It is only in the last few years that direct modeling has really started to come to the fore. While it has previously only been used in a few functions, many engineers and designers are now turning to a direct modeling approach in some of their work. In this blog post, we’ll out line why this is the case.
HOW IS DIRECT MODELING DIFFERENT TO PARAMETRIC MODELING?
There is a fundamental difference between direct and parametric modeling. While parametric modeling relies on the end geometry of a feature being integrated with all the stages that go into making that feature, this is not the case for direct modeling.
