Join Dustin Manning for an in-depth discussion in this video Contours as surface definition, part of AutoCAD Civil 3D: Topographic and Boundary Survey.
- [Instructor] As a best practice, I always encourage people…to start with points and breaklines,…as that gives us the best results for a Civil 3D surface.…But there will be times when we need to use contours…to create our surface for profile sampling and analysis.…So let's look at the best way to do that.…Here, I have two sets of contours, and I'm going to isolate…all the layers that have those contours on them.…So I'll select one from each layer, and isolate it.…
Now I will zoom out and go to my Surfaces,…right click Create Surface.…Name it EG.…And in this case, I do want to remember where this was made,…so I'm going to say it was made from contours,…just as a note to myself for later.…And then click OK.…Now I'm ready to add those contours to the surface,…so I'll expand out Surfaces,…expand out the EG and Definition,…and I'll go to the Contours section and right click.…
Click Add.…And here, we're going to take the defaults for weeding…factors and supplemental factors.…These are usually a great place to start,…
