It's quite easy. You make the sector that you want 3d and assign it a tag to a linedef with the "sector set 3d floor" or 160 action inside of a sector outside the playable map that's a triangle. Texture it how you want your 3d sector to look and match the floor and ceiling heights to fill out the 3d sectors you made for it. Make sure it's pointing to the right sector and that type is 1 (solid). Pic related shows a sector with two basic 3d floors. In the top pic I have the cursor pointed at the floor so you can see the sector tag. In that pic I used two triangles with the same tag to make the floor that the shotgun guys are standing on and the roof above it. There is only one linedef to make special and the sector floor and ceiling height make the bottom and top of the 3d floor defining thickness.
