Options for calculating flat patterns
Another important thing to keep in mind when creating sheet metal defaults is how your 3D parts will be converted to 2D flat patterns for production. If you've been producing sheet metal parts, touch base with manufacturing to find out the methods they use to create their flat patterns. Let's take a look at how these flat patterns are generated by default. In the styles we have our sheet metal unfold methods. The current one that's active and the one that's usually the default for Inventor is a simple k factor. This is a calculation based on the thickness of the material that compensates for how much that material will stretch as it's bent into shape. If you're familiar with bend compensation. You probably already have formulas that you use to figure out how much that material will stretch based on different thicknesses and different angles. Another option, that manufacturing might use is a bend table. Autodesk Inventor comes with bend tables built in. And you can use that as a basis…
