Truss issue

Recommended Posts

I have a condition were a attic firewall needs to sit between trusses.  I'm trying to get the truss to not be fully across the wall below which is a double firewall.  When I drag the end of the truss where I need it the truss simply snaps back to the original size.  When I select the truss not to rebuild, and then move the truss end back the shape of the truss isn't correct.

 

I also included an example.  What is in red is what I want the truss to build to.  In blue is the truss im getting snapped to.

 

Any help is appreciated.

Not quite getting the whole picture but you can adjust the truss envelope in cross section and you can do almost whatever you need in custom framing in the truss detail if you unlock it.  I assume you dragged in plan view.  Hope that helps a bit.

Thanks Chop - that worked.  I was trying to open the truss profile thinking to edit it there and it wasn't working.  Its a section I needed.

That is my bread & butter, but don't forget sometimes you need to move timbers (2x) to finalize a truss and that is accomplished with the profile. 

 

Also if I want to show a truss cantilever, I'll break the profile polygon (in section) over top of the cantilever wall.

JP,

How are you getting those truss connector plates? (Manually?!)

 

If you are talking about the illustration that is just a 2D illustration from an online source I referenced for firewall assembly design when you have to break the span direction of a truss.  Is that what you mean?

 

I will say i've hired Michael to do some modeling and he does the connectors and hangers all in 3D which are pretty cool.  His models are incredibility detailed.

Okay. I assumed it was something you drew in Chief.
