The fillet command enables users to create a rounded corner (or fillet) between various entities such as lines, polylines, arcs etc. by extending them, then trimming. It is well worth experimenting with it in gCADPlus. Filleting can save much editing time. For example, it can be used to square off a corner in one single click without the need for a double trim. Alternatively, the resultant corner can be given a radius.
