Top cord bearing roof truss

[MN_JohnH]

I am wondering how to build a roof truss that bears on the top cord like this picture and then I would need to get the wall to frame up to that bearing point.
I have a plan here where I was able to change the shape of the truss and I made the walls to balloon through ceiling and now they go all the way to the upper truss cord and don't stop at the bearing point I created in the trusses with the truss envelope. Also, how can I get the framing  to use my trusses instead of making it's own trusses in addition to mine?

You can get the truss to generate by manually placing the roof and ceiling planes, then draw one truss, edit it to get what you want, then lock it.  Frame the bearing walls and edit their heights.

 

I'd tell you how to it all with settings and clicks and drags, but I don't know how.

This is done by building ceiling planes that are parallel to the roof surface and then generating roof trusses.

Thanks for the responses. I guess I didn’t make it clear that I know how to draw the trusses. The problem I’m having is controlling where the walls frame to the truss.

Basically, I can’t find any setting that lets me define the top of wall framing at a specific point on the truss.

Yes, I can raise the roof and get the look I want, but when I reframe the walls I still end up with the same problem.

For example, what if I want the wall to frame to the bottom chord of the truss? On the lower side I can accomplish that by setting the room ceiling height and not balloon framing through. But then the higher side frames to that same level. If I set the walls to balloon through, then the framing runs all the way to the top chord instead.

What I need is a way to control the top plate height / bearing point of the wall framing relative to the truss.

Right now, when the wall frames all the way to the top cord, the framing gets crazy because it tries to frame around all the truss members.

My second problem is that once I manually draw and place my trusses, then build the roof framing, Chief creates another complete set of trusses automatically. So now I have duplicate trusses plus even more crazy wall framing, and it ignores the bearing points I established in my custom trusses.

So I can build and customize the trusses fine (I think), including locking the envelope with bearing points, but I can’t get the walls to frame to those bearing points correctly.

Again, my sample plan is attached.

Hi John, here's a couple of quick tips.

1. Turn off the framing for the ceiling plane. We'll just use the trusses generated by the roof.
2. For the wall framing, you'll need to manually edit the wall framing. Take note of the elevation of the roof truss bearing and you can use that information to accurately edit the top plate height.  Before editing the wall framing, ,'d suggest resetting the structure to 'Automatic' and rebuilding the wall framing. That will simplify the wall framing so that all you need to do is raise the plates, and stretch the studs.

If I frame the roof and not the ceiling, I still get all the extra trusses. I am not sure what we are trying to accomplish there. Or maybe I am misunderstanding.

All you need to do is  raise the plates, and stretch the studs? That's a lot.
And if I move a window or something and need to re frame the wall I will have to do it all over again?
Also, what if I wanted to have some windows in that upper wall area above the normal ceiling height? I would have to frame that all by piece?

Is there a reason why you want to pocket the wall frame tops up into the truss envelope?  Bring the wall tops up to the bottom chord, and use Simpson VPA2 clips.  Your sheetrock guys will thank you, because there will be nailing for the tops of the boards.

I want my windows to be higher and if I make it bearing higher up I can integrate a header up into the trusses.
