Hi.
I want to get a solid of the interior the building. If I go through the rooms, there are gaps in between. How can I fill them? I came up with a method like this:
In Python, temporarily delete the interior walls and replace the location with a room separator. But I can’t find how to write this.
you could try grap all your interior walls solid, probably with geometry + from clockwork so you can get without insert etc…and then your rooms, and solid union…or get center boundery from rooms and union maybe 
If you use the centerline of the rooms when pulling the geometry to remove the ‘wall’ gaps, however I am not sure how well that will work for roofs and floors though - what’s the end use? There may be a better process to get what you’re after.

yeah guess for floors and roof, it will depends on the rooms height, in that example here, so indeed there could be a better way…depends
Hi! Arhilab’s RoomBoundaries works here:
It takes Core boundaries by default. You can extrude them after with extra values to eliminate horizontal gaps.

It would be better for my scenario to get the rooms separately. I tried the first method I thought of for this and I succeeded! I can’t wait to share it with you.
