Geometric DFM for Injection Molding: Pull Direction, Draft, and Undercuts
A technical look at how Odin computes mold-opening direction, evaluates per-face draft, detects undercuts, and turns injection molding DFM review into an auditable CAD pipeline.
Read moreHow Small Design Decisions Delay Time-to-Market
Minor geometry and DFM issues discovered late cause weeks of downstream delay. Learn how design decisions propagate through tooling, production, and launch — and what they cost.
Read moreDraft Angles in Injection Molding: Why Parts Stick in the Mold
Draft angles help injection molded parts eject cleanly, reduce surface damage, and lower tooling risk. Learn the practical draft guidelines engineers use before tooling.

Vendor Rejected My STEP File — What Went Wrong?
Vendors often reject “valid” CAD exports due to hidden geometry issues. Learn the most common causes and a quick checklist before you send files out.
Read moreWhy CAM Toolpaths Fail After Export — And How It Extends Your Timeline
CAM toolpaths fail because of export artifacts like open shells (non-watertight) and topology gaps. Learn how to catch geometry issues before manufacturing and prevent prototype delays.

Fusion, SolidWorks, Onshape: Why Geometry Errors Survive Export
Neutral file translation (STEP/IGES) can introduce subtle geometry faults across CAD tools. Learn why it happens and how to detect issues before manufacturing.
Read moreOnshape to STEP: Common Geometry Issues (And Why They Show Up in CAM)
The model looks clean—then CAM refuses toolpaths or the vendor flags geometry. The issue usually isn’t bad design; it’s geometry translation. Learn the most common problems and how to reduce STEP translation risk.

What Is an Open Shell (Non-Watertight) in CAD (and Why CAM Fails Because of It)
An open shell (non-watertight) is one of the most common geometry issues that breaks CAM, meshing, and vendor quoting. Learn what it is, how it happens, and how to detect it visually in STEP and IGES files.
Read moreKnife Edges in CAD: The Geometry Error That Breaks Toolpaths
Knife edges are thin, zero-thickness features that cause CAM, meshing, and manufacturing failures. Learn what they are, why they happen, and how to detect them visually.
