Creating Space on the Ramp
Following the issue discussed in
https://community.osarch.org/discussion/3259/how-can-i-model-a-ramp-between-walls-with-varying-height-in-blender-bonsai#latest
,
I would like to create IfcSpace elements above and below the generated ramp.
To do this, I need to create a wedge-like geometry. However, unlike a regular wedge, the bottom surface of this geometry is not smooth.
Do you have any suggestions on how to handle this?

See my last comment about using booleans to carve the sides of your irregular channel on the other thread. Same principle to create your IfcSpaces. Just duplicate the ramp and solidfy it in the desired direction enough, then boolean it with the channel object. This will give the IfcSpaces you need.
