Create Object ID Collection

Civil3D
1

The AddBoundaries method for civil 3d surfaces requires an object ID collection of the polyline boundaries. How can I create an object id collection in python. In my case, there will only be 1 polyline in this collection.

I’m using this example as a guide.

coll = ObjectIdCollection()
coll.Add(plineId)

What is the correct way to feed in the boundary type? I did what the Developer’s Guide example has, but it did not work.

try just Autodesk.Civil.SurfaceBoundaryType.Outer

EDIT: what are the import statements at the top of your file?

I got it to work by adding

from Autodesk.Civil import *

but without “Land”, correct?

Correct.

So, I ended up with:

surface.BoundariesDefinition.AddBoundaries(col, 100, SurfaceBoundaryType.Outer, True)
