Civil 3d Surface Questions

Anonymous · ‎02-08-2017

Hey everyone, I'm somewhat new to civil 3d. I used it in college about 6 years ago but haven't done much with it since then. My end goal is to draw a road section and do parcel layout on a tract of land. I got the dwg file for the parcels and centerline from the GIS office. I also got the contour line shape file from them as well. I have imported the shape file, and assigned elevations to the contours so now I am ready to create a surface. What I would like to do is use the dwg file for the parcels while its overlaid on the contour map to create my surface and make my outer boundary the outer boundary of the parcel. How would I go about doing this?

Thanks!

Step #1 Call a surveyor and get a real boundary & topographic survey.

If you can't do that then do this.

Save the file as - Existing surface

Then you can create a surface (home ribbon>create ground data>surfaces>create surface) name it existing surface

It will be empty, in your prospector> expand the surfaces +, then expand existing surface > Definition

Then there is a listing for contours. Right-click on that and select add. Make sure you set your mid-ordinate distance to 0.1. Pick all of the elevated (3d) polylines.

There you have a surface, now put those polylines on a non-plotting layer and lock it. If you delete them they will erase in the surface.

Hope that helps

Add the contour data then apply the boundary
