Hey,
thank you very much for the quick answer. With your suggestion I managed to get my case running. What helped:
– The WFs work fine with multiple cuboids as long as they cut the walls perpendicularly
– The WFs do not seem to work when they cut a wall at a non-perpendicular angle. This can be remedied by setting the samplingCellDistance to a small value or disabling it. Then no sampling outside a particular cuboid is done. I am not sure which impact this has on the performance of the WFs.
Feel free to let me know if I got something wrong.
