Designing with 2D is Legit The Sensibility of Designing with 2D Geometry Using Drafting Tools to Design with 2D Geometry Using Feature-based Sketching to Design with 2D Geometry Using Direct Sketching to Design with 2D Geometry The Value of Swift and Smart 2D Design Summary and Conclusion
For years, the use of any 2D geometry was seen as a laggard practice. But in the past few years, engineering organizations have recognized the critical nuance between documenting and designing. In that light, designing with 2D geometry is a legitimate way to iterate and explore ideas in concept design and early detailed design. This eBook compares the use of Drafting, Feature-based Sketching and Direct Sketching capabilities for designing in 2D.
When it comes to the technologies that enable design work with 2D geometry, many of today’s CAD software applications provide both Drafting Tools and Feature-based Sketchers. Unfortunately, each of them poses unique problems when faced with the context of such early design efforts. Designers and engineers often use released engineering drawings or cross sections from finalized 3D models, each of which contain hundreds if not thousands of lines, curves, arcs and splines. Drafting Tools allow them to trim and extend those 2D geometric entities on a one-by-one basis. It does not, nevertheless, power intelligent change. On the other hand, Feature-based Sketchers enable smart modifications. But they inhibit the iteration and exploration of new ideas with their need to full define the location of every 2D geometric entity with constraints and dimensions. Fortuitously, an alternative for designing with 2D geometry has arrived. Direct Sketching, which applies Direct Modeling concepts to 2D geometry, enable intelligent change without inhibiting design iteration and exploration.
