Thanks for the reply, and sorry to not respond simoncbevans, I never got, or at least never noticed, an email that there was a response to my question.
To clarify, I meant dividing it into two, or in some cases, dividing it up into something less than what it is, not necessarily in two tho. I may build a garage door model that is 18’ wide and then have to reduce it to 17’9…I thought there may be a simple way to “cut” 3" off the entire model (1 1/2" per side) similar to how a section plane cuts through a model for section view.
This wouldn’t be a typical garage door most of us have on our homes where I could push/pull the rectangle and make it the size I need, these doors have different types of overlays (Ipe, Accoya, Kebony, etc), with rain screens/drainage planes/furring behind them, all on top of a typical garage door section. All of this overlay material is laid out on the face of the garage door to align with the same material on the house, many times it’s centered on the garage door too, so just taking a certain number of inches off of one end of the door wouldn’t work.
