This command removes hard breakline description tags from
polylines. These tags are used by Triangulate & Contour to
identify polylines as hard breaklines. Contours are not smoothed as
they cross these hard breaklines, even with contour smoothing
turned on. This routine untags polylines so that contours are
smoothed across them. If contour smoothing is turned off, hard
breaklines have no effect.
Select polylines to remove hard breakline tag from.
