I have 3D faces that I want to extrude downwards untill they reach a certain z value. This z value is different for each face and included as an attribute. The problem is: the extruder only let's me extrude downwards over a certain distance or vector, creating a solid with the same structure at the bottom as on top. However, What I need is a flat structure at the bottem, at the level of the z value. Is there a way around?
PS: I already managed to do this by creating also an exctrusion downwards for this z-value, and than clip both extrusions. Unfortunately, this method is unacceptably slow for me.
