Hi all,

I have a 3D mesh in a DWG file (3D surface of a pavement) and want to convert its footprint to a single polygon in an Esri file gdb polygon feature class (for use in 2D GIS). Can ignore all attribute information. Tried following this post but without luck (I think I need more detailed instructions re settings for each transformer). Anyone here able to help me? Thank you!

Hello @lcw​ you might want to look into using the 2DForcer transformer followed by something like the HullReplacer
