Attic trusses missing bottom chord


Recommended Posts

I'm trying to generate attic trusses over a garage and they are missing the bottom chords.  The two end trusses seem to display correctly, but all the field trusses are missing the bottom chord.  The field trusses were generated by copying the end trusses using the place copies at intervals while dragging tool.  The non-attic trusses over the second garage generated just fine, so I'm not sure what I did wrong here.

Eric, thanks again for your help, the attic wall trick looks to be what I need.


Where did you find that info?  I created these following the steps outlined in the help file here:    Any ceiling joists present were generated by the "build attic truss" command, as I just drew a truss using that command per the KB article and then placed additionals using the interval copy tool.

      I would like someone to help me set up a flat roof on my plan.  There are three ceiling heights.  The flat trusses would be constant height - 4 ft.  So, there would be three respective roof heights, each separated with a parapet wall.  I then also need to get the wall framing and new roof framing to all be correct and show up properly.
      If the person that responds is qualified, I would also like to generate a framing plan.   I would like to get responses from anyone that is interested before sending my current plan.  But for now, I can send a picture of what the house looks like (minus the roof/truss system).
      Thank You.  Philip

      Is it possible to create a bi level single open web floor truss?  I have a 6" step down shower in the middle of a truss span and cannot create a single truss to show the recess for the shower floor.  Don't know if the x12 can automatically create this or not or if it is possible to manually alter the floor truss.   
      I did create a room for the shower with a -6 floor elevation and tried to draw a truss but is creates a 0 floor elevation thru the shower.

      Hi there! I am working on a plan (which is attached) for a garage that is 24' wide by 36' long and can not be taller than 18' and trying to get a "bonus room" made out of the trusses vs. making a true 2nd floor. I would like the main floor to have 9' walls so I can have a garage door that is 8' tall vs the standard 7'. I've watched multiple videos on how to create the space above the garage but cant seem to get it just right. The roof pitch I want is either 5:12 or 8:12 NOT 12:12 I have found the 12:12 is too tall and gets the builder up wards of 20+ feet, which I can not build taller than 18' for a detached garage. Exterior walls are 2x6. I got to a point where I did do the 12:12 pitch and made the truss for there but added the 2nd story and having the roof ignore the 2nd floor then placing two walls from front to back to create attic spaces, but when I try a different pitch then it goes away and cant get a truss to work right. I need to show truss specs for this as well. The "bonus room" can be from 7-8' in height for head room and is mainly for storage and a light duty use like a hobby room of some sorts.
      Also when I build an foundation it shows the doors below the walls, why does it do that? The garage is going to be on a 4" thicken slab and the foundation footing is going to be 6"x12".
      Any tips/help would be appreciated. I am using CA X10.

      I have a general question regarding roof trusses and attic walls.  
      If I choose to raise the roof plane then an attic wall is created.  Automatically this wall is a copy of the wall below, typically it will have drywall on it...which is not needed in the attic.  So...I create a new "attic wall" type...without the drywall.  However, if I will be using roof trusses with an "energy heel"...what happens to this "attic wall"?  
      As you can see from the framing perspective view...the attic wall does not show....except at the gable ends.  (I have attic walls turned on).  Does the use of "roof trusses" override the attic wall?  I'm wondering if the materials for the attic wall are still being calculated.  Also...the attic wall does appear in the cross section view.  
      Needless to's a bit confusing.

      I have input the floor plans for a one story residence I measured yesterday. The house has a truss roof.
      It's a simple L-shaped floor plan with the garage sticking out in front of the house. 
      I am running into 3 problems. 
      1. Where the garage roof California frames over the top of the house, the rafters are not showing correctly.
          Chief is only showing small pieces of the rafters and are not continuous from the ridge down to a perpendicular
          rafters below. How do I get the California framing to show correctly?
      2. The blocking between the rafters are not sitting on top of the double top plates. They are places off of the wall.
           How do I get the blocking to be placed on top of the double top plates?
      3. The blocking between the rafters is also showing as 2 blocks between each truss. How do I get it to show only
          one block between each truss?
      Any help would be greatly appreciated.
