GeometricConstraintData Class¶

class NXOpen.Features.GeometricConstraintData¶

Bases: NXOpen.TaggedObject

Represents Geometric Constraint Data class.

This class acts as a container of various types of geometric constraints such as position(G0), tangent(G1), tangent magnitude, curvature(G2) and curvature derivative(G3). An array of objects of this class may be used to create a curve. Not all features support all types of constraints. For details of the supported types by a feature, refer to feature documentation. Position is a minimum required element of **NXOpen.Features.GeometricConstraintData</b>.

**NXOpen.Features.GeometricConstraintData</b> can be specified as automatic or fixed type.

Automatic type - When a point (G0) is attached to an object such as curve or a face, constraint types such as tangent, curvature or curvature derivative can be automatically inferred from the attached object. In this case the tangent direction is determined by some scheme decided by the feature. To specify automatic type NXOpen.Features.GeometricConstraintDataAutoConstraintType and NXOpen.Features.GeometricConstraintDataParameterDirection are necessary.

Fixed type - To specify **NXOpen.Features.GeometricConstraintData</b> as a fixed type, the actual objects representing different types of constraints such as NXOpen.Direction for tangent, NXOpen.Scalar for tangent magnitude or NXOpen.Offset for curvature or curvature derivative are specified.

To create a new instance of this class, use NXOpen.Features.GeometricConstraintDataManager.CreateGeometricConstraintData()

New in version NX5.0.0.
