What does Odin check for injection molding?

Draft-angle violations by surface, undercuts that block ejection, and thin-wall regions at risk of short shots or sink. Fillet detection and material-calibrated thresholds roll out next.

How does Odin determine the pull direction?

You pick the Class A (cosmetic) surface. Odin derives the pull direction; every check recomputes against it. Change the Class A and the analysis updates live.

Does Odin auto-fix the part?

Detection for drafts, undercuts, and thin walls is live with designer-readable recommendations. Fillet detection, auto-generation, and full geometry auto-fix roll out next.

What is an Class A surface and why does Odin care?

Class A is the cosmetic, user-visible surface of a molded part — it needs tighter draft angles and can't host the parting line. Odin uses your Class A pick to derive pull direction, avoid the parting line, and bias visible-face draft-angle thresholds. Texture-aware tightening rolls out next.

Does Odin do material-specific analysis?

Not yet. Odin uses sensible injection-molding defaults today; per-polymer thresholds, flow-length warnings, and sink-mark risk roll out next.

What does Odin export?

The updated CAD plus a human-readable report of every issue, severity, face, and fix applied.

WHAT ODIN CHECKS

Four checks. All computed against your pull direction.

Change the Class A — pull direction moves, every check recomputes. Actionable fixes, not textbook warnings.

Draft angles

Detection · live

Per-face draft-angle measurement against the pull direction, flagged against injection-molding minimums.

· Per-face angle measurement
· Parting line impact flagged
· Texture-aware minimums (e.g. MT-11020)coming

Auto-fix: coming

Undercuts

Detection · live

Features that block ejection. Redesign vs. side-action triage so you know what needs what.

· Ejection-blocker detection by pull vector
· Redesign vs. side-action triage
· Updates live when Class A changes

Auto-fix: coming

Fillets

Detection · coming

Sharp internal corners concentrate stress. Odin will flag them and auto-generate fillets sized to wall thickness.

· Sharp internal corner detection
· Radius sized from wall thickness
· Generated fillet exported with the file

Auto-fix: coming

Thin walls

Detection · live

Region-by-region thickness map. Sections at risk of short shots, sink, or warpage get flagged.

· Per-region thickness heatmap
· Flow length & sink risk flags
· Per-polymer thresholdscoming

INSIDE ODIN

Designer-readable issues. One fix per line.

Every issue names a face, a severity, and a fix you can apply. No raw FEA dumps.

·Severity tags so the worst issues surface first
·Per-face callouts you can click into the 3D view
·Recommended fix with a target value, not a textbook warning
