Hey all, we're planning to migrate servers around Monday, so there will be a bit of downtime :) I can be contacted at dion@thinkmoult.com for anything urgent.

Exporting IfcSpace footprint from Blender

I would need to export the footprint of selected IfcSpaces into a textfile containing a series of vertexes (x and y) in a clockwise order together with height and z and wonder how to do this in simple way? Right now I use series of python scripts in Blender but I suspect there are much more efficient methods since the data is structured from the beginning.

  • Have you tried using the ifcopenshell.geom and many other utilities here here?

  • If you're lucky and the IfcSpace is already defined from a 2D extruded profile, you can do ifcopenshell.util.shape.get_profiles(space) which will get you all the 2D profiles.

    If the IfcSpace is defined as a mesh-like geometry, you will need to use the geometry iterator and the utilities in util.shape to derive the bottom plane and the polyline itself and sort the clockwise yourself.

    Thanks, that worked surprisingly well. I also need to find representing points for vertical windows, one lower corner and one opposite upper corner and wonder if there is a similar command for this?
