How to create Parallel Chord Truss

Recommended Posts

Hello Everyone,


The builder I work for uses Parallel Chord trusses for the majority of their projects and I cannot figure out how to get the software to correctly display this system. I have attached a jpg of a section drafted in different software showing what I am trying to accomplish. Currently I am just using I-beam trusses to mimic the size of this system but they are not getting trimmed to the walls and stick out past the walls in section and elevation view. This does not look very professional and I would really like to be able to properly display the system we are using.


Can chief do this? If so how?


Thank you in advance for your help.

It is a spot of bother and I haven't needed to do it since version 9.5 but you merely have to unlock the Truss envelope layer in Display options and then you can, with patience reshape a truss envelope and edit the chords anyway  you wish. You might want to carefully read the section of the Reference Manual regarding truss editing first.

you need to draw a roof plane and ceiling plane in the room you want a parallel chord truss for.

then draw a truss manually.

the webbing will go between the 2 as it should.

Trusses build to whatever shape you have set between your ceiling and roof plane (underside).  As Bernie mentioned, make a ceiling plane parallel to the roof plane but up (z) 3'-6" if your picture is correct for the depth of the truss.  You can also custom edit a truss - and there is a video on that.

      Summary: We're creating a vaulted tray ceiling in a house that started as a double-wide mobile home. I want to model the existing "trusses" so that I can figure out how to do the rafters to frame out the new ceiling. I cannot figure out how to do this though. 
      This house started out as a double-wide mobile home. It's been remodeled several times, huge portions added, walls rebuilt in places, rooms moved, walls removed. But the roof structure through the middle of the house is a 2.5/12 pitch, framed as follows: 2x2 rafter, 2x2 joist, 16" OC, with 12" pieces of 1/4" paneling used as gussets every 12". The tall wall has 1/2" plywood as a ridge beam.  I attached a drawing that shows each side. 
      I tried changing the rafter and joist settings to 1.5" x 1.5", but it insists on building roof framing with 6" rafters floating above the walls, and framing the tall wall with studs that are in the room wall below. 

      I tried to manually draw the framing in like the CAD detail drawing I attached, but I can't figure out how to rotate the 2x2 rafter to the 2.5/12 pitch angle. I figured I'd draw one "truss" manually, and then replicate/copy it across every 16". But after about 6 hours (admittedly I'm new to this app) I still couldn't figure it out. 
      I put both sides together, and added the 2x6 rafters and 2x4 cross brace. Then we plan to cut the trusses back flush with the rafters and brace. The wall will be coming out of the middle. There's no code here, unincorporated county, so no building inspection to send this through.
      Is there a way I can take this CAD drawing and use it for the actual rafters - extrude the 2D shapes into 3D?

      I've created a cathedral ceiling over a living room but cannot get the trusses to span across all of it.  Per the attachment, they begin properly at the back of the living room, cross the peak of the cathedral ceiling, then stop at a roof pitch change.  I've tried rejoining the roof planes and ceiling planes but am not able to figure out why the truss stops at the roof pitch change.  My truss top chord is 7 1/8" for insulation purposes. Any ideas or suggestions?  I will send the plan file if needed.

      There are a lot of ways to make a column like this using the tools Chief gives us...this is a method I use.  Hope it helps...
