Abstract

Modeling complex geometry today isn't just about creating engineering drawings, NC toolpaths and tooling are now created directly from 3D models. So you can't just make it look right on a drawing anymore. In this eBook, new technological advancements for CAD applications are discussed as well as their impact on engineering organizations.

Excerpt

As mature as CAD industry is, you would think that issues related to geometric complexity would have been addressed by now. But lo and behold, it still persists as a real issue. New advancements, however, offer some new mechanisms to work with geometer complexity. And that's what I've written about in this eBook. Here's a quick excerpt. Complex geometry is rarely built directly. Instead, it is created through progressively more complicated sets of geometry that build on top of one another. The mathematical algorithms used by CAD applications to calculate the spatial representations of complex geometry are exceedingly complicated. Sometimes CAD applications simply can't perform the calculations. Complex geometry can constrain efforts to make design changes. Even the most minor of modifications can cause a model to fail, forcing the user to fix or even rebuild it. Such efforts are painstaking and time consuming.
