When implementing ModelCHECK settings for multibody parts in Creo Parametric, especially for use cases like generative topology optimization, there are several strategies you can consider:
1. Check for Multiple Bodies: As you mentioned, a fundamental check is to determine if a part contains more than one body. This is crucial for multibody modeling and should be the primary check.
2. Check for Body Naming and Organization: Ensure each body in a multibody part is appropriately named and organized. This helps in maintaining clarity, especially in complex models where different bodies serve different functions or represent different materials.
3. Geometry Quality Checks: Implement checks for the quality of geometry within each body. This includes looking for small edges, sliver faces, or other geometry that might be problematic, particularly in generative topology optimization.
4. Interference Checks: In multibody parts, it’s crucial to check for interferences between bodies, which could indicate design issues or clashes that need to be resolved.
5. Volume and Mass Properties Checks: For multibody parts, checking the volume and mass properties of individual bodies can be important, especially if they are meant to represent different materials in generative design.
6. Feature Checks: Ensure that the features used to create each body are appropriate and optimized. This can include checks for redundant features, poorly defined sketches, or overly complex feature structures.
7. Parameter and Relation Checks: Verifying that the parameters and relations defining the bodies are correctly set up and that they adhere to your design intent. This is especially important in a generative design context, where the relationships between different parts of the model can be complex.
8. Check for Unused Bodies: In some design workflows, bodies are created and then not used in the final design. ModelCHECK can be used to identify and flag these for review.
9. Compliance with Standard Practices: Ensure that the multibody parts adhere to your organization’s standard modeling practices, such as layer assignments, color coding, or material properties.
10. Regeneration Checks: Ensure that the multibody parts regenerate without errors or excessive times, which can be an indicator of underlying issues in the model.
Remember, the specifics of these checks might vary depending on the exact nature of your design process and the capabilities of the version of Creo Parametric you are using. It’s always a good practice to tailor ModelCHECK settings to fit your organization’s specific needs and workflows.
