LinkCAD Knowledge Base

Unlike AutoCAD, where you need to hatch areas to created filled surfaces, LinkCAD always fills all closed polygons.

If your areas are enclosed by a series of separate line segments, instead of a single polyline, you first need to connect these lines and close the polyline. LinkCAD can do that for you automatically: when you open such a file, a dialog "Repair Open Polygons" will appear. The first repear option joins such separate lines into a single closed polyline.
