best way to do this gable plus extension?

[SHCanada2]

I'm trying to recreate this 14:12 roof. I have the floor plans but not the elevations. Can it be done auto some how?

 

In this case I broke the upper floor wall at points where I guessed it might instersect the top of the second storey wall, then edited (including the pitch) and extended the 2 gable roof planes down past the second storey walls to the main storey.

 

But it was a bunch of trial and error rebuilding the roof planes( so I did not have to manually edit the roof planes)  and there is no place to actually put the 14:12 pitch, so  I had to edit the two gable roof planes after each rebuild anyway.

 

Anyway, is there a suggestion on how to do this better. The only thing I thought is to draw 14:12 cad lines on the elevation (as the porch roof and upper roof are already built), then measure from the outside wall to where it intersect with the top of the second storey wall.

 

The pother thing I thought to do because there was no where to specify the 14:12 pitch, was to change the default roof build to 14:12, and go set all the walls to the other pitch (7:12) except porch (~4:12)

 

any better ideas?

AFAIK, auto-gen roofs spring from roofs and the roof directives in the wall spec are what make the roof planes.  I don't see walls that can used.

 

The upper part of your feature is a dormer, and you can use dormer tools to generate something there to get you started, but I think you'll need to do editing to bring the roof gable overhang down to the lower porch roof.

hmm, not a bad idea as i can move it around and leave the autobuild on. I'll give it a whirl

welll, it certainly is interesting. I can set the eave to like 80" to get it to go down past the 2nd story top plate but that cuts into the room

 

looks like the best i can get is:

Did you explode the dormer?  Explode it and turn off autobuild, and get busy editing the top main roof to chop out where the dormer lies, and the dormer roof plane overhangs to extend to the porch roof below.

Learn to manually build roofs.  I only use  the auto roof to get me about 80 percent of the way on the simpler roof systems.  I have been using chief for a while and always built manually because I understood it better.  Be surprised how complex one can get doing it manually

I did not try that, I thought about it, but thought that was similar to how I first did it (broke the wall and set it to a gable, then adjusted the roof planes pitch and eave down). But in thinking about it some more, the dormer does have an advantage in this regard, in that I could just type the values (width, pitch, eave length) into the DBX, and see where it got me where the breaking of the wall, I only got to set it to the gable). 

 

There is something a little funny. if the dormer wall height is 10" it looks like:

 

if I put it to 6" (lowest allowable) to tray and get it to the end of the top plate it looks like:

I then alter the planes to get:

 

but when I alter the roof plains manually to get rid of the eave across the bottom  the wall is missing:

 

then I bring the wall down to cover and the open space, and then try and get rid of those two little ends and then it all goes to He double hockey sticks. ...maybe the first way was quicker...or use the dormer to find the distances, then go back to breaking the wall and setting it to a gable
