Pointstring is a LightWave Modeler plugin, found under Tools/Custom, that will connect the points you've selected with 2-point polygons. This eliminates the past method of selecting two points, pressing "p", deselecting the points, selecting two more points, etc., for as many polygons as you want. To use it, begin by selecting all the points in your chain, in order. Then, run Pointstring, and the points will be connected, in the order you selected them, by 2-point polygons.
Tutorial
Let's make a lightning bolt with Pointstring.
Begin by opening Modeler. Go to the Polygon menu, and choose
Points. Put down some points at random, in the general shape
of a lightning bolt:
Next, go to the Tools menu, and under the Custom drop-down
list, choose RealiTools_Pointstring:
...and now you have your lightning bolt geometry! A lot easier than the old way, huh?
