Mesh Interval Preview

It is sometimes useful to view the nodal locations/intervals on curves graphically before meshing (which can take considerably more time). The command to do this is:

Preview Mesh {Body|Volume|Surface|Curve|Vertex} <id_range> [Hard] [color <color>]

To clear the display of the temporary nodes, simply issue a "display" command. The purpose of the hard option is that only curves that have an interval firmness of hard will be previewed.
