sm drawings

Описание: This Fusion tutorial explains the best practices for creating technical drawings of sheet metal parts [00:00]. It emphasizes the need for two main views: the Formed View (the finished, bent part, used for dimensioning final geometry) and the Flat Pattern View (the unbent piece, used by manufacturing for cutting) [04:39, 06:39]. The video shows how to display the flat pattern, suppress the Bend Extents lines, and automatically insert a Bend Table that lists all bends for the manufacturing process [00:30, 00:39]. Critical dimensioning rules are highlighted: place all final dimensions (like hole positions) on the Formed View to check the final product, and use Ordinate Dimensions on the Flat Pattern to locate features and bend lines, while avoiding dimensioning across a bend line [05:57, 06:30]. The video also briefly covers using a Bill of Materials (BOM) to specify material thickness [08:18].
