Hi,
- Ceilings appear over rooms (if ceiling check-box in room properties is checked). However, if you have roofs that do not reach the ceiling (or lots of strange angles), this does not always produce the desired effect. BUT, drawing a roof will solve that as the underside also will be the ceiling.
- 'Saddle roof' is ambiguous, but for a roof with normal surfaces and angles, you could either combine and scale the roof models available on the models page, or
- You could make your own, for instance like this.
- Draw a wall the shape and size of your roof - but as if it stands on one side.
- The height of the wall equal to the length of the roof, the corner should be the same as the angle of the roof. Add colours etc.
- Select the walls and export selection to .obj format.
- Import the .obj file and rotate it with the green arrows in the import menu.
- (If you need skylights, you should add the windows under step b)
- Draw a wall the shape and size of your roof - but as if it stands on one side.
ok
PS - For a saddle roof with convex curves, i.e. a hyperbolic paraboloid, it would be more complicated...
For other challenges, Hansmex' roof guide will steer you in the right direction.
