dangnabbit, it looks like I'm going to have to dimension in model space... EEWWWWW I feel all slimey now.
Feel your pain. That is the ONLY allowance we make for modelspace dims. I have gone to coordinates (DIMORD) to avoid placing dims in MS.
I don't think ordinate dims would be very welcome on foundation sections, unfortunately, but that is a good solution I'll have to make sure I don't overlook, if I run into it on steel drawings.
Interesting side note... looks like the same trolls that haunt the Adesk boards today were around 8 years ago, too... guess there are many things that don't get better with age...
