What's new in DataCAD 14
DataCAD 14 includes a new property called KnockOut which you can use to hide
information that is behind the portion of the drawing you want to appear
unobstructed. This feature is particularly useful when adding text or
dimensions which you want to display over hatching. You can apply the
KnockOut property to Text, including MText and PText, Associated Dimensions, 2D
Arcs, Circles, and Ellipses, Polylines, 3D Polygons and Slabs.
