HOW DO I CREATE ARCHITECTURAL FLOOR FOR AN IRREGULAR SPACE ?
Change Place By: method to flood? Is the curved line a slab boundary or just a finish? If the slab boundaries are all straight you should be able to snap the boundary vertices to ends/junctions of walls. Work in Top view having set the correct floor active in Floor Manager and ensure ACS Plane and ACS Plane Snap locks are on (use the Icon Locks toolbox to do this).
Also note: for slab penetrations use the Place Wall or Slab Penetrations tool to create penetrations/opening that can be scheduled.

It's hard to tell without more detail, but you should be able to place both a Slab and a Space using an existing shape. The yellow outline is the original shape which I first used to place the Slab and then the Space.
If I wanted to modify either one I can just grab an edit handle and adjust.
Is this what you need to do?
