Q - question

ClosestPt - the nearest point on another curve

A - answer Using the freeware utility ClosestPt you can create lines connecting two nearest points on two different 2D or 3D curves (line, polyline, spline, etc.) - i.e. shortest connecting lines.

Download the file ClosestPt.vlx from Download, load it into your AutoCAD using APPLOAD and run it by typing the command CLOSESTPT.

Select the main and the secondary curves and then choose the method of searching for the nearest points. The option Vertices connects the nearest existing nodes (vertices) on both curves - creates connecting lines. The option Point2vertex connects the picked point on the main curve (use the Nearest osnap) with the nearest node (vertex) on a secondary curve. The option pOint2point works similarly, but connects any nearest point on the secondary curve (not only vertices). The given specified precision will be used (an absolute distance tolerance).

The two dynamic option works in the same way - Dyn2vertex and dYn2point, where you can interactively specify points on the main curve and temporary connecting lines are drawn, including their lengths. By mouse left-click you will draw the connecting line as permanent.

The option prEcision will preset the used precision. You can also set it by presetting the LISP variable:

(setq _closestsprecision 0.1)

The usage of the application is illustrated in the video:
