Geometry or Cost Engine Changes that Could Impact Configured Digital Factories

The following changes might impact costing, even for Digital Factories that use earlier cost model versions.

  • STEP Assemblies: This release extends the Multi-Body Options setting to apply to STEP assemblies containing solid bodies.

    Before aPriori 23.1.3, aPriori always interpreted a solid body within an assembly STEP file as a part. Beginning in 23.1.3, aPriori behavior changed unintentionally, due to a change in underlying 3rd-party libraries. As a result, solid bodies defined within an assembly STEP file were neglected and were missing from the aPriori scenario. There were no options available for users to change this interpretation.

    Now, in 24.1.2, the interpretation of solid bodies in STEP assemblies is controlled by the Multi-Body Options dialog. The first option, Keep Free Bodies, now applies to STEP assemblies that contain solid bodies. Select (check) this option to import these solid bodies into aPriori as part scenarios. This is consistent with aPriori’s behavior when it interprets native NX assemblies containing solid bodies.

Cost Model Changes that Do Not Affect Configured Digital Factories

The following changes do not affect costings with Digital Factories that use earlier cost model versions. The changes are available only in the latest cost model version.

  • Machine Power: The 2024-09 Regional Data Libraries include updates to machine rated power values. These changes have a negligible impact on direct overhead costs. In a test set, overhead costs decreased a maximum of $0.03, compared to the previous release.
