Hi,

 

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?

 

Thanks.

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
