Localized Feature: Metric Units

This feature may not be available in all global regions.


  1. Edit /details/st-hdr-gen
  2. Add the line “op_cr_above=      "ST-STUDA1"” for cripples in head
  3. Add the line “op_cr_below=      "ST-STUDB1"” for cripples below sill
  4. Replacing "ST-STUDA1" with "EXECUTE:OP_CR_ABOVE" will run the ADT program that may control when to add cripples to openings.    
  5. Go to System ->Wall -> Framing details and find “ST-STUDA1” and   “ST-STUDA2”.
  6. Under OffsetWidth, you can change the offset. In this case, #SF# is the stud flange and #OF# is a stud offset gap, usually set to 1 or 2mm.

You can check the value of #OF# or the definition of #SF# and #SC# etc from /details/material_specs.
