Creo是著名的三维建模软件Pro-E(Pro/Engineer)的接班产品,是美国PTC公司推出的CAD设计软件包。

Creo是整合了PTC公司的三个软件Pro/Engineer的参数化技术、CoCreate的直接建模技术和ProductView的三维可视化技术的新型CAD设计软件包，是PTC公司闪电计划所推出的第一个产品。

主要功能特色　　作为PTC闪电计划中的一员，Creo具备互操作性、开放、易用三大特点。在产品生命周期中，不同的用户对产品开发有着不同的需求。不同于目前的解决方案，CREO旨在消除CAD行业中几十年迟迟未能解决的问题：CREO解决机械 CAD 领域中未解决的重大问题，包括基本的易用性、互操作性和装配管理；CREO采用全新的方法实现解决方案（建立在 PTC 的特有技术和资源上）；CREO提供一组可伸缩、可互操作、开放且易于使用的机械设计应用程序；CREO 为设计过程中的每一名参与者适时提供合适的解决方案。

Built on PTC's heritage of innovation, Creo rethinks the very nature of product design, increasing collaboration and protecting data fidelity across any user role, any design mode, or any data source. The release of Creo 2.0 demonstrates PTC's unwavering commitment to solve the chronic challenges customers face with traditional CAD tools.

"PTC recently released version 2.0 of the Creo product design system, and the company seems to have moved the bar up yet again by making this release a tough act to follow. Version 2.0 sees more than 490 enhancements across the Creo app family -- much more than I can hope to mention here. Suffice it to say, whether your gig is parametric or direct modeling, moving from 2D to 3D design, or all the above, Creo 2.0 has some goodies for you. Here's a few that turned my head.

An interesting new role-specific app introduced in Creo 2.0 is called the Options Modeler. It's the tenth app in the Creo suite. What struck me about the Options Modeler is how it can help create and validate modular product designs early in the cycle. These modular designs can be large or small, complex or simple 3D assemblies. Doesn't matter. What does matter to you is that you can create re-usable product modules and define how they interface and assemble. Later, you can take the model and quickly re-use it to create and validate a new customer-specific product. When you combine Options Modeler with PTC’s Windchill product lifecycle management system, you can even generate and validate 3D representations of product configurations defined by a bill of materials.

With Creo Parametric 2.0, there are new capabilities for freeform surfaces, 3D cross sections, measurements, and change tracking. All of these are covered in today's Pick of the Week write-up, so I'm going to skip right to the new measure tool. Changes here sound like they can help you gain detailed knowledge into key dimensions and measurements of a selected surface. Basically, what it does is give you control over how and where measured results display on-screen. Then, this I like, it allows for simple re-use of the displayed values into other applications, even a Word doc.

Also very interesting is the new track changes capability in Creo Parametric 2.0. This lets you view, accept, or reject model changes made by others using Creo Direct. That is a cool addition that will speed up processes. It means that you can spread a design around the company -- say, to manufacturing -- and they can move on with their work and make model changes to their heart's content using Creo Direct. Or sales engineers can modify a design in Creo Direct on the fly with a client. None of that, however, makes a change to your design intent. You retain full control over what changes are reflected in the parametric model because you can yea or nay them.

Out of room and I just barely scratched the surface. You can read more about Creo 2.0 in today's Pick of the Week write-up. There's lots of links to get you started learning more. Also, you'll find some details on PTC's new version of Windchill that was announced at the same time as Creo 2.0. It has new integration with the company’s Integrity software system lifecycle management technology, which creates some pretty neat sounding requirements management capabilities. Windchill 10.1 also has a new mobile app for access to current product and process information from anywhere."
