When I use the join roof tool one would assume it cuts the roof where joined right? Well it doesn't. I'm curious to know if there is someway to set the Join roofs tool to automatically cut the roof. What I mean is I created a gable porch that is joined with my main roof. But the main roof is not cut underneath and therefore has an over hang under another roof. That just makes no sense in the world of Architecture. So does anyone know how to do this? Picture of issue is attached. Thanks, Lorne

Lorne, you need to use the dormer opening command. I would disagree and say that there are circumstances in which you do not want one roof to cut another roof (crickets, areas where you might have a flat ceiling and don't need to cut the roof, etc). Anyway in your case you want to do it, so use the OPENING, DORMER OPENING command under the MODELLING menu. Good Luck.

This is very easy to achieve in one single sketch for the roof rather than trying to split it up... From your pic it looks like the eaves height is consistent so there is no need to split them is there?

Yea it actually is one eave height so I guess I could do those two as one roof. I didn't even think of that. We have a pretty simple roof system but Revit thinks it is complicated and originally we tried to make it one roof. But Revit didn't make it correctly. Is there a way to fix this? The first image is what Revit did when we made it one roof. Then the second is what we did in order to make it work. We split it up into 7 roofs.

Ok now look what it's doing. When I create just this wing of my house with one roof. Then I get a line across the top of the roof when they are one object. Why is this?

hi it is possible to get revit to make one roof like that one above, but it takes too long. i would of done that roof as seperat roof just like you did. also this bit of advice i always give my clients, if it seems like it is taking ages to make a roof and revit isn't not doing it right, delete it. then use modeling-create-roof. you can make any roof with this tool and it doesn't take too long.

Just deselect the aligned roof edge as slope defining. Its getting confused because there are two aligned edges defining the same slope... Looking at that roof myself i got it to work using the standard roof tool, but did have to break it into 3 pieces. It was fairly simply once i did that though...

I know this is a late reply to this but ran into this problem myself yesterday, read the thread and it did not help. In case anyone esle runs into this the simple soultion I found is to draw your roofs (you can do it in one piece) go to a plan view select Vertical from home tab, select the roof you want to cut from, sketch lines where you want to remove the overhang and click finish. Pretty simple. Again this is answering a question from 4 years ago but just in case anyone else runs into this there is an easier solution. Not sure if it matters but I am using Revit2011.

Hi there, just to add to the confusion - we have two roofs, one is a simple gable and the second will be a hip roof, all at 3:12. We're trying to connect the ridge line, and the new roof will be taller than the old roof, but we can't get the correct construction this way. Any clues? I.e. rather than the flat plane being cut off there would be a triangle that continues at the untouched gabled slope. I'll try to clarify more if necessary :/
