The Divide Surface and Unify Surfaces features have been enhanced for improved functionality:

  • Enhanced Handling of Enclosed Contours in Divide:
    Regions fully enclosed within, but not intersected by, the defining sketch projection or a single closed chain are now included as part of the new surface for each selected surface.

Previously, only the surface regions intersected by the sketch projection or chain were included when working with surfaces containing multiple contours or regions.

This enhancement ensures more predictable and intuitive results, better aligning with user expectations. Depending on the scenario, it may produce slightly different outcomes, especially when using the flip option.

◦Creo 9.0

1.Enclosed contours that do not intersect the sketch

In Creo 9.0, there is ambiguity. The contours inside the closed sketch that do not intersect the sketch are not included in the geometric result, and remain with the original surface.

◦Creo 10.0

1.Enclosed contours that do not intersect the sketch

In Creo 10, the results are predictable. All the contours inside the sketch are included in the geometric result, whether or not the contours intersect the sketch, and are included with the new surface.

Note that only the surfaces that have the same surface ID will be included when the sketch passes through any of the contours in that set of surfaces with the same ID, regardless of the method of selecting the surface to divide.

•More stability in IDs

For typical cases, the surface ID of the surface created by a Divide Surface feature remains the same upon regeneration when dimensions change, leading to increased stability of the model. This applies to Divide Surface features created in Creo 10.0.

•Improved support of Dividing Edges in Creo Flexible Modeling operations

The behavior of dividing edges is more predictable during modeling operations and Round/Chamfer Recognition.

The support for dividing edges in Creo Flexible Modeling operations, such as Move, Offset, and Modify Analytic Geometry, has been enhanced with the following behaviors:

Behavior of Dividing Edges:

  • Unchanged Surfaces:
    Dividing edges that are extended or trimmed during operations will remain, provided they stay within their original domain of definition.
  • Transformed Surfaces (e.g., Move/Offset):
    Dividing edges are treated as rigid edges and are transformed accordingly.
  • Rounds:
    Dividing edges on rounds are automatically removed during operations.
  • Tangent Neighboring Surfaces:
    Tangency conditions are not propagated across dividing edges.

Modifications to Geometry on Divided Surfaces:

  • The system attempts to restore, trim, or extend dividing edges within their original domain of definition when geometry is modified.

Rounds and Chamfers Improvements:

  • Recognition of rounds and chamfers with dividing edges is now supported.
  • Editing or recreating rounds and chamfers during Flexible Modeling operations is supported. However, dividing edges associated with rounds and chamfers are automatically removed.

Additionally, dividing edges on rounds, chamfers, or tangent neighbors to modified surfaces are removed during Flexible Modeling operations.

Unify Surface Improvements:

  • The restriction on unifying surfaces has been removed, allowing all mathematically identical surfaces to be unified, regardless of their origin.
  • Surfaces created through methods other than the Divide Surface feature are now eligible for unification. Legacy features are upgraded to the new behavior upon Edit Definition.
