AutoCAD 3D to Revit Walls?

Hello Everyone,

I am trying my best to extract surface data from AutoCAD, and Isolate it by layer from AutoCAD to switch each surface into a wall by utilizing the wall by face method, but have been having some issues in isolating surfaces based on layer. Does anyone have any ideas on how it may be obtained?

I have been trying to utilize BiMorph package to extract the layer info, but cannot seem to get what each surface layer is?

Any ideas would an amazing help. Thank you.

Sincerely,
Kevin
