ok got it, one last small request if i may. is there a way that the block can have a unique color that will stand out. yellow would be the best i think. other than that it is just what i was looking for and i am extremely grateful.

Why not add this to your great routine:
;;; DimPrec.lsp
;;; By Charles Alan Butler 04/27/2003
;;; This routine will flag all dims that have dimension text
;;; over ridden or have a precision greater less than 1/32 .
;;; One or more of the following symbols are placed over the dimension
;;;
;;; Symbols
;;; CHECK = Dimensions that have a precision >= 1/32
;;; S = Dimensions that are STYLE dependent for precision
;;; Circle/ = Dimensions with precision less than 1/32 (0.00000)
;;; SquareX = Dimensions that have Text Overrides
;;; Diamond+ = Dimensions that are rounded off & precision is ok
;;;
;;; The symbols used are placed on Layer "DefPoints"
;;; and sized according to DIMTXT size variable,
;;; or the Text Style of the DIM if it's size > 0
;;;
;;; Limitations :
;;; not designed to work in paper space.
;;; USCS World plan view only
;;;
;;; Revision 04/12/04
;;; Correction for ACAD2000, blocks are created on layer 0 now
;;; Dims selected are visible in space you are working
;;; not All dims & frozen as before
;;; Streamlined code
;;;
;;; Revision 12/17/05
;;; Added the Rounded Off flagging of dimensions that are within
;;; the precision of the style
;;;
;;; Revision 12/20/05
;;; Revised routine to be call by another lisp
;;; Arguments:
