Hi All.
So question or issue I am having on a portion of my complex roof I cannot figure out. I put a basic gable roof that has a 7/12 pitch and the gable looking at east elev. ridge line is supposed to be inline with west elev. gable ridge line (see screenshots). The roof line was correct east and west 1 ridge; however I had to join perpendicular gables (2 10/12 slope; 1 7/12 slope) into the main roof. All elevations and roof lines are correct; however the east portion of the main roof front slope disconnects and the ridge line moves upward like it is 2 separate roof lines? The vertical line in both screenshots is and was the correct ridge line and thus you can see how the roof disconnected the front portion of the main roof. You can also see the east elev. front slope is also down from the back slope by about 2' which enabled the main roof to have both 7/12 slopes.
How can I correct this? I tried also to create main roof w/o the front slope then create another roof that was just the front slope but then that created more issue with the gable that joins into the front slope of the roof.
TIA!
Cheers!

Thanks. So I guess I need to split the roof into 2 sections but when I tried that I had other issues when joining the perpendicular gables. Anyway I'll give that another try and report back.
Cheers!

Oh, it's one roof doing this? Simple fix. Remove Define Slope from the eave that is inset.
Thanks for the tip but as I said I had done the offset but then separated the roof into 2 "main" pieces. The piece I separated was just the piece over that 1 area with raised ridge line. I simply made a lean-to and simply tweaked that portion down slightly to match other roof piece ridge line. Tried to join the 2 pieces but it tells me 'roofs cannot be joined.' Not sure I really need to join the roofs because it looks complete but I'm sure it is recommended to join roofs that are in pieces.
Another issue I have now if the perpendicular gables being joined to main roof sections however the portion shown in the screenshots below of deleting a portion I do not want to be removed.

As you can see after join the gable gets removed leave a void between the wall and the facia. What I would expect is that with 3D modeling faces are joined in all directions so as the one on the far right in image #1 the main roof would extend the main roof to "deadend" into the gable roof face? Also on the ones on the left the main roof is through the gable roof face and not trimmed away that would again create a "deadending" of the main roof into the gable roof face?
Is there a way to accomplish this even if I need to manually select each facia face and join to roof face...
Cheers!

Yes exactly. However I assume you extended the front main roof line and that is not correct on how house is actually built because the roof line overhang is in line with middle of the house roof overhang.
I lost internet so keeping this brief from my mobile phone.

One additional thing to note is the area that appears to be correct is actually not because main roof is extended through the gable roof if you spin and look up from under roof line. I know a soffit might hide it but still should be trimmed back to face of the gable roof face...or that's what I thought would happen.

No, I didn't change any overhang. It's exactly the same dimensions received in your file. I just made the gable eave a Roof by Profile so I could extend and clean-up the conditions at "B". In the field, the rough framing it will probably look closer to your original. The roofers will likely have to clean up that intersection with blocking.
Regarding your follow-up post, you can clean-up that condition where the roof protrudes through another by using a in-place void to cut it away.
Thanks again I really appreciate the guidance here! I am new to roofs in Revit so-to-speak and never really did one the complex and just really learning when to use the different options...Never used roof by profile nor the cut void you mentioned. I look into the new file and hopefully see what you did. I am assuming my existing plans with a 7/12 slope for the "main" roof are not correct because I couldn't get anything close until I changed main to roof sections to 6/12 slopes and the gables are basically 9ish/12 rather than 10/12.
Here is actual picture of roof plan and elevations and my roof only looks close and I can tell not exact at all so I really need to try other roof functions to handle offset ridge line on 1 side of house...I have looked the internet over and nothing comes close to this complexity! Maybe if I can ever figure this roof out I will create a tutorial video to post...ha, ha!
