Hey Folks, thanks for your time. I've attached two screenshots of a half finished house file (.rvt file is too large), in which I am having difficulty figuring out how to properly form one of the roofs. That jog on the southern side of the roof is not supposed to define slope, that box is not checked, and the "offset from roof" parameter seems not to have any effect (see Wrong1.jpg). However, when I change the offset of the eave directly to the east, the roof arranges itself into the gable-within-a-gable thing that I'm looking for, but the ridge is off center, and the eave is too high(see Wrong2.jpg). I basically just want the roof to follow the framing that I've put in. I'm a new user, can anyone help?
Thanks a lot,
Noah

You need to label the roof edges 'A' 'B' 'C' etc and define the problem better. What you want is most likely do-able.
'Offset from roof' only gets applied if the edge is sloped.
Whether you used the 'pick walls' method of generating the roof edges vs just sketching (including the pick option) will impact the outcome of the roof and the relationship with the 'eaves'.
The roof ridges will only line up in plan if the roofs are at the same slope and the same span.
The roof surfaces will be co-planar if the coorisponding roof edges are at the same height and same slope.

Take a screen shot of your roof plan in sketch mode so we can see how you have it set up. It's a little confusing as to what you are looking for, your second picture looks correct, other than the weird saddle between the roofs perpendicular to eachother.

Thanks for your speedy responses. I have actually just remade the roof in question in 3 pieces. Next time I post I will be more clear and include labelled diagrams, but in this case, I'll just say that it wasn't my intent to align the ridges. It was rather to align the eaves in elevation. I realized that in this case, and pardon me if this is vague, that two parallel, slope defining lines that were supposed to define the smaller gable nearest to the viewer were misaligned because of the dormer. I believe this means that the roof could not have been made in one piece anyways.
Either way, problem solved, thanks for your help.

Absolutely. Break the roof up into peices. One of the first things I tell people. Even though we picture it as '1' roof it's far easier to model it in sections.
Then you can move and manipulate each section imdependantly.
Finish up with the 'Join Roof' and the 'Join Geometry' tools. Note that 'Join Roof' can extend a roof edge to another roof, a wall or a floor. 'Join Geometry' doesn't alter the physical shape of anything but just cleans up intersecting geometry of almost any element type regardless of category.
