Gaps - how to find loose ends on lines in a DWG?

With the freeware LISP utility Gaps you can mark spots on your DWG drawing where line ends do not precisely match (undershoots/overshoots, no osnap).

Download the Gaps.vlx file from Download, load it into AutoCAD with APPLOAD and type the command GAPS. Specify the precision - how far (in what distance) are the line endpoints considered as near, loose ends, then the diameter for marker circles (red circles in the GAPS layer) and then select the inspected lines (Lines, Polylines, Arcs, Splines) in the currently displayed part of your DWG drawing. The command marks suspect locations and you can then verify (an possobly fix) them one by one using zoom.

The next run of the Gaps command will erase previous markers (the GAPS layer).
