The feature that the tool creates automatically the topmost stair unit is a great feature (as these are usually not modeled as spaces in the IFC).
But there's a thing, that might be a side effect. If there are small stairs or steps not transitioning floors, but rather stay on the same floor, the tool creates details and units on the level above, which leads to wrong floor plans (adding stairs where there aren't). These details and units have then to be removed manually.
Can someone confirm this behaviour?
Thanks,
