I know that Microvellum is currently working on being able to add annotations to the Composite Nests, which will be a welcome addition. However, it would be great if Microvellum added the ability to automatically add a Grain Direction Marker to the Composite Nest following the material database for length or width during optimization. The Grain Direction Marker should show up in the Nesting Optimization Report. This could be an optional checkbox in the optimizer, so you could have it or not.

This would provide a visual indicator for anyone reviewing the Composite Nest that they had the parts on the correct material, and it would provide a reference for the CNC operator to ensure the correct sheet by grain direction is used. Also, this would allow you to quickly process a work order and get it to the shop without having to manually add the grain direction marker to the grained sheets.
