Explicit Specification of Intervals

The density of edges along curves is specified by setting the actual number of intervals or by specifying a desired interval size. The number of intervals or interval size can be explicitly set curve by curve, or implicitly set by specifying the intervals or interval size on a surface or volume containing that edge. For example, setting the intervals for a volume sets the intervals on all curves in that volume.

The commands to specify the number of intervals at the command line are:

The first command above sets interval counts. When setting interval counts for surfaces, volumes, bodies and groups, an intervals firmness of soft is assigned to the owned curves. When setting the interval count for a curve, a firmness of hard is assigned.

Interval size may be specified as well; the interval count for each owned curve is computed by dividing the curve's arc length by the specified interval size. Interval size commands always assign a firmness of soft to the specified entities.

The user can scale the current intervals or size with the following commands. Scaling is done on an entity by entity basis.
