"Luck plays no part in Diplomacy. Cunning and
cleverness, honesty and perfectly-timed betrayal are the tools needed to
outwit your fellow players. The most skillful negotiator will climb to
victory over the backs of both enemies and friends.
Who do you trust?"

The software generates a "Nest Result." Look at the Efficiency Percentage.
| Issue | Solution | | :--- | :--- | | "No valid flat pattern" error | Ensure your parts are Sheet Metal parts and have a Flat Pattern defined. If they are standard parts, you must derive a sketch from them to nest. | | Poor Efficiency | 1. Allow more rotation angles (45°, 90°). 2. Check if you are mixing parts of vastly different sizes. 3. Try a different sheet size. | | Parts overlapping | Check your Spacing settings. If the spacing is set to 0, parts may touch or overlap depending on kerf compensation. | | Grain Direction | If working with wood, ensure you have set the "Grain Direction" property in the part file, or restrict rotations in the Nesting Settings to 0 and 180 degrees only. | Autodesk Inventor Nesting 2025
Previous versions required users to re-define material thickness and kerf settings. In Inventor Nesting 2025, the tool now reads directly from the Inventor Sheet Metal Rules (i.e., K-factors, punch radii, and gap tolerances). If you change a material gauge in your original part file, the nesting process updates automatically without manual intervention. This eliminates a major source of "disconnected data" errors.
