Detailed Description

See also:: Class NURBSPoint.

Description:: This class is available in release 2.0 and later only.

This class is used to create a dependent point at the intersection of two curves.

All methods of this class are implemented by the system.

Data Members:: protected:

NURBSId mParentId[2];

The ids of the two parent curves.

int mParentIndex[2];

The indicies of the two parent curves in the NURBSSet.

BOOL mTrimCurve[2];

Indicates the point that is constrained to the curve may be used to trim the curve.

BOOL mFlipTrim[2];

If TRUE the curve is trimmed from the point towards low parameter space. If FALSE the curve is trimmed from the point towards high parameter space.
