Room within a Room

[Yellowpeterpan]

I have on my DXF model a large room (LIbrary) which has a lift and a couple of room in the middle.

When a run Contruct DXF it does not recongnise the lift shaft and the other room and draws a line down the middle of them.

My question is how do i get round this?
