How to highlight polyline nodes and segments?

A - answer When editing or checking a DWG drawing, or when using objects snapping to polyline vertices, it may be neccessary to temporarily highlight nodes (vertices) of a 2D or 3D polyline, display the drawing direction and type (straight, arc) of its individual segments.

This functionality is available in the free LISP utility CADstudio HltNode. Download this add-on application from, load it with APPLOAD and run it by typing the command HLTNODE. After you select a polyline, all its vertices will be marked with red arrows (first vertex in green) and arrows pointing in the drawing direction will be drawn by its segments (shorter and differently colored arrows by arc segments). Size of these symbols is related to the current screen size. Display of these marks is just temporary, they will dismiss on the next screen redraw (F7,F7 or REDRAW).

See the VerticesBlk utility for permanent auxiliar points placed in polyline vertices.
