That's not the most memory efficient as it creates in-place families.
I've used the floor slab edge tool and fascia for trim. It works pretty
well.
A little known fact is that both the fascia and floor slab edge don't need a
floor or roof to attach to. You can simply draw lines and have the hosted
sweep attach to them. Select a drawing plane (surface or named ref.. plane.)
Sketch your lines. Then use either the Host Sweep > Fascia or Floor Slab
Edge. Pick the lines and you have your trim. If you sketch the lines by
picking and locking them to the edge of the ceiling - they will remain
parametric.
All that said, Revit really does need to add a few new sweep tools (really
the same tools which just make new sub-categories.) The should have a
ceiling sweep that attaches to edges of ceilings and hatch lines on ceilings
for cornice trim. They should add a base trim tool which attaches to a floor
line a slab edge sweep, but has a subcategory of base trim. The base trim
should recognize openings in adjacent walls and automatically trim.
They have all the technology - they just need a few tweaks.
You might also consider some generic models if most of your areas are
rectangular. Placing a generic model is faster than trying to create a
sketch to sweep. There is quite a bit of flexibility here as you can chose
hosted, non-hosted, two pick, etc. for the family type.
