  1. The way Vectorworks has been sizing door rough openings is fundamentally wrong, but could be so easily corrected. Doors are sized by the slab size, such as 3-0x6-8, which would be 3' wide, and 6'-8" tall. The rough opening width would be that width, plus the width of the jamb on each side, plus the shim gap on each side. This much the program has correct. The problem is that Vectorworks only increases the height of the rough opening by the width of the jamb, plus the top shim gap. The reality is that interior doors are built with a 1" clearance at the bottom of the door, in addition to the shim gap and jamb width at the top. The side jambs go all the way down to the floor on each side. This 1" clearance is not deducted from the slab dimension, it is added to the over-all height of the Rough Opening. I have complained about this for years (17 to be exact), but nobody seems to be listening. To get the rough opening sizes correct on my schedules, I have to lie to the program that my door slab is 6'-9", instead of 6'-8". This sends my jobbers into a tizzy, trying to source a non-standard door. For exterior doors, or other doors with a threshold, the threshold thickness is ADDED to the door slab dimension in the real world, not subtracted from the slab size. There is already a button on the Door Settings/Threshold menu that allows you to check the box: "Threshold Under Leaf". In theory, checking this box would ADD the user-set thickness of the threshold to the total height of the rough opening. This should be a VERY simple fix for any software designer, and should not require more years of ignorance. In addition, if no other parameters of a threshold are entered except for a threshold height, this check-box should allow the designer to select the clearance they want under the door slab as a "threshold height", and the rough-opening would be adjusted accordingly. Simple! If our Vectorworks Door designers are unwilling to actually go out and look at a real door, and inquire as to how they are sized in the real world, we need to "show them the door", and find someone who can do the job.
