Slab with multiple openings

[AGFreeman]

Hi Guys!

After assigning thicknesses to slabs openings in them disappeared. Previously I created all openings in these slabs for column caps and everything worked perfectly (mesh was OK), but when I started to assign thicknesses openings just filled up. Now I cannot create them by any measures.

Thanks in advance!

Unfortunatelly you have made ACIS objects...in such case you have to cut hole in one object by another (I think this "another" must be 3D object = solid)

I recommend to make model again without ACIS

You made me sad =( because this is only 1/5 of the entire slab.

But anyway thanks for your quick reply.
