Can anyone direct me how to (if possible) place a roof onto a sloping building.
I am drawing a large shed (over 100m long and 17m wide) which is being constructed on a 0.39° sloping site, the walls and roof is to follow the slope of the site, the roof is sloping 19° to the ridge which i can do but i can't place it on the slope of the site as each end 'needs' to be at the same level.
Essentially i need a roof sloping 750mm from one end to the other with a 19° slope to the ridge width ways.
Any help will be appreciated.
You can create a reference plane perpendicular to the slope of your site and the create a roof by extrusion based on the reference plane you created.
You can create a mass with the precise bottom point elevations and create a roof by face.
Or cut the roof with a sloped void at the bottom.
But 0.39 degree is considered level in normal construction. I would build the roof flat.
Do the math for your actual slope. Either add the two perpendicular vectors, or use trig, or whatever. Then just make a regular roof by footprint, and instead of assigning any edges to define the slope, use a slope arrow on a diagonal.

Attached is the roof using Roof by Footprint and slope arrows.
I normally would consider this flat but i am drawing it around a structural IFC model so the flat roof ends up sitting 750mm higher than the rafters at the lower end of such a large building.
Thanks for all the input, i will try the above suggestions now and update as required.
