CAD Data, Parts, Versions, and Revisions

Separate the product objects before comparing the systems.

A caliper, machined blocks, and a partially assembled mechanism rest beside a drafting board in a bright workshop.
Product data gains value when its relationships remain visible at the point of use.

Start with the record, not the feature list

Files, parts, versions, revisions, lifecycle states, and releases answer different questions. Treating them as interchangeable is a reliable way to create confusion later.

That is why the PDM software comparison matrix records only what official material discloses. A blank cell is never treated as proof of absence. It becomes a focused question for a demonstration or technical review.

01

Define the object. Name the part, file, document, structure, or change record in scope.

02

Define its state. Establish who can revise it, who can approve it, and what makes it released.

03

Define its connections. Identify BOM, CAD, supplier, ERP, and exchange relationships that matter.

Questions that travel well

Ask vendors to demonstrate the exact point where a record moves from working state to controlled state. Then ask what remains visible to a collaborator, what is logged, and how the relationship is preserved when data crosses a system boundary. The PDM glossary helps keep those questions precise.

Use the evidence state as a boundary. “Documented” means a source names the capability. “Edition-specific” means the source limits the statement. “Not disclosed” means the public materials reviewed here do not make a claim. “Needs verification” identifies material awaiting a usable primary source.

Put the comparison to work

Before a selection meeting, bring the implementation checklist and turn every local constraint into a question. Before a transfer, use the migration checklist to establish the validation plan. These pages are designed to make the next conversation more specific.
