AutoCAD Mechanical is geared toward manufacturing processes. It allows engineers to create, modify, and document 2D mechanical designs faster than traditional drafting methods.
One of the most notable updates in AutoCAD Mechanical 2021 is the welding symbol update to support the latest ISO and DIN standard revisions (ISO 2553:2013 and DIN EN ISO 2553:2014). Changes include the revision of elementary and supplementary symbols, the addition of new weld notation (distance between two points), and multi-reference line support. With this enhancement, users can annotate documents using the latest welding standards while maintaining backward compatibility to open and edit legacy documents.
