Warning: "Cannot Produce a Roof Plane"

[HumbleChief]

I was changing some walls around on a very simple plan and I got this warning. Chief cannot build a roof plane over the back wall

 

Stumped. Thanks

 

Looks like it has something to do with an invisible wall/gate creating the situation. Hmmm... It's invisible, no locate and no room def but Chief wants to build a roof with it. If I delete it the roof builds OK - but I kinda like it.

 

Weird. If I unselect 'no room def' the roof builds over that now defined room. If I re-check no room def then the rear wall roof rebuilds OK. Never seen this before...

To correct I:

1. Made sure all the property walls were "no locate" (yard walls).

2. Turned off "full gable wall" from the wall with the fireplace.

Worked. Here is a vid.

Thanks for taking the time Johnny but in this case I want a full gable wall on that chimney wall. It seems to have something to do with that little invisible/gate wall but I'm not sure I'll ever know what the cause is/was.

Larry,

 

What I found odd was that even your roof for the section that did draw where invisible wall juts out is in two pieces. Anyways, invisible wall is off by a fraction from main walls. Snap them together and it draws fine.

Found the same thing.  In fact, after invisible wall is aligned, you can then unalign it again and it will still build fine.  Or just delete that invisible wall...don't see that it is doing anything for you.
