Found it nevermind .

Hi,

Just starting to use SH3D.
I started the turorial: for sloping roofs and ceilings.

All is good explained, but now I'm stuck at step 3 (3 - Sloping ceiling with room-high dormer)

Can't find out how to draw the roof as explaind.
They ask to open a new document in SH3D and it's from that point ...
