Roof Drawings need Projections from a roof plane

Recommended Posts

So here I am again, back at the fountain of information.

 

A contractor is asking for flat projections of roof plans to assist his carpenters in laying out the rafters.  

 

I can see how to do elevations, and I can see how to do plan views, but is there any way to do a skewed plan from horizontal projection or section for that matter?

Doug,

 

You could try File...Print...Print Model...uncheck everything except Roofs.

Print to .pdf and then import the .pdf back into Chief.

You should end up with something like this:

Doug, I'm lost...i've never heard of the type of plan you're suggesting.

 

If a contractor asked me to provide "flat projections" i would take that to mean basically like a truss diagram except for rafters.  Something kinda like below but for every "rafter" segment just like a truss package would include.  I have had framers ask for this before.

 

I can't see how what you are describing would help them.  Something like this at every rafter - depending on roof complexity - would.

Glenn,

 

The idea here was a projection of an individual roof plane.  Just imagine rotating the house so that you are perpendicular to the surface of the roof.  That is what the contractor is looking for.  One could then directly scale rafters along a ridge.  This is a hip roof, not a gable roof.  So he is looking for a rough cut list for each hip rafter.  I see his point actually.

You don't need a true projection to do that.

Build framing and get the length of the hip through it's dbx, or the Material List.

As Glenn and Johnny already pointed out, there are several other ways to get that type of information.  In addition to what they said you can also use a framing schedule or a custom macro solution.  If however you still really want the skewed projection you speak of, you can do this...

  1. Turn off all layers except those that you actually want to show
  2. Convert the whole plan to a symbol
  3. Rotate the symbol onto its side using the Symbol Specification Rotation settings
  4. Create a section view for each roof plane (may require rotating the symbol more than once depending on the model)

You could also optionally create separate symbols for each and very roof plane using layer settings, the Delete Surface tool, or by copying and pasting each individual plane to a blank plan.   You can then do the same thing I went over above...Rotate the symbol and then just use a section view.

      Hello, I’m needing help lowering the roof. I’m trying to make a 50x80x16 shop with the pitch lower than the default gable height. I’m new to this and I’m hoping this software will help build our dreams on our farm. I want the look of the attached photo with the front being the 80 ft side.

      How do I put a roof return on this roof? Can't find a video about it anywhere on the Chief Website... is there another name for it?
       
      See attachment, and where I drew in black.

      I'm using X11 premier on a mac -- I have an exterior garage wall (with a centered garage door) and a gable end -- I'd like to split the attic wall of the gable end into 3 parts -- the central region above the garage door, and the left and right, to have a different material above the garage door.

      I have Default Settings > Roof > Auto Rebuild Roof set to Off
      I have Default Settings > Framing > Automatically Build Floor and Ceiling Framing Off on all framing types.
      I have Default Settings > Walls > General Walls > Auto Rebuild Attic Walls set to Off

      If I delete the roof and ceiling planes with Build > Roof > Delete [X] and then use the Build > Roof > Build Roof ... dialog to rebuild the roof and attic from scratch -- I leave the Auto Rebuild Roofs set to Off, to be clear -- and then edit the resulting gable roof on the attic layer, I can split it twice to produce the three separate wall sections, but once I change the exterior material on any of the sections, the three wall segments get replaced with a single wall again.  The new wall has my selected material, but that does me no good as I need the distinct secgments.

      Anyone know what setting do I need to turn off to maintain the manually edited gable end?  Or is this a mac bug?

      Or, barring that, does anyone know what approach will let me give the desired finish detail (attached a pic of a freehand elevation)?
