How do I create a single roof with different base heights?

[Steven_Cunningham]

I have this roof issue where the front of the roof is a hip that is about 8" higher than the main part. would be easy if I could join the two roofs, but because of the overall width of the house, this part of the roof peaks higher than the main part of the roof, so I cannot simply join them. I've had to create two separate roofs overlayed on top of each other, but this is going to affect the demolition and renovation of the house. My question is: is it possible to create this roof as a single entity? I attached the .rvt

Take a look here and here.

That almost worked! I tried it once, but obviously didn't have the base heights just right all the way around and the whole roof went kerfloopy (technical term). Put it to rest and just came back to it and while the roof seemed to work with about an inch gap in that little jog, I never could get the lower portion of the roof to join with the wall below the higher portion.

Are you meaning that you want to make all the hips roof into one monolithic roof, but that it's problematic because of the eaves? I looked at your file and I see all the roofs are the same plate height. Because of that, I can see that this can be done as monolithic -- without the eaves. So, what about a different approach? What about doing all the hips as a mono roof with no overhang, and doing the the eaves as a separate roof, and join them to the mono instead?

Am I crazy off base with this one? Well, It happens sometimes. Good luck to you.

If you attach the wing walls to the roof, join/unjoin roof tool works fine. You can detach afterwords.

Check the other solution as well - see attached file.

Oops, I guess I was “off-base”; hadn’t noticed the sketch boundary’s “Plate Offset from Base”.

But, still, I don’t think I would have thought of your solution immediately, Pij.

“Offset from Roof Base”. Good thinking. Nice job. Thanks for posting it.

Well I'll be darned! Thanks!
