Issue 2D Cad to 3D

Hi all,
I have a case that i need to covert 2D(autocad) to 3D obj to work with threejs. I dont know how to do that, if you have any ideas pls give a solutions.

Thank you so much

When using AutoCAD, it should be possible to export your model to DWG. You can then try to use 3ds Max to import the DWG file and then export to OBJ.

Thank you!
