Creating a Dutch gable shifts the pitching point

bainoParticipantWhat is the secret to maintaining the hip position when creating a Dutch Gable? Whenever I do it, the hip moves away from the intersection of wall frames. None of the properties of the roof appear to change.
Also, has anyone used Envisioneer for 3D shop drawings of a steel portal and hips with connections for welding fab? Or would you use Sketchup?

FynrDzynrParticipantEnvisioneer has done this as long as I can remember . . . and that’s since v2.5
Change a Hip to a Dutch & for some unknown reason it defaults to a thickness (b) of 6″ or 152mm instead of retaining the same thickness as the rest of the roof.
Easily fixed by correcting as soon as you do the conversion but still very frustrating.hth

Staying on topic, for measurement (b), do you include the thickness of the rafter, purlins and roof cladding?

I always include everything, just in case the roof butts against an upper wall with windows. I want to be certain there’s sufficient clearance for flashing. Tile roofs are measured to the top of the overlap.

Ed StaelensParticipantHi Chris,
I have found for the kind of shop drawings you are referring to that it’s easier to create the basic structure as far as I can go in Envisioneer, then export to Sketchup for the other details. It’s easier to make those things and extrude them there.2016-11-30 at 19:19 #10129bainoParticipantThanks Merv. Correct solution, duly noted
And thanks Virtual (misplaced your name as there are no names anymore on forum). I take your point.2016-12-02 at 18:31 #10127
Flowers323ParticipantHi Baino and Merv, as a long time user, I offer my opinion that it is user error that makes the hips move.
To make a dutch hip you are changing the roof, why would you not check the gable settings before you insert the gable?
2016-12-03 at 18:50 #10126bainoParticipantThanks for your comment Flowers.
I don’t think that the gable should have any bearing on the position of the hip, or the thickness of the roof.
As a gable get bigger in size, it is really just creeping along the existing hip rafter.
I am unsure if the roof thickness change back to the default is intentional or not. IF you change the seat cut for a rafter in the ‘support and details’ settings, the fascia returns to the default as well. Is this intentional?
Cadsoft input would be good.
