Hello all,
I'm trying to create a surface that reflects the existence of a 6' x 6' box culvert running underneath a dirt road. This culvert is going to be ripped out and replaced.
For our design team, I'd like to be able to create a 3d object reflecting the box culvert that I can trim from the surface, so that our materials calculations will be correct.
So far I have the existing ground surface, and I've extruded a box with the base along the flowline elevs. I would like to be able to trim this box out of my surface, but SURFTRIM command is telling me I don't have valid objects.
Please let me know if you have any ideas. I'm open to different approaches. Or if I didn't explain that well, I can try again.
Thanks !
