I have many surfaces overlapping and I want to create one surface with the lowest elevation for each x,y coordinate from the existing surfaces. Does autocad civil 3D have a command who can help me?

This sounds like Dejavu all overagain.


If you make volmume surfaces you can extract the zero contours to use as boudaries to the lower surfaces. I would expect to see a jigsaw puzzle that dovetails together. The make a new surface"combined and paste all the "Cut" areas into combined.

Thank you

Yes like that post...... which I watch every day in hopes of a better way.


It is very tedious work if you have a lot of survey and surface information.

Should be done congruently with the survey
