Joining Roofs

Trying to join a shed roof to the adjacent roof pitches on three sides... The process worked for two sides, but having trouble with the final join.  I just dont understand what the difference could be.  file attached.  The roof I'm trying to join is at the back of the house, small shed roof between two gables.

The problem is that the shed roof which needs to be joined to the gable sticks out. Here is what I did - I edited the sketch of the shed roof so that it intersects the gable the way that I want it, and then I used voids to cut the extra parts away.

 

To create Voids = Architecture>>Component>>Model In Place>>Void Object

Ok... that works for me. So much to learn. Some day I'll be really good at this.

OK. I'm sitting down with my drawing again.  You said you sketched the shed roof far enough to the left so that t intersects fully with the steeper pitch.  Then you voided out the portion of the shed roof that I didnt need.  Im assuming you voided out only that portion of the shed that is not visible outside the building envelope.---OR---are you able to void out any portion of the shed roof that extends past the valley?  Even what could only be visible from inside the attic?  I will go work with it now, and that may answer my question, but if you have some insight to this that would help me greatly... Thank you..

I dragged the sketch of the shed roof over the gable roof till it looked right in a 3D view. Then I created the void to cut away the extra part of the shed roof OUTSIDE the external wall. Whatever is inside the attic area would only come back to bite you when you cut sections - and in that case you can mask them out with a masking region.

 

Good luck!

For your particular model, it is a tad more than just make one roof larger then cut it in order to make them all joined, see screencast and model.

that's what I would have expected... In this case it's ok, as I'm not going to be doing a section view of that portion, but I do need a good understanding of all the many different methods at my fingertips... Thank you for your thorough replies...  I will play with this tonight.

I noticed that you started your manipulation by stretching the upper roof towards the left most gable.  Just wanted to know if this was a better way to do it than what I had done. (FYI, the other front to back gable is a full vaulted ceiling, so I cannot have any leftover roof pieces hanging out up there) I have struggled a little bit when trying to get those roof planes to join.  Sometimes they go right together... other times, it seams that I must utter the secret password to achieve the results.....and somebody keeps changing the password.

Enlarging the upper roof first is necessary so that it can cover the wider lower sash roof in order for the sash roof to join to it.  The enlarged roof still join cleanly with the other higher roof as before.  That is the beauty of using the Roof Join tool: you don't have to size the roof perfectly, as long the dominant roof surface wider than the secondary roof they will join.

 

Look at the revised model.
