Cannot draw rafters for stickframed overframe

I can generate valley set trusses in a roof over roof situation, with a truss base plane drawn.

 

But I want to stick frame the set and the rafters are not generating true in 3D.  Drawn in plan view they look OK and I thought they were going in pitched, but they are level with no pitch and in the lower plane on which this over-roof sits.

 

What's the trick?

Sorry for the bandwidth.  Figured it out after searching for and finding a Chief how-to video.

 

Overframing with rafters is sort of like the inside-out version of overframing with trusses.  Trusses, you need to build the truss base "roof" right atop the lower roof.

 

To stickframe an over-roof valley set, the over-roof has to be set as frame-over in the structure dialog, so you are specifying it has framing, and I guess the Chief coders used this setting to determine which roof governs in autoframing.

 

And yeah, autoframing.  The only way you get overframing is to autoframe it.  Drawing manually to attempt to generate rafters does not work.

 

In my current project with this situation, I have a two-pitch situation happening on one side of the roof, and for some reason Chief does NOT generate the 2x10 shoe plate for the center plane of the three-plane over-roof.  This, on both sides of my center bay.  All settings same for overframing in these six over-roof planes.

 

In this plan view, I highlighted the overframe planes that did not get shoe blocks.

I don't need to show it in 3D and so have just used CAD to depict the missing shoeplates.  This pic has them highlighted.

And in 3D, you see them missing, and the bearing ends of the rafters not cut to seat on a shoe.
