Have a look at this  :

Just a comment for house type plans have drag a line over walls and it makes the dims. All wall lines auto dimmed, is that what your trying to do rather than pick points. Part of a house package so yes a fee.

Very nice and certainly adding to my library. Have not figured it out yet, but the (princ.. Dimension Distance) on line 60, causes it to quit, vlide highlighted it and runs fine without/commented. Thanks
