Assuming you already know how to model a box without a sloped roof, and assuming you are trying to model this in the IDF editor specifically, and assuming you want a simple slope; here is one approach.

  1. Find the roof surface, and increase (or decrease) the z value on the edge or the roof you want to change
  2. Find the wall surface that sits under the roof edge you chanced and adjust the z value of the upper two points on that wall
  3. On the two side walls that have an edge both on the low and high side of the roof, change the z value of the upper point on one side to match the wall and roof you just changed.
  4. The last wall should not need any changes,

Hi! Thanks for the hint. This actually worked, and I was also able to model it in two parts at an angle from center (like roofs in traditional buildings).
