Just had this issue with another user in a training session. In a bump out similar to that attached files, but with equal sides Revit makes life simple in modeling the roof. But with the angled sides become unequal to the outermost side life gets ugly... and users in training get frustrated. The pitch of the two angled areas of roof must be different than the other three sides to get the roof to come to a point. We have other software that we use to design trusses that will calculate those pitches and define the roof planes for you, but this software isn't used in the process till much later and basically it's double effort anyway. My question is what method do others use to get this type of roof to come to a peak point for all roof planes?
1. I thought slope arrows would be the ticket after determining the height differences and defining height at tail/head method. No such luck. I'm sure it can be done this way but with time constraints and persistence not in great supply from typical users, I gave up on it for now. There were lots of measurements taken, sections made, etc. it seemed way more involved than it needed to be.
2. Trial and error. assign a pitch that you think it might be close to test, and adjust, and repeat as many times as neccessary till it's close enough for your requirements, or your addiction to accuracy is satisfied.
3. This was the final attempt which was to contruct with equal pitces all around. Finish the roof, take measurements of length of roof plane and height of roof plane and calculate the pitch to assign to the relevant lines in the sketch mode.
