Create Roof Command Failure

Recommended Posts

Aloha,

Each time when I run the AEC>Create Roof... command I am getting the following error from VW:

"Could not create roof, house drawing is too complex to compute roof."

See the attached file. Is this polygon "too complex" to create roof?

When I tried the command on a simple rectangular polygon it works fine.

Thank you!

Yoginathaswami I tried and was also unable to get it to work. That surprised me because it is not a particularly complex roof. The odd thing was though that if you turn the short edge on the LHS into a gable the roof will form. You should bug submit it.

In the mean time fortunately it is a roof you can easily model manually using individual roof faces.

Maybe it fails because the left hand part is a hip roof projecting out of a hip roof - it's easy for us to see how it should be done, but the program struggles.

You could also build it in stages, first as 2 separate roofs, then ungroup the small roof (or both of them) and join up the roof faces.

Thank you, Mike and David:

I ended up doing as two separate roofs and combined them manually. As Mike said, it really surprised me when the command failed. I'll submit bug.

Thanks again for both of your help. Aloha!

When I have a roof fail, I find that if I draw out a series of polygons individually (typically squares and rectangles, being sure that each contacts the edge of the other), then Modify>Add Surface, that the resulting polygon generates a roof which does not fail.
