Roof Framer Nominal Sizes

[compusam]

Why does the Roof Framer Tool create the wrong nominal lumber sizes. For example, a 1.5" x 9.25" rafter which should create a nominal 2x10 is shown as a nominal 4x10 in the info palette and in the Framing Member Report. I have checked the lumber size data file in the Plug-ins/VW_Arch folder which has the correct nominal sizes.

You need to go into the Lumber Sizes.txt file (Plugins-VW_Arch-Data) and change it to read (notice I've added the somewhat unusual 3x sizing):

Units Actual Nominal

Imperial 1.01" 1"

Imperial 2.01" 2"

Imperial 3.01" 3"

Imperial 4.01" 4"

Imperial 6.01" 6"

Imperial 8.01" 8"

Imperial 10.01" 10"

Imperial 12.01" 12"

Imperial 14.01" 14"

Imperial 16.01" 16"

Imperial 18.01" 18"

Imperial 20.01" 20"

Imperial 24.01" 24"

Be careful to read the caution heading.

Good luck,

Thanks. That seems to work. Now, of course, I have to "re-set" all of the existing roof framing members to get them to display the proper nominal size? a minor inconvenience.
