static

Builds NURB curves using the specified range of point offsets, as dictated by curvesizelist and curvepointnumbers, in parallel. curvepointnumbers lists the offsets of the points used by each curve MINUS startpt, i.e. they are offsets relative to startpt, not indices relative to startpt. The offset of the first curve is returned, and the rest are at consecutive offsets. All curvepointnumbers must be between 0 (inclusive) and npoints (exclusive).

NOTE: Existing primitives are allowed to be using the points in the specified range already, and the curves being created do not need to use all of the points in the range. However, these cases may impact performance.
