Open Shells (non-watertight)
An open shell (non-watertight) is a connected surface or set of faces that does not form a closed volume. Gaps or missing faces leave the solid open.
Open shells (non-watertight) cause CAM failures, meshing issues, vendor rejection, and rework. Many CAM and mesh generators require closed, watertight geometry.
Why it fails:
- CAM boundary detection breaks
- Mesh generation fails
- Vendors reject non-watertight solids
Knife Edges
A knife edge is an edge formed by two faces meeting at zero or near-zero thickness. The geometry has no measurable material width along that edge.
CAM and meshers choke on knife edges: unstable toolpaths, meshing artifacts, and non-manufacturable geometry. Detecting them in STEP and IGES before CAM or 3D printing avoids failed runs and rework.
Why it fails:
- Unstable toolpaths
- Meshing artifacts
- Non-manufacturable geometry
Wall Thickness
Coming soonDetect thin walls and risky thickness transitions that lead to sink marks, weak parts, and failed manufacturing.
What it catches:
- Variable draft thinning (tapered walls)
- Boss proximity thinning (inter-feature distance)
- False-positive near-miss tolerance cases
Sharp Edges
Coming soonFlag sharp edge conditions that violate safety thresholds or create finishing and handling risks.
What it catches:
- 90° exterior corner safety threshold
- Sharp junctions between curved surfaces
- Tolerance near-miss angles (false positives)
