Change Summary Tables

Geometry and Cost Engine Changes

The table below contains a row for each geometry or cost engine change. Each row lists the following:

  • Process group to which the change applies
  • Impact level of the change (High, Medium, or Low)
  • Whether the change can or must be disabled using site variables.
  • Description of the change and its impact

Changes are geometry changes unless explicitly labeled Cost engine change in the description.

The entries are arranged alphabetically by process group.

You can use this table to guide you in performing Step 2 and Step 3 of impact assessment (see Impact Assessment Steps). Click on the name of a process group in the first column to get more information on changes for that process group.

(In this release, 2025 R1, there is only one process group with geometry changes: Bar & Tube Fab.)

Process Group Impact Level Can be Disabled? Must be Disabled with Prior CMVs? Impact Description
Bar & Tube Fab Low No No This release continues a series of improvements to the Bar & Tube Fabrication process group to better recognize the intended stock form from which a part is made and to correctly identify all features modeled on the part.

Before you upgrade, review the process groups you use, and identify the ones have that have changes that impact aPriori estimates. Once you have determined whether to accept or disable each High-impact geometry or cost engine change for the process groups that you use, you can upgrade to the new release. If there are no High-impact geometry or cost engine changes, you can upgrade to the new release.

aPriori also recommends that you review the cost model changes as well as the Low- and Medium-impact geometry and cost engine changes for the process groups you use.

All Changes

The table below indicates which categories of change impact each process group, as well as the cost model versions introduced in each of the last four releases.

Process names in the table’s first column link to process-group-specific sections which can help you to perform Steps 3 and 4 of your impact assessments (see Impact Assessment Steps). Each of the sections contains summary tables as well as change details grouped by the following three categories:

  • Geometry or cost engine changes that could impact configured Digital Factories: these are changes that might impact costing even for Digital Factories that use earlier cost model versions.
  • Bug fixes or small improvements to prior cost model versions that could impact configured Digital Factories: these are back-ported bug fixes, which might impact costing for Digital Factories that use earlier cost model versions.
  • Cost model changes that do not affect configured Digital Factories: these are changes that do not affect costings with Digital Factories that use earlier cost model versions.
