In Creo Parametric 11, you can now control the reference type for boundary surface references in Seed and Boundary surface selection.

You can use the new option, Consider as strong references, to mark boundary references in the surface collection definition as strong references. If these references are no longer present, Creo will report them as missing strong references, and the surface collection will fail.

If this option is not selected, boundary references are considered weak references, consistent with behavior prior to Creo Parametric 11.

You can define the default behavior in the Creo Parametric Options dialog box under Creo Parametric Options > Global > Selection > Surface and Chain Sets. By default, boundary surfaces are now considered strong references starting with Creo Parametric 11.

Strong and weak references behavior for boundary surfaces each have their pros and cons. Previously, you could not adjust this behavior according to your preference.

  • New option: Consider as strong references
    • Weak (existing behavior)
    • Strong (new)
  • Controls regeneration behavior
    • When set to strong, if boundary references are missing, the surface collection will fail even if it could otherwise return a surface collection result
  • Configuration option:
    • default_boundary_refs_strong yes*, no
    • Also accessible from Creo Parametric Options > Global > Selection > Surface and Chain Sets

Benefits:

  • Improved flexibility to control regeneration behavior according to your preferences.
