Can't make footprint roof

I have a building with four basic Generic Walls. It has a simple footprint
roof. I selected all of the exterior Walls, did Edit/New > Duplicate. I
edited the structure of the new Wall Type. I changed it from the generic
material to a CMU + Air + Brick configuration. When I try to OK this, I get
the dreaded "No can do" dialog. the exact message is "Can't make footprint
roof" and the only option is "Cancel."

OK, so I cancel and I loose all the edits i made to my custom Wall Type.
Now, I assume that the Roof is attached to the Walls (or vice/versa), but
this is particularly frustrating since I end up loosing all of the work I
did on the Wall type. So, the question is, how do I find out what I need to
do to overcome this? The error gives no details and just says basically
"sorry pal, out of luck." Do I need to detach the roof? Something else? Any
help appreciated.

Thanks.

Change the Eave type of the roof to Plumb Cut from two-cut plumb/square (in
Roof Properties), and then try changing your wall type. See if that
eliminates the "Can't make Roof" error.

90% percent of the time that error has to do having adjacent slope
defining lines with different eve heights that would produce a roof
Revit can't create. hit the "align eves" button and check the eve
heights, align them and the roof will work.

You used to get a warning about this but, now that Revit can do some
roofs with misaligned adjacent slope defining lines, so the error no
longer appears.

Not sure if this will help in your particular case.

It already was plumb cut sorry. It is basically a flat roof. I used slope
arrows to give it a 1/4" in 12 slope. There are actually two roofs side by
side. (not that that should matter).

Thanks.

You may also want to separate creation of a new wall type and changing
existing walls to use this type into two separate transactions. Then failure
to make a roof would not force you to loose wall type edits.

OK, so I selected the Roof, clicked Edit, then Align Eaves. I got this
warning:

At least two Slope Defining Lines are needed to perform Align Eaves.

None of my edges are slope defining. I used slope arrows to make the roof.
Any other ideas?

Yeah good idea. I learned that the hard way didn't I... 🙂

Hmmm...did you tell Revit to "Extend the Roof to the Wall Core" when you
first made it? Trying to figure out why it doesn't like your new wall
style.

The dreaded Revit Monologue box....

I don't understand why it can't be a bit more informative.

I was able to fuss around with the Roof sketch and get it to finally stop
complaining. I think it had to do with the location of some of the sketch
lines. I moved a few to the opposite side of the Wall and got it to work.

Thanks for the help.

Did you have some sketch lines on the outside of the core and some on the
inside? I've had that cause problems before...

I believe so. When I got them all to the same side, it seemed to be OK.

Interesting. I had the same thing happen to me - however I've also noticed
that if the sketch line is to the inside of one wall type, consistently, and
to the outside of another wall type, consistently, on the same sketch, it
works. But if you alternate sides on the same wall type it gives you the
monologue and doesn't wanna do it.
