isPlanar MethodStatic
Check whether or not the curves are planar, and if so, return a localToWorld frame.
isPlanar(curves: MultiLineStringDataVariant | AnyCurve, options?: PlanarColinearOptions): undefined | Transform
@returns localToWorld frame T for coplanar curves, or undefined if they are not coplanar.
T satisfies:
T.originis in the plane.T.matrix.columnZ()is the plane unit normal (or its negative).T.matrix.isRigid()returns true.T.inverse()is worldToLocal; apply to input geometry to rotate it into the xy-plane.
| Parameter | Type | Description |
|---|---|---|
| curves | MultiLineStringDataVariant | AnyCurve | input geometry: curves or points. |
| options | PlanarColinearOptions | bundle of options. |
