Method or operation not implemented - FootPrintRoof

Gives a preview but not all the geometry, say ‘Method or Operation not Implemented’

They are hosted & provide a face – is there a way to get face geometry?

Thanks, sorry can’t post files on this.

Latest WIP, RiR.

There is a component called HostObject Faces that should give you top and bottom faces of the roof.
If you conect the faces outputs to any Brep param you should obtain the faces geometry as a Rhino Brep.

Could you please share those roofs to see here what needs to be fixed in Element Geometry component?

Gotcha, i was trying to get element geometry out of the host face.
