Roof Slope in TWO Directions

Anonymous — Tue, 23 May 2023 13:09:40 GMT

I have a roof that slopes both from the East to the West and from the North to the South. How do I model this? Thank YOU!

I assume you are talking about a single roof plane for which the 'fall line' is not perpendicular to a drip edge? Use the polygonal geometry of the roof tool. The first edge you draw is the perpendicular to the slope of the roof - 'fall line' in ski terms ;-) Then you draw the roof edges however you choose. (You can also draw a rectangular roof and then just reshape it with the pet palette.)

If this doesn't answer your question, perhaps post an image?

Odd roofs can also be modeled in 3D with great satisfaction.

Be sure to turn on the status bar for instructions.

You establish the roof slope by clicking three elevation points, then you determine roof extent.

Thanks, Dwight - yup, the more realistic solution (doing it in plan may require math)!

Please see this thread for constructing off angle roofs.
