Balloon frame gable end wall to roof plane.

Recommended Posts

I am rebuilding the garage on my house and replacing trusses on the main house. Pretty simple design, but I cam coming into  CA (X15) from a conventional 3d mechanical cad background (Autodesk inventor etc…), as well as a framing background, I don’t think either has done anything for me lol. I think I have gotten over the worst parts of the steep learning curve but I am struggling the most with how to build a full gable wall at the end of the vaulted ceiling before the attached garage. I didn’t realize when I ordered trusses that I shouldn’t use a flat bottom gable there, I get it, it is a hinge point in the wall, even though the garage is on the other side but I want to have no issues with inspection.

Because I have trusses coming already I want to balloon frame the wall to the roof plane and install fire blocking. So far I can build the wall flat topped with a standard gable truss on top(like it was) or frame the wall up to the ceiling plane. How do I do this in CA?

If you want the balloon framed wall to have top plates positioned for upright lookouts, like what is shown here

You might have to edit the framing in the wall.

 

Shown is a scissors truss arrangement inside for 10/12 vaulted ceiling under a 12/12 roof, and 2x6 upright lookouts running from inboard truss to subfacia, the lookouts bearing on the wall plates.

Right. I appreciate the help, but in the wall framing detail window,  the only thing I have managed to do is drag members around. Nothing like setting the angle of the top plates or stud cuts or matching the top to a plane. I am not seeing much from the help menu on framing detail, and I have not found a decent guide that shows manual edits at all.

In the wall frame detail window, use CAD however necessary to help edit your wall, rotating members, aligning them using the parallel/perpendicular tool, editing intersections with the extend and cut tools.

 

Pro tip.  You cannot draw new framing members, but you can use what is there and copy and paste and resize.  A wall that autoframes at say, ten total members, can be edited to have dozens.

 

Use section cuts and then CAD DETAIL FROM VIEW to create CAD you can then copy and paste into your wall detail.  

 

Have at it.  It's fun.

 

Do you have roof trusses?  Did you know that you can do all kinds of editing of the truss chords, webbing, intersections, etc.?  Play around with it all, and learn!

 

The one shown here was heavily edited,  to show the panelizer how we want it built.
