you have several choices.
First, if you use a door PIO then you can use the offset insertion mode. This can be used to offset the window or door a specific distance.
Second, You can control the insertion point. It can be centre of the object, left side or right side. If you add trims to this before you insert the door, then it measuses to the edge of the trim. If you turn the trims off, it measures to the outside edge of the jamb.
Third, you can insert the door or window with the trims turned on (to tmake it easier to position) then turn the trims off if you don?t want to see them.
Fourth, you can make the object into a symbol and set any insertion point that you want and then use the offset insertion mode to place the door or window.
