Inferring 3D curves from Perspective Drawings with this Interactive Design Tool.
Although I love 3D Modeling, it all starts with a 2D sketch, whether it be with a pen and pad or using a digital sketching tool. The 3D Sketching tools in CAD are not as intuitive as 2D sketching and are not user friendly, requiring you to design on XYZ axis planes, constraining lines and points (when using Parametric modellers). It requireds an advanced user, time and patience to learn effective 3D sketching. When all you want to do is conceptualise your ideas, your creativity can get lost by having to concentrate on using the software rather than developing an idea.
Most designers use the traditional drawing style known as Analytic Drawing. This involves sketching a perspective view on a flat surface, but when the sketch is done and you need to transfer the drawing into a CAD package, it needs to be redrawn. What if the 2D perspective sketch was designed in 3D in the background and one could concentrate on the design rather than being held back by the rules of the software? Wouldn’t that be awesome?
The Autodesk Research Analytic Drawing Project focuses on achieving that. It focuses on 2D sketches that infer 3D curves and constraints. It still relies on tangency and constraints but not in the same way as 3D CAD modelers, so it frees up the boundaries, this is similar to how Sketchbook Designer works for 2D Sketching. It focuses on the concept stage where your imagination should be the only limitation, not geometrical dimensions and constraints.
The examples shown by Autodesk don't demonstrate workflow from sketch to CAD, however, I expect that will be the goal, and it would be great to see that goal achieved.
