Project to 2D a Polygon Mesh

[PabloAlv]

Hi!

I need to project to 2D a 3D drawing. I often use the SOLPROF tool but my current drawing is a Polygon Mesh. 

Anyone have an idea on how to convert a Polygon Mesh to Solid? 

Thank you in advance

PS: I've attached the file.

FLATTEN command should make the projection without any need to convert..  Just make a copy and "FLATTEN" the copy as the operation will eliminate the 3D geometry it's projecting.

Thank you very much! Solved!
