Parametric modeling is a computer aided design (CAD) software design tool that saves time—it eliminates the need for a design engineer to constantly redraw a design every time one of the design’s dimensions change.
This tool was developed by Rhino, a software program that evolved from AutoCAD.
This tool lets designers modify the entire shape of their design at once, not just individual dimensions one at a time.
但也有一些缺点与参数模型ing tools. Designers must often anticipate potential design changes and define features accordingly. Plus, the designer must define the relationships between features. For complex designs, capturing design intent can be a challenge.
So, developers created a tool known as direct modeling. This tool provides a geometric-based modeling strategy, rather than a feature-based format so that designers can quickly define and edit geometry.
Pro/ENGINEER (Creo 2.0 and higher) and SolidWorks (2012 and newer) offer direct modeling on top of existing feature-based parametric modeling. Direct modeling lets copy, move, split, replace, offset, push, and drag geometry in any way they need.
