Mass properties

Analyzing physical properties helps you evaluate how your designed model correlates to its physical counterpart. To verify design intent, you can calculate physical properties for parts.

Mass properties are not automatically updated with model changes. If model changes affect physical properties, the last known values become out of date and display N/A.

Tip: To maintain physical properties up to date when the model is saved, select the Update Physical Properties on Save option in the Application Options dialog box.

Why calculate physical properties?

It is useful to assign physical properties to components to locate a center of gravity, and to export data to another application for further analysis.

Which properties are calculated?

You can specify different materials for individual components, set analysis tolerances, and calculate values such as:

Can I override calculated physical properties?

User-defined override values are allowed for both mass and volume. By entering your own values, you can adjust for and accurately represent the true physical mass and volume of selected components that cannot be modeled.
