Columns, Beams, and Roofs
I am trying to create a basic barn skeleton. Think carport that is a cube. No walls, just beams and pillars. I found the beam and the column, and they are good starts. The two items that give me trouble are:

[1] the columns need to go three feet into the ground. Alas, negative elevations are not allowed. (Maybe one can draw a floor level that is 3’ higher?)

[2] I want a roof on top. worse, I want it to be angled, so on one side of the roof, it is higher by 2 feet than it is on the other side. It’s really just a slab of steel, sitting on rear pillars that are 14’ high and front pillars that are 16’ high.

Has anyone solved a similar design problem? If so, could you please share a sample or advice?
