FAQPage Schema

How do I verify B-Rep geometry watertightness and manifoldness in CAD solid modeling?▼

To verify B-Rep geometry watertightness and manifoldness in CAD solid modeling, run the solid-verification skill on your model to check for free edges, validate topological correctness, and ensure proper tessellation closure.

What is B-Rep topology validation and when do I need it for solid modeling?▼

B-Rep topology validation is the process of checking geometric correctness, face counts, and surface types in solid modeling. You need it after a geometry change to ensure the solid remains watertight, manifold, and correctly classified.

How do I check material classification and volume accuracy after a CAD geometry change?▼

To check material classification and volume accuracy after a CAD geometry change, run the solid-verification skill to validate B-Rep closure, verify tessellation watertightness, and confirm that the resulting geometric properties are correct.

Do I need brepkit operations and validation libraries to validate solid geometry?▼

Yes, you need the brepkit operations and validation libraries to validate solid geometry. The solid-verification skill requires these dependencies to perform B-Rep topology validation, check for free edges, and verify mesh watertightness.

Why does my B-Rep model have free edges and how can I check its closure?▼

B-Rep models have free edges when topological boundaries are not properly connected. You can check B-Rep closure by running the solid-verification skill to detect free edges, verify manifoldness, and ensure tessellation closure is watertight.

Can I validate surface types and face counts in a brepkit solid model?▼

Yes, you can validate surface types and face counts in a brepkit solid model by running the solid-verification skill, which performs a census check to ensure the correct face count and surface types match the expected geometry.
