Windows in CMU Walls - HELP

I'm having trouble getting dimensions of my CMU walls to comply with my window sizes. 

 

Example:

  • 64" wide CMU opening (8" Block Module)
  • 1.5" trimmers
  • .5" RO each side
  • 60" Nail-on Vinyl Window

I want the wall opening to dimension as 5'-4" and the Window Schedule to indicate the width as 60"

What settings do I use in the window dbx to get the walls to dimension correctly?

I have tried 1-1/2" Jamb Width and 1-1/2" Trimmers.

  • Jambs are shown inside the 60" Window dimension
  • Trimmers don't exist in CMU Walls
  • Window shows in Schedule as 60" width
  • Dimension to RO is also 60"

Evidently Chief just doesn't know how to deal with a rough buck (trimmer) in a masonry wall.

I don't think the window is the Issue Joe , you need to set your Dimension Defaults to Rough Opening to measure it correctly...........

 

unless I misunderstand something? as it seems to work for me...though you are correct ....CA doesn't show the Buck/RO Space.....

could be done with a Cross Box but that could be a bit of work depending on the size of the project , but copy >reflect about  helps.
