Automatic Hip roof wont work.....

Each time I try to "auto-roof" this shape, it tells me it is invalid/intersecting... but its not...

It is a bit weird...

I can make the roof manually, but I am keen to know why this particular shape wont work..

I have made hundreds of other shapes, some very weird and have never ever had a problem (unless it was justified) so I am mystified as to why this particular shape wont work...

Version 9 (latest build)
Winxp, 1Gb RAM, P4-3.0

(I have tried to attach to post but it didnt work, so I have put it here...

Can you post a picture of the shape?

Nefarious:

I was able to get this to work when the the roof slope is set to 45 degrees during the roof generation process. When I used 25 degrees and 35 degrees, I got an error message and the image on the right. I was able to change the slope to 25 degrees after generating the roofs with a 45 degree slope (image on left). I don't know why the lower slope setting creates the problem. Hope this helps.

See below...


Weird thing is, I did this on another computer and it worked the first time, then I did it again at 25 degrees..... tried and sure enough the message came up...

I changed it back to 45 degrees.... guess what.... message came up...

I reproduced it. This is a bug. I report it to GS.
