To improve workflow from CAD to cutter, ExactFlat v3 lets users organize pieces in complex projects, label edges, and annotate seams in various ways to simplify sewing instructions. Accuracy is promoted by initially accurate flat patterns and ability to flatten markings or sketches applied to surfaces in 3D on 2D pattern pieces. Promoting simplicity, users can obtain material and hardware costing with one button click and see real-time updates as changes are made.
