# NURBSIsoCurve : NURBSCurve

This class defines a dependent Iso (isoparametric) curve. U and V Iso curves are dependent curves created along lines of constant parameter value of a NURBS surface.

Constructors

    NURBSIsoCurve [<property>:<val>]...

Any of the object's properties may be set via optional keyword arguments on the constructor.

    getObject <nurbsset> <index>

Properties

    <nurbsisocurve>.parent : integer

The parent surface by NURBSet index.

    <nurbsisocurve>.parentID : integer

The parent surface by NURBSId.

    <nurbsisocurve>.dir :#U, #V

The direction of the iso curve, either #U or #V.

    <nurbsisocurve>.parameter : float

The parametric position in the range of 0.0 to 1.0 in the given direction on the surface at which the iso line will sit.

    <nurbsisocurve>.trim : boolean

If true , trims parent surface at the curve.

    <nurbsisocurve>.flipTrim : boolean

The state of the trim flip toggle. This controls which portion of the surface is trimmed.

    <nurbsisocurve>.seed : point2

The seed location is a UV position on the parent surface.
