You will acquire the knowledge necessary to complete the process of creating models from conceptual sketching, through to solid modeling, assembly design, and drawing production. You are taught how to find and use the modeling tools associated with familiar modeling strategies that are used in other 3D CAD software. This learning guide is designed for users that have 3D modeling design experience with other 3D CAD software packages (e.g., CATIA™, Inventor™, NX™, SolidWorks®, and so on).īy leveraging the experience users gain in working with other 3D modeling software packages, this hands-on, practice-intensive guide is developed so that users who are new to Creo Parametric can benefit from a shorter, introductory-level, learning guide. If you do any kind of aesthetic surface design, you want SubDs.The Creo Parametric 7.0: Introduction for Experienced 3D CAD Users learning guide is intended to provide accelerated introductory training in Creo Parametric 7.0 software.
It’s worth a watch, even if you’re not a Pro/E or Creo user, because it shows what can be done with SubD surfaces.
While it’s likely that PTC is trying to encourage their Pro/E users to upgrade to Creo, the video really highlights the difference in modeling methodology using SubD surfaces versus NURBS surfaces. PTC has recently posted a video that compares using Freestyle SubD surfaces in Creo Parametric 2.0 with NURBS surfaces in Pro/E Wildfire 5.0: It’s not only included at no extra charge with the base program, it’s well-integrated with Creo’s parametric modeling capabilities, allowing you to create aesthetic surfaces with SubDs, and precise surfaces (for interfaces) with NURBS. The Freestyle extension in PTC’s Creo Parametric 2.0 program is one of the most interesting SubD surface modelers. And the process of creating and editing SubD surfaces is quite a bit different too. SubD surfaces, though based on the same mathematical underpinnings as NURBS, are quite a bit different. Most, however, don’t use NURBS-they use subdivision (SubD) surfaces. There are a number of interesting tools available for doing organic shape modeling. While you could certainly find a way to model this shape with NURBS, and even get the nice G2 continuity shown here, it would definitely fall into the “pain in the neck” category: There is no standard definition for what an “organic shape” is. Probably the best definition, in the context of CAD, is that it’s a shape that’s a real pain in the neck to model using traditional methods with NURBS surfaces.
