The future of mechanical drafting
- [Narrator] While 2D drawings are still the primary means of communicating design data in industry, this may be about to change. In this video, we'll tell you about an exciting new technology called model-based definition that may one day reshape the way engineers and manufacturers communicate. Preparing 2D drawings for simple parts is fairly straightforward, but if you have a part with a lot of complex curvature, perhaps for ergonomic or aerodynamic reasons, defining this geometry on a drawing can be exceedingly difficult. In the late 1990s, as 3D modeling began to revolutionize product design, engineers wanted a way to use the 3D CAD files as the controlling document instead of a drawing. To address this need, the American Society of Mechanical Engineers developed a standard for model-based definition. The vision for model-based definition is that all the design data and requirements are embedded in a 3D CAD…
