+8We have digitized some roofs with dormers.
Now during the creation process the dormers were digitized into the main roof to avoid gaps. Unfortnatley there were no snapping used.
For example:
Is there a way in fme to cut these roof polygons from dormers which are inside the main roof (blue line)?

Hi @limo,
In FME 2022 and up, you can use an Extruder transformer to extrude the roof polygons into solids. Set the Direction to Vertical and the Distance to the negative of the Z range of the polygon. Use the resulting extrusions to clip the roof polygons with a Clipper.
