AutoCAD Civil 3D

[#1]

Hey,  I'm trying to combine two surfaces to make one.  I saw lots of people saying create new surface and paste the two in the new surface.  Is there a way to create a copy besides doing the copy base, because that keeps causing my AutoCAD to error.  

Thanks!

Create new surface, and under the Definitions, right click on Edits for the new surface is paste surface. Select the surfaces you want to paste.

You don't use Copy to paste surfaces into a new surface. Instead, create a surface, expand the sutrface in Prospector, go to Edits, right-click, select Paste Surface, here you be able to select the surface to paste.

Why do you need a copy? pasting the surfaces uses the data from the originals and maintains a dynamic connnection.

Pasting A & B into C. If A or B change C will see that change. If you make copies I dont think changes to A will be reflected in A copy
