Creo是一个整合Pro/ENGINEER、CoCreate和ProductView三大软件并重新分发的新型CAD设计软件包，针对不同的任务应用将采用更为简单化子应用的方式，所有子应用采用统一的文件格式。 Creo目的在于解决目前CAD系统难用及多CAD系统数据共用等问题。Creo在拉丁语中是创新的含义。Creo的推出，是为了解决困扰制造企业在应用CAD软件中的四大难题。CAD软件已经应用了几十年，三维软件也已经出现了二十多年，似乎技术与市场逐渐趋于成熟。但是，目前制造企业在CAD应用方面仍然面临着四大核心问题： 1）软件的易用性。目前CAD软件虽然已经技术上逐渐成熟，但是软件的操行还很复杂，宜人化程度有待提高。

2）互操作性。不同的设计软件造型方法各异，包括特征造型、直觉造型等，二维设计还在广泛的应用。但这些软件相对独立，操作方式完全不同，对于客户来说，鱼和熊掌不可兼得。

3）数据转换的问题。这个问题依然是困扰CAD软件应用的大问题。一些厂商试图通过图形文件的标准来锁定用户，因而导致用户有很高的数据转换成本。

4）装配模型如何满足复杂的客户配置需求。由于客户需求的差异，往往会造成由于复杂的配置，而大大延长的产品交付的时间。

Creo的推出，正是为了从根本上解决这些制造企业在CAD应用中面临的核心问题，从而真正将企业的创新能力发挥出来，帮助企业提升研发协作水平，让CAD应用真正提高效率，为企业创造价值。

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."
