"Yes I can do that but under no circumstances do temporary dimensions function on the non ortho walls."
Seems true - no temporary dimension on a Wall that joins at an angle with another Wall. Revit doesn't always do too well when angles are involved.
What I did below is drag the endpoint of the Walls to make the joint with the angled Wall a right angle, and then the temporary dims become available. However, if you make the dimensions permanent and correct the Walls, the dimensions are lost. There's not much I can contribute here, so I hope this is of some help.
I have found that using temporary model lines can be a great aid to locating or moving objects that are otherwise difficult to snap to or adjust using normal methods.
Probably a pinned reference plane, perpendicular to the angled wall, could be used to control the distance of the door to a corner, with a dimension.
Thanks for the suggestions, still a Revet newbie, I'll try them until I find the easiest. Sure seems like there should be some sort of plascement constraint for doors and windows similar to ACA;s for center, offset, etc., since Revit is purported to be the "best".
Wish List anyone
