Hi!

 

Is it possible to slice 3D objects at a specific height?

 

For example, I have a 3D model from a building, and I'd like to know what the exact outer bounds of the house are at +2m above ground level.

 

Thanks,

Mark

Hi @markvv​,

FME 2022 now supports surface clipping, so it is possible using the following method:

  • Create a 2D box well outside the 3D object to be sliced with a 2DBoxReplacer
  • Elevate the 2D box to your desired clipping elevation with a 3DForcer
  • Extrude the elevated box by a very small Z distance (ie. 1mm) with an Extruder
  • Use the resulting extrusion as a Clipper in the Clipper transformer
