High_Number_of_Control_Points_in_NURBS_Surface

This check verifies whether the number of control points on a surface segment or in one parameter direction exceeds the value specified. If so, the model is considered as incorrect.

Note: The check verifies every surface with control points. A check on last modifications is available for this check.

Context

The quality of solid bodies depends on the base geometry, and cannot be modified directly. If a surface has too many internal control points, the degree of the surface or curve segment is too high.

The higher the polynomial degree, the more complex is a curve. Surface segment with high polynomial degree are likely to become wavy.

Designing a very wavy curvature with a low polynomial degree requires a greater number of segments. At low precision, the transitions between segments can become discontinuous, and kinks can appear.

Check Information

Check Details Description
Applicable to: PartFeature
Automatic Solution:
Check Parameters:
  • MaxNumberOfCtrlPointsInParamDir: Integer type

    Specifies the maximum number of control points allowed in the U or V direction of the surface.

  • MaxNumberOfCtrlPoints: Integer type.

    Specifies the maximum number of control points allowed on the entire surface.

    The value corresponds to the product of the number of control points in the U and V directions.
