Log truss


Recommended Posts

I have tried the log truss from the library. I remember I couldn't do much with it so I never went back but maybe I should revisit that.

I figured out how to cut my log to length just by drawing and extruding some polyline solids to subtract from the log.

What puzzles my more than anything is why sometimes I can move to an elevation and click on and rotate objects and sometimes I can't.

After an hour of banging my head against the wall it works and I can't figure out what I did differently.

Also, it would be nice if you could have an option to draw round roof and floor beams.

anyway... off we go.

This just depends on the object type.  In your particular case, for these logs, you basically have 3 different object you would most likely be working with:

1.  A symbol:  These should be easily rotated in any view.

2.  A polyine solid:  Remember that these are only 3D extrusions of a 2D shape.  That means these can only be rotated in the view they were created in or in the directly opposing view since those are the only 2 views the extrusion shape (profile) actually exists in.

3.  A solid:  These can be rotated in any view since they are not connected to a 2D extrusion.  One big limitation is that there is no Make Parallel/Perpendicular since the solid has no actual definable 2D edges for Chief to use for that operation.  This means you must specifically rotate solids using another method (angle snaps for example).


QUICK POWER TIP:  Group (control) select the solid in an elevation view to force it to rotate perfectly perpendicular to that camera.  


There's a lot more that could be said about modeling custom log-work like this.  For anyone interested in a more in depth discussion, please consider contacting me at alaskansons@gmail.com to set up a customized one-on-one consultation session.

      I cannot seem to figure out how to make this exposed gable have the same shiplap siding on it that the house has. I built the patio piece by piece using framing members and added roof planes and ceiling planes then added the gable. Now II cannot figure out how to add siding.

      First post here, this is my first attempt at roof truss. As you will see in the PDF attached the gables that are on the front of the duplex are being supported by the truss that are running in the vertical direction. I am wondering if this is normal as i cannot seem to create truss for the gables on the font of the home. If there is a more effective means of building roof truss for roofs of this style id love to hear them.

      Can anyone tell me why my roof trusses are not showing when I draw them in on this plan? I've watched every video and cannot work them out. The closest I came was getting trusses with vertical studs/gable end style. 
      Uploaded them to online docs due to size: 
      Also, I am trying to show 22mm battens on top of the truss, and attached to the ceiling for the wall plasterboard to attached to (Australian style). Does anyone know how to set this up? see attached

      I'm using Home Designer Pro and trying to overlay perpendicular roofs but cannot find the truss base tool. I assume the program does not feature this tool and I'm required to try and create overlay with poly's. Is there another way and if not, what version of CA would I need to purchase to access more advanced roof tools (I am manually setting roof trusses).

      A lot of my work involves trussed roofs.  After building the trusses, I frame the roof for the facia and varge rafters.  Problem with this is that CA adds ridge boards that don't exist in trussed roofs.  There doesn't seem to be a way to frame without ridge boards or to set the ridge board dimensions at 0.  If there is a work around, I'd love to hear it.
      Also....  Is there a way to frame a roof where one roof California or over frames over another roof.  In my previous CAD, I could trim the bottom of one roof to the top of another and the framing acted accordingly.  This program even added a valley plate on top of the lower roof and below the rafters of the upper roof.  That may be too much to ask for, but one can only  hope.
      Love to hear what y'all have to say.
      Thanks in advance.
