Combine surface to one Surface

Hi!

I have multiple surfaces that are somewhat apart from each other. I would like to make one surface from these different surfaces. (like I have one surface for one floor) The pieces between the surfaces then need to be filled in. How do I create this in Dynamo? My input is a IFC-model. In the Watch I have filtered all de bottom surface. (My Polysurface now ar not filled in).

You’re making the problem more difficult than it needs to be this way.

Intersect the level with the exterior walls instead, or best yet just grab the floor slab.
