Even with just the trim command i cannot trim them. i have tied exploding but still not managed to trim. Could someone kindly advice me on how to trim these unwanted contour lines Quote Link to comment Share on other sites More sharing options...

eldon Posted January 29, 2012 Share Posted January 29, 2012 What are you selecting for the cutting edge? The command line should give you a clue as to what is not happening. Perhaps you could try the command Break Quote Link to comment Share on other sites More sharing options...
BIGAL Posted January 30, 2012 Share Posted January 30, 2012 Sounds like their proxy objects you may not be able to trim them if created in civil3d then ask for the contours to be created as plines these you can trim. Quote Link to comment Share on other sites More sharing options...
chizifreshi Posted January 30, 2012 Author Share Posted January 30, 2012 Thanks for your help guys. Atleast for now break command works. i will follow up with the surveyor on the software he uses to generate his contours. Quote Link to comment Share on other sites More sharing options...
