nyaromulo Posted August 11, 2009 Share Posted August 11, 2009 Hello all How could I separate contours from a surface. I want to pick each contours separately for editing. At the moment Contours are attached together-as-one! thanks Jackie Quote Link to comment Share on other sites More sharing options...
Hardney Posted August 11, 2009 Share Posted August 11, 2009 Quickly, I would say, make a copy of you surface and explode the copied surface you should have your contours on whatever layers they are on individually. It might take a lot of space though. Quote Link to comment Share on other sites More sharing options...
Danse_Macabre Posted August 11, 2009 Share Posted August 11, 2009 What about the contours do you want to edit? You might be able to acheive what you want to do using breaklines or something like that? I am always extremely hesitant about exploding things, as was said above it will make your drawing bigger and will make it less convenient to use.

BIGAL Posted August 12, 2009 Share Posted August 12, 2009 You can export out the contour lines they become polylines Surfaces utilities extract objects from surface Quote Link to comment Share on other sites More sharing options...
sinc Posted August 13, 2009 Share Posted August 13, 2009 The general concept in Civil 3D is you don't edit the contours, you edit the surface definition. You CAN extract contours from a surface, then simply change the contours. But if you simply change the contours without changing the underlying surface, you impact all the other things that you can do with a well-built surface, such as calculating volumes, creating profiles, etc. Quote Link to comment Share on other sites More sharing options...

I know different software need contour or 3d faces but that all can be extracted from the surface to be used as a stand alone dwg. my 2 cent.
