PTC Creo, formerly known as Pro/ENGINEER, is a 3D CAD/CAM/CAE feature-based, associative solid modeling software. It is one of a suite of 10 collaborative applications that provide solid modeling, assembly modelling, 2D orthographic views, finite element analysis, direct and parametric modelling, sub-divisional and NURBS surfacing, and NC and tooling functionality for mechanical designers. Creo Elements/Parametric compete directly with Solidworks, CATIA, and NX/Solid Edge. It was created by Parametric Technology Corporation (PTC) and was the first of its kind to market.〔http://www.ptc.com/company/history-and-acquisitions.htm〕 The application runs on Microsoft Windows. The UNIX version was discontinued after 4.0,〔(), retrieved 2011-12-06〕 except x86-64 UNIX on Solaris. The name change to Creo 1.0, also known as Pro/ENGINEER Wildfire 5.0,〔http://www.ptc.com/appserver/wcms/standards/textsub.jsp?&im_dbkey=118992&icg_dbkey=21〕 took place on October 28, 2010, which coincided with PTC’s announcement of Creo, a new design software application suite. Creo Elements/Pro will be discontinued after version 2 in favor of the Creo design suite. ==Overview== Creo Elements/Pro (formerly Pro/ENGINEER), PTC's parametric, integrated 3D CAD/CAM/CAE solution, is used by discrete manufacturers for mechanical engineering, design and manufacturing. Pro/ENGINEER was the industry's first rule-based constraint (sometimes called "parametric" or "variational") 3D CAD modeling system. The parametric modeling approach uses parameters, dimensions, features, and relationships to capture intended product behavior and create a recipe which enables design automation and the optimization of design and product development processes. This design approach is used by companies whose product strategy is family-based or platform-driven, where a prescriptive design strategy is fundamental to the success of the design process by embedding engineering constraints and relationships to quickly optimize the design, or where the resulting geometry may be complex or based upon equations. Creo Elements/Pro provides a complete set of design, analysis and manufacturing capabilities on one, integral, scalable platform. These required capabilities include Solid Modeling, Surfacing, Rendering, Data Interoperability, Routed Systems Design, Simulation, Tolerance Analysis, and NC and Tooling Design. Creo Elements/Pro can be used to create a complete 3D digital model of manufactured goods. The models consist of 2D and 3D solid model data which can also be used downstream in finite element analysis, rapid prototyping, tooling design, and CNC manufacturing. All data are associative and interchangeable between the CAD, CAE and CAM modules without conversion. A product and its entire bill of materials (BOM) can be modeled accurately with fully associative engineering drawings, and revision control information. The associativity functionality in Creo Elements/Pro enables users to make changes in the design at any time during the product development process and automatically update downstream deliverables. This capability enables concurrent engineering – design, analysis and manufacturing engineers working in parallel – and streamlines product development processes. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「PTC Creo Elements/Pro」の詳細全文を読む スポンサード リンク
