Flat Roof Design

[wesdutka]

I know this has been discussed but can't seem to find a satisfactory way to do it.  Everything I've read and tried are partial solutions...I usually just end up using 3d solids for both the parapet and shadow boards.

 

First I'll describe what I'm wanting to do.

 

1. Create a 1/4" / 12" roof slope 24" depth trussed roof with a 24" overhang.  The overhang structure would basically be the roof trusses cantileved over the exterior wall the 24".  Shed roof.

2. With this I would like a 3" parapet and a 8"x3/4" shadow board.  Truss fascia to be 7/16" osb and stucco finish (maybe not achievable from what I can tell).

 

Is there a satisfactory way to do this without doing a lot of "fudging" using 3d solids?

 

If anyone can do this in a rectangular boxed room I can take it from there from their specs.  Am I expecting too much from this program to achieve at least most of this?

 

Thanks in advance.

Do you have a rough sketch what you're looking for?

This is essentially what I'm wanting to do...the parapet and shadow board on this one was done with 3d solids.  Is there a way to create this without the additional steps?

You need to add a floor. 
 

Your exterior walls are your parapet walls. Add a wall cap. 
 

Control the height of those walls with the rooms ceiling height. 
 

Draw your roof plan within those walls. 
 

A single sloped roof to one side that sheds the water off that side. Or a four sided roof that converges to a drain in the centre. 
 

for the shadow board just add a moulding polyline
