Problem statement:
Inventor currently does not provide a structured PMI representation for general manufacturing requirements that apply to a part, including:
- General tolerances for unspecified dimensions, e.g. DIN ISO 2768-cL
- Edge treatment requirements, e.g. DIN ISO 13715
- General surface finish requirements, e.g. Ra 6.3, no material removal
Today, these requirements can only be represented as general notes in the Inventor model. While this makes the information human-readable, it does not provide a semantically structured representation that can reliably be consumed by downstream manufacturing systems.
Requested capability:
Ability to define these general manufacturing requirements as structured, machine-readable PMI directly within an Inventor IPT/IAM model. The information should be accessible through Inventor's PMI/MBD data model and available to downstream applications and interfaces, rather than being represented only as free-text annotations.
Expected workflow:
Inventor IPT/IAM → structured PMI/MBD → downstream manufacturing application (e.g. Fusion CAM) → automated interpretation during manufacturing preparation.
Business value:
A more complete model-based definition and manufacturing workflow. It would reduce manual interpretation and transfer of manufacturing requirements, improve data consistency, reduce manufacturing preparation errors, and support an end-to-end digital thread from engineering to manufacturing.
Key requirement:
The important aspect is not simply displaying these requirements in the 3D model. They need to be represented semantically/structurally so that downstream software can identify the type of requirement and its value programmatically.
