I am looking for a solution. I have CA X10. I am fairly new to the software.


I have a old house I am trying to replicate on a plan. The first floor has 2"x7.75" floor joists that are connected directly to the sill plate which is a wood block 5.75"W  x 7.75"H. 

The wood block sits on top of a 8" CMU foundation wall.


There is a porch outside with the joists connected directly to the sill as well, BUT, it has a double rim joist (2) 2"x7.75"


I tried 2 things:

1. I set the foundation to have a sill plate of 5.75"W  x 7.75"H. and the floor joists build on top of the sill.


Question 1: Can I tell the floor joists to build with the sill?


2. I set the foundation to have no sill and set the floor framing rim joist to 5.75"W  x 7.75"H.

This worked accept for 1 thing BUT: when I build the porch outside it has a rim joist of 5.75"W  x 7.75"H


Question 2: Can lock the framing for 1 or multiple rooms on a floor so when building new rooms on that floor they have different floor framing?


My solution is to set the foundation to have no sill, and manually place the sill on the foundation wall using a floor beam and build the floors.


Am I doing this all wrong or am I on the rite track?


Thank You!

One setting that may help you out a bit is in Foundation Defaults :  "Hang 1st Floor Platform Inside Foundation Walls"  but you will likely still have some editing to do after that.


Also when posting detailed questions it really helps to include some screen shots and in situations like this the .plan file can be quite helpful as well.

Yeah,  always helpful to post some screen shots and post the plan file.  Some of the old time helpers are lacking the energy to ferret out what you want so the easier you make it for them,  the more they will help.

Chopsaw's large sill plate issue is similar to mine.  His seem to align perfectly with the foundation wall but ever since I finally got the Sill plate to show up as USED in layer display I have not been able to get the Foundation wall, the Sill plate and the Wall framing/Floor joists to line up.




The second issue is that the floor joists have a 2" x 6" notch to rest on the Sill plate. 




So far I have only discovered how to put Floor joists either on the Sill plate or Hanging in between the Foundation walls. Is there a way to

put a notch in the Floor joists to rest on the Sill plates.


Thanks for any help,

      I am having an issue creating floor/ceiling framing for rooms on both first and second floors. I appreciate any light that can be shed on this error/Question message.
      I have attached a PDF of a screen shot of the message.
      Best Regards,

      I have difficulty troubleshooting WHY my ceilings and floor framing isn't generating when Auto Build Framing is run. I have checked all the room default settings as well as the framing default settings and all seem to be set correctly for my project (2x10 floors, 2x6 ceiling). The plan file I am working with was purchased from a Designer who worked on the house several years ago and assembled the As-Built model. That said, This is a recent situation with the framing. a week ago Auto Build Framing worked fine.  What may I be overlooking?
      One other note: this issue appears to only happen where the Second floor exists. Main floor rooms with just attic space above, DO generate ceiling and floor framing.

      I am working on an addition and just want to show the new framing; walls (the easy one) floors, ceiling etc., Can this be down automatically with specific settings or does it have to be done manually?

      I had a problem aligning the Foundation, the Sill plate and the Framing.  The problem started after I finally got Sill plate to
      appear as Used in Layers. After more than one day of no progress I decided to restart and build a new plan from scratch.
      I went through defaults on the new plan repeatedly before starting any drawing. Sill plate is not yet indicated in layers as Used. (For that matter, Foundation is not yet indicated as Used) The Framing has not started yet, but there is already a lot of difficulty just aligning the foundation to the first floor.  When the Foundation wall is being traced over the Reveal floor outline, the square Endpoint indicator aligns the Foundation wall to roughly the middle of the Reference wall, not the exterior edge.



      I tried re-sizing the foundation wall lengths to the correct dimensions, after re-sizing the two floors are the same size but are still not aligned with each other.  (I started by extending the first wall in both directions. Each subsequent wall was extended away from the first by using the arrow indicators for dimension re-sizing)
      I tried applying a 5" Foundation offset in the Foundation wall definition.  The square Endpoint continued to register ~5" away from the exterior edge of the first floor Reference wall line.
      I tried applying a 5" Bridge ledge in the Foundation wall definition. The Foundation wall continued to mis-align with the reference wall above.


      If I try to manually move the foundation wall, CA won't allow a perfect overlap.  Maybe this has something to do with snaps.  The snap settings are all default, I've tried to understand snaps but so far not enough to attempt changing anything.
      Any help greatly appreciated,

      I am just working on a masonry garage design, and have been held up trying to figure out some details. One is for steel lintels that I am putting over the openings. The closest thing that you can use as a header type is a steel-box but I will be using steel angle. The header column shows the dimensions including the length of your lintel but only gives 1.5" on each side of the opening. Is anyone familiar with a way that I can change this to more? Otherwise, I will just remove that column and leave a note in the comments.
      Second issue: When you pull your cross sections from a CMU building, it shows your trusses sitting right on the block. For now I have manually drawn my plate in with an anchor but I was curious if there is a way to do this as well?
