Executive summary
Common geometry robustness problems in CAD systems — and practical engineering solutions that hold in production. Audience: CAD kernel and geometry robustness engineers.
If you stay generic
- Self-intersections, slivers, and non-manifold edges
- Boolean instability on near-coincident faces
- Tessellation that hides B-Rep defects until CAM
If you commission custom work
- Detect and quarantine non-manifold and self-intersecting solids
- Use exact/filtered predicates for critical intersections
- Compare B-Rep validity before and after every major op
Why this topic shows up in discovery calls
Teams contact Hendoi when licensed kernels, brittle geometry, or slow visualization block product strategy. The metric that matters here is Robustness suite pass rate on industrial dirty-geometry corpora.
Technical buyer checklist
- Are acceptance tests written on your geometries before coding?
- Is IP portable if the vendor relationship changes?
- Do robustness and performance budgets gate releases?
- Can juniors reproduce a key case without tribal macros?
- Does the first release prove robustness suite pass rate on industrial dirty-geometry corpora?
Hendoi’s 3D CAD Kernel Development work is organized around modular architecture, demonstrable increments, and validation on your models.
