Is there a node for creating circles in civil3d? I am using the “Circle.ByCenterPointRadius” to define my circle but don’t see to get these dynamo objects into civil3d. Any help would be appreciated.

After you’ve created the circle in Dynamo, just use an _Object.ByGeometry_ node to send it to Civil 3D.

@zachri.jensen So I have tried that but get a warning. Not sure if it is me not knowing how to use the block portion correctly but it appears that passing circle is part of the issues as well?

You’re close! I’m assuming you want to add the circle to model space, so that would be the “block” input. There’s a node under the Document shelf in the library called _Document.ModelSpace_.

@hosneyalaa @zachri.jensen Thank you very much! Everything works great once I pass the modelspace in and now I know that _Object.ByGeometry_ accepts circle without issue. Thank you your help.
