Civil 3D Corridor Mass appear Null

[WrightEngineering]

If you’re trying to generate/create solids in dynamo prior to export you will need to first have the solid geometry available in civil 3d or use Zachri’s approach below:

Extract Solids for Multiple Corridors

I know it’s not a very dynamic work flow but it sure is easier to extract/create the solids in civil 3d and then use the Corridor.GetSolids. Especially when trying to generate all of the geometry on the dynamo end, for multiple corridors at once. Seems to want to crash my dynamo instance anyway [ExtractCorridorSolidsFromDrawing]

Create solid from corridor

Hi @oh_ruki, You could skip any interaction with the API and use Dynamo to create the solids by loft from the shape codes. Notice the list levels and lacing. [ShapeCodesToSolids] [Solids]
