    You are correct, it's supposed to be 10'. Looks like you've figured it out. Mine looks just like yours but when I tried to extend the right side down to 10' it gave me errors. I must have an offset screwed up over there somewhere.
    I told you that roof was not possible. So what you really wanted was this....

    Oh by the way... multi plate heights, suck in Revit. Try mixing in using pick walls with just sketching lines for your foot print.... Add in a few different pitches in the same sketch... you'll soon see why many break up these roofs into pieces.

    Yep, that's pretty much it. I tried to break it up into 3 roofs, but I couldn't get them to line up correctly. Either the ridge or one of the roof edges was always off.

    So are they supposed to be in the same plane? The gables on the main roof? I think it can be done....but the ridge line won't be horizontal....

    Well, sort of.

    The eaves are on 2 planes, but they should rake up to the same plane. If that makes sense.
    The top eave is 12'. the bottom is 10' but it's a 6' run at a 4:12 pitch so it gets to 12' at the same place as the 12' plate.

    Not sure if this was recommended yet, and I skimmed most of this thread and didn't see it mentioned:

    While in sketch mode, select a sketch line that represents the edge that is supposed to have an eave with a different elevation, and then in properties, set the "plate offset from base" parameter, and then finish your sketch. I find that most people don't realzie the sketch lines have properties that will control the outcome of the roof.

    As usual Dan has done the proverbial mole hill mountain thingy.
    I an ideal world to solve complicated roofs in one roof would be great but that takes a lot of understanding of pitch lines, pitching heights and understanding roof planes before they are solved.
    Personally I use a multi roof system when things get complicated to resolve pitching height, pitching line issues and have found Revit to brilliant at how it can handle (almost) anything you can throw at it.
    I swear by using "pick wall / extend to core" to lock pitching lines, then just extend overhangs.
    I did the attached project for Dan (have been helping him by PM) but thought I will post it as it may help others here get over their fear of roofs.
    Be warned working with separate roofs that if you move a wall that defines the pitching line the roof intersections will not change but the edit is very simple..
    Personally I really enjoy solving roofs with Revit it is actually very good at what it can do and as I come from a background of many years designing and engineering prefabricated timber truss roof systems I have seen a lot of software that cant.
    Hope it helps.

    Scott, I know about that property. I still couldn't get it to work, but after looking at some of the posts I suspect that I have an error in one of the eave heights. Unfortunately, it's a side project I work on at night, so I won't be able to check it out for a little while as I'm still at work.

    Mark, what are you trying to say?? Apparantly my mind doesn't work too well with Revit. I'll have to talk to the factory about that. Maybe they can fix it in SP2.

    I'm still on 2011 at work (don't ask). I'll check it out along with your emails when I get home. It's really not that complicated of a roof which leads me to assume user error is a big part of my problem.

    On the bright side, I got 4 pages in this post out of you guys!

    What I am trying to say is, it is amazing how sometimes a simple question can create so much input and so much valuable information is extracted.
    Thats why I would encourage all "noobs" out there to ask away, no problem to small, and in the end we all might learn somthing new.
