Merge multiple surfaces

[rrichard32SXK]

Hello everyone,

I need to create a volume.  My (Comparison surface) is pretty simple, I have only one.  For my (Base Surface) I have three - Left, Center, Right.  Left and Right are at the elevation 120m and the Center is at 115m.

So, how do I merge the three surfaces that are at the Base Surface, in order to get a volume?

Attached drawing description

Comparison Surface: SURF-158-PROP-150mm-2023

Base Surface: Left and right SURF-SURELARG-1-2-3-4-5-6-7

Base Surface: center SURF-DATA-EXTRAC-PAV-EX-SURELARG-OUEST-220mm-2023

Thanks,

Roger

I would make a forth surface and past the three into it, where they overlap the last surface in governs the elevation taken. the definition tab will be handy for rearranging the order if needed

note pure vertical is not accepted in civil3d

Hi rrichard32SXK,

Absolutely right.  I need to narrow the Center Base Surface (yellow lines), from what I understand on your suggestion.

Thank you!!!

doesn't have to be great. Just enough to prevent vertical.

before you go offsetting boundaries, try it as is and see if c3d does it internally. At worst you will get an "error pasting surface" message.
