This program is an AutoLISP routine that allows you to continue drawing Polyline, 2D polyline, 3D Polyline, MultiLine, or Line starting from the selected end. In effect the user gets an object lengthened by the segments he adds. Works also in UCS. When the user closes a polyline while drawing, the program adjusts the last segment's width to match the botch start and endpoint.
Read the General Usage Instructions and see a video example to learn how to use it. A free trial version is available to download at www.autolisps.blogspot.com.
