STEP Exchange Fixture Matrix

Pick STEP fixtures for part exchange, assembly handoff, and CAD importer compatibility across engineering toolchains.

3 Fixture Rows

3 How to Use This Matrix

Use the matrix when the validation target is a set of variants rather than one canonical sample.

How to Use This Matrix

Coverage

Covers block-part, assembly-exchange, and upstream reference STEP fixtures.
Useful for CAD importers, engineering-tool interoperability, and product-data exchange.
Anchored to manufacturing-prep, CAD exchange, and design handoff packs.
