You can control dimension line properties including color, lineweight, and spacing. 
 You can control several aspects of a dimension line. You can 
- Specify color and lineweight for visual effect and plotting 
 
- Suppress the dimension line or, if the dimension line is broken by text, one or both halves 
 
 
- Control the spacing between successive dimension lines in baseline dimensions 
 
 
- Control the distance by which the dimension line extends beyond the extension lines for architectural tick (oblique stroke) arrowheads
