I'm opening a DXF file, made with Inkscape, which was saved in Inkscape with "LWPolyline Output.

When I place a Dimension Line in the drawing, to place engineering information onto the drawing, DraftSight shows the Drawing Units in the Dimension Line of course.  The distance in the Dimension Line is shown as 57.  Okay, but can I set the distance to be 5, without scaling the drawing?  If I scale down the drawing I can get the distance to read 5, but  the curves in the drawing become coarse. Thanks.
