Another newbie roof

[Chordmeister]

Having spent a lot of time searching through threads and just as long experimenting, I'm flummoxed....

I'm trying to create a simple duo-pitched roof with an apex at the centre of the house, BUT one side of the apex the roof will pitch to the ground level of the attic, the other side will be a much shallower pitch to a full width dormer across the house.

I attach a picture to illustrate - what you see is the side of the house (the gable wall) with the standard pitch one side, and the shallow pitch to the dormer wall the other.

I'm using v7 suite (not pro) - surely this is possible?

Thanks in advance.

Hi chordmeister,
Welcome to the forum...
I think you are trying to create a Saltbox Roof.

See this thread: http://hometalk.homedesignersoftware...=salt+box+roof

Thanks, I think I've got as far as creating a saltbox, but the crucial thing is, I always end up with the apex shifted from the centre. I need the apex to stay in the middle while the pitches are different each side of it...

When I say 'apex' I think I mean what that thread refers to as a 'ridge'.

You need to adjust the ridge center using the pitch.
In my pictures the 2nd floor front wall has a pitch set to 4/12.
The first floor rear wall is set to 12/12.
I added a wall on the 2nd floor. Make it a "knee" wall.
I set it's pitch to 10/12.
Create a Full Render then click on Window and select Tile Vertically. In the Layout, move the "knee wall" on the 2nd floor until the roof plane lines up.

Just for my own clarification and perhaps CM's...

So the trick is to make a second floor over half of the house?
What is the purpose of the knee wall?

If a shed dormer was created on a single story, would small end ledges have to exist beside the dormer. IOWs can a shed dormer take up the whole roof side space?

Thanx roofmeister.

If you don't have the 4 walls, you don't have a 2nd floor. Calling the wall a "knee wall" in the program makes it get cut off where the roof plane crosses it.

Brilliant. I was very nearly there myself but lacked the lateral thinking required! (was in the mindset of trying to set the ridge position by the position of the left wall on the 2nd floor rather than by adjusting the pitches).

Thank you very much. Roofmeister you are.
