Assign material and check mass in PartMode
Assign materials to PartMode bodies and verify revision-bound volume, mass, center of mass, inertia, and geometry health.
Calculate mass properties without presenting placeholder material data as a released engineering value.
Boundaries
- Verify actual grade and density before relying on a result. Bundled generic materials are editable placeholders.
- Assign a material to every included body before claiming complete mass, center of mass, or inertia.
- Keep configuration and assembly placement settled while measuring.
- Do not treat this workflow as structural, thermal, or manufacturing analysis.
Procedure
- Record the project, active configuration, included bodies or occurrences, units, required properties, and approved material grade and density source.
- Select each body and choose Inspect → Material. Assign the matching material or create an explicitly labeled verified density when the bundled generic value is not adequate.
- Confirm that every included body has density. Exclude a body only when the requested scope says to exclude it and the report names that exclusion.
- Wait for the configuration, features, and assembly placements to settle.
- Choose Mass & health. Record exact volume and surface area, mass, center of mass, inertia tensor, principal moments and axes, and radii of gyration as required by the task.
- Check the missing-material list. If it is non-empty, report the known subset and center of volume only; do not relabel them as complete mass properties.
- Perform a reasonableness check from volume × density and compare it with the reported mass. Save the material source, scope, configuration, and results.
--- name: assign-material-and-check-mass-in-partmode category: design description: Assign materials to PartMode bodies and verify revision-bound volume, mass, center of mass, inertia, and geometry health. Use when someone asks how much a part or assembly weighs, needs density-driven properties, or sees an incomplete mass result. --- # assign-material-and-check-mass-in-partmode Calculate mass properties without presenting placeholder material data as a released engineering value. ## Boundaries - Verify actual grade and density before relying on a result. Bundled generic materials are editable placeholders. - Assign a material to every included body before claiming complete mass, center of mass, or inertia. - Keep configuration and assembly placement settled while measuring. - Do not treat this workflow as structural, thermal, or manufacturing analysis. ## Procedure 1. Record the project, active configuration, included bodies or occurrences, units, required properties, and approved material grade and density source. 2. Select each body and choose **Inspect** → **Material**. Assign the matching material or create an explicitly labeled verified density when the bundled generic value is not adequate. 3. Confirm that every included body has density. Exclude a body only when the requested scope says to exclude it and the report names that exclusion. 4. Wait for the configuration, features, and assembly placements to settle. 5. Choose **Mass & health**. Record exact volume and surface area, mass, center of mass, inertia tensor, principal moments and axes, and radii of gyration as required by the task. 6. Check the missing-material list. If it is non-empty, report the known subset and center of volume only; do not relabel them as complete mass properties. 7. Perform a reasonableness check from volume × density and compare it with the reported mass. Save the material source, scope, configuration, and results. ## Done - Every included body has an identified material and density source - Mass & health reports a valid exact body set with no hidden missing material - An independent volume × density check is consistent with the reported mass - Configuration and assembly placement are named in the result - The report states that material properties are not certification or simulation
