TRUSS HEEL HEIGHT not showing even after I rebuild the roof.

[cjanderson66]

I don't do trusses very often and now I have a project in which we are going to do trusses.  My problem is that I have drawn my roof, called out trusses with a heel height of 12" but when I frame the roof, the trusses do not show a heel.  The lower cord is still sitting on the top plate with no heel.  I go back and look at all the videos but they are different from X17.  I also have no way of checking the box for retain manually drawn roof planes either is always wants to rebuild my custom roof planes.  Am I missing something here?

Show us a truss from your truss detail page.  Zoom to the heel and draw the heel height.

We simply take the roof planes and shift them up 12" in elevation (transform/replicate +12" z axis). The webbing doesn’t represent a true truss structure anyway, so relying on Chief’s generated web design just ends up displaying something inaccurate. While you can go into the truss specifications and adjust settings like “energy heel” and so on, you’re still modifying an automated web layout that’s only meant to be illustrative...not structurally correct. It’s not worth the extra effort.

if it is an auto generated roof, and you specified heel height at 12", it should build them like that, although I typically have to build all framing to show that, as I have auto build shutoff.

 

If you have one or more manual roof planes, when you build the roof from the build roof dialog, make sure the check box is off for the edited and manual. CA will build an auto roof over a manual roof, so you may have two roofs in the same(x,y plane) location. You will then need to delete the auto roof.

 

To adjust the manual roof planes, as johnny says select the roof planes and use the TNR box to alter in the Z direction

1. The bottom of the bottom cord IS the rough ceiling (just like a ceiling joist) and it is always on the top plate.

2. Gene's image below shows the minimum heel height.

3. For a 12" heel height, you would make that number 12", not raise the roof 12".

4. The easiest way to do this regularly, like most things, is to set up your defaults correctly before you build your roof planes (including ceiling heights and roof structures).

This has the limitation of only one heel height globally. If for instance one is doing an addition, and the customer wants a heel height of 12" for the addition, but the house only has 4" heel height, you will have to adjust either one or the other manually..or perhaps although I have not tried, build some, mark them as edited, then build some more with a different heel height. I find it simpler just to set the heel height for the most roof planes that have the same heel, and then TNR the others to the desired heel height,

 

The other example is an unheated attached garage. It does not need the heel height for the insulation required here for the living space, and IMHO, a garage starts to look odd with high heel heights. As such I always set the garage to a different heel...manually

That's what I typically do.
