Hello everyone, I want to know if there’s a way to create catchment area from objects with dynamo to optimize the process on my company, because here we define several catchment areas with polylines on industrial plants and after we need to transform each polyline to a catchment area with Civil 3D …

How come you don’t use scope boxes? You could select the polylines manually … Then get geometry location and check to see if the location points are inside the polylines. If you were using scope boxes or site property lines you can select them in Dynamo by name. You can’t name polylines.

Check camber package [image] Acess Catchment Group Python Civil3D Don’t know if this helps you with python, but anyone else needing to work with catchment groups checkout the Camber package: [image] [image]

Hi @rogerio.jacob , Try this node in the Camber package. [image] The boundary input requires a Dynamo polygon (or a list of them). There are various ways that you can create polygons from AutoCAD polylines. Check around the forum for some inspiration.

I believe that scope boxes are only for Revit, am I wrong? Don’t believe this will work with Civil 3D. Please, correct me if I’m wrong.

Thanks a lot! I will see this node, I think that I ignored this, I believe this will be my solution!

Ah, sorry, I need to learn to read more carefully :person_facepalming:

Hi, @mcons , Consegui fazer usa rotina , em Polyline.Vertices, selecionei, @L2. e deu certo! Obrigodo!

Hi @zachri.jensen,

When I pass a list of polygons to the boundary input the node returns multiple identical catchments in the shape of the first selected polyline. Should I be using different nodes to make this work? Thanks.
