I am trying find a good workflow to bring our Civil 3D surfaces into Revit via Dynamo. I am exploring using a LandXML file of a Civil 3D surface and bringing that into Dynamo, then into Revit. I used Jostein Olsen’s graph to see if that would work for me (Thank You Jostein!!) The graph seems to run fine except for the Mesh.ByPointsFaceIndices node, which comes back with the error message of:
“Warning: Mesh.ByPointsFaceIndices operation failed.
One or more IndexGroups supplied contained an out of bounds vertex index! All IndexGroup indices are zero-based and must be less than the number of vertices supplied.”
after some investigation I think I have found the problem and the IndexGroup.ByIndices two nodes upstream is showing a “D” index with values other than zero. I don’t know how to get the “D” index values to go to zero. any help would be appreciated. Thank you all for your time. I have enclosed some screen shots of what I am getting with my graph and revit model.
