Error creating roof

[brg]

HI,

I already drawn the model for a domestic building and when i try to create the roof, I get the error 'Space intersects existing space'.

There should be an error in the model but how to find it and change it.

Thanking you for your help

That means you are trying to draw a zone inside another zone - big "no no".

Try drawing the roof 10m above the other zones then move down.
