Most of my 2D drawings eventually end up as cutting files for waterjet system.  It is important that all shapes are completely closed polygons.  Is there a way to find small gaps or overhanging lines in a drawing file without having to zoom in and inspect every single connection point between lines and arcs?  While I do use snap in creating complex objects, due to constant revisioning and editing, sometimes unintentional gaps and overhangs will appear.  I was hoping that Draftsight contained a tool that can check and highlight small gaps and hanging lines.  Baring that, does anyone have a favorite technique that they use for cleaning up their drawings?

Thanks!
