Hi @durasovartyom ,
Thank you for sharing your sample dwg and dyn file. I agree with @keith.sowinski, Need to have a solid created from a corridor before using the Corridor.GetSolids node.
The workflow should be something similar to the attached animated gif.
- Create solid in Civil 3D from Corridor
- Update Dynamo and detach and re-attach Document.Current just to make sure it will update.
- Once you have the solid simply add object.geometry to convert C3D Corr Solid to Dyn Solid.
Cheers,
Jowenn
