Designing Innovatively with 铁CAD 2013

2013年5月21日

Design professionals are sometimes on an insatiable search for the perfect tool that will make us all the more effective at our work, expanding our creative horizons in improved form and reduced time. A CAD solution would be a system that provides the flexibility to handle several different design situations, yet enables fast and optimal changes easily. I think I may have found just such a system in 铁CAD.

作为CAD / CAM的资深人士,我关注了软件公司在设计领域的诞生,发展以及在某些情况下的死亡。优胜者是那些能够应用适用于各个行业的专业解决方案的CAD产品而广受欢迎的人。已经存在很长时间并且一开始就没有考虑现代原理的CAD软件可能不得不适应,但不一定总是成功。

My task in this review of 铁CAD then is to use my experience to survey what in my opinion are the concepts and differentiating points from other CAD systems, without going into the details of commands that are common to similar MCAD systems.

With the various CAD technologies available today having their benefits and limitations, it is an interesting surprise that 铁CAD manages to incorporate the best of many technologies into one design methodology that they called Innovative Design.

Looking at 铁CAD’s Configurations

To understand the product environment that I will be writing about, it makes sense to give an overview of all the modules found in the 铁CAD suite of software.

  • 铁CAD is the core product for creating 3D models and 2D drawings. It combines direct editing and history-based parametric environments, with both ACIS and Parasolid kernels. Much of the editing can be done with drag-and-drop 3D intelligent parts and features, manipulated by the TriBall positioning utility interface.
  • INOVATE可以单独使用,也可以与任何MCAD软件包配合使用,以从概念到3D的完整产品生命周期功能。
  • DRAFT是一个独立的2D机械制图程序。当它在2D模式下工作时,它还能够查看,参考,分析,组装和渲染3D模型,这些模型可以在2D环境中关联地详细描述。
  • COMPOSE不仅是查看带有测量,渲染和动画的3D模型的查看器,而且还可以用于配置具有智能定位和定向功能的公司产品的零件和组件。这是免费的。
  • TRANS is the translation add-on that offers additional formats like CATIA V4 and V5, Pro/E (a.k.a. Creo), NX, SolidWorks, and Inventor (IRONCAD, INOVATE, and 铁艺草稿 include standard solid formats such as ACIS, PARASOLID, STEP and IGES, and most graphical formats. 钢铁CAD组成 Translator options will include all the solid formats (basic graphical formats and 铁CAD’基本产品中包含的标准文件格式)。

The Many Environments of 铁CAD

After I installed and launched 铁CAD, I found it to have a very intuitive and user-friendly environment using menus, dialog boxes, and icons similar to those of other CAD programs. When there are too many windows on the same screen, then it might make sense to use a higher resolution monitor or add a second one.

有两种工作环境,即3D和2D:

3D环境涵盖了3D细节设计,3D可视化,逼真的渲染和动画等领域。我要强调的特征是,它总是尝试提供与当前正在进行的设计操作相对应的选项,因此,创意过程是流畅的–使我可以多考虑​​3D设计,而较少考虑功能。

2D环境专用于草绘详图布局。

在我开始新文档时,这两个环境已引入流程。对话框显示以下选项供您选择:场景,工程图或CAXA草图。让我按顺序向您描述。

铁CAD’s Scene Environment

Scene is dedicated to 3D design. Unlike other MCAD systems, 铁CAD makes it possible to create single or multiple parts and/or assemblies in the same scene. It uses either the ACIS or Parasolid modeling kernel, which ensures precise and error-free import/export of native and neutral CAD files and the system can leverage both kernels modeling capabilities to achieve desired design modifications where a single kernel alone may simply fail. I should also note that the scene environment provides a good variety of environmental effects for more realistic-looking models (see figure 1).

铁CAD’场景环境与某些高端MCAD建模器的组织结构相似,概念上是所有组件的容器– features, parts, assemblies, imported parts, renderings, and animations. I verified the flexibility of 铁CAD’的方法是,我可以决定在设计的任何阶段使用哪种场景结构;它’s possible to keep all the components in a single scene. Alternatively, I can break out individual components into individual scene files, which then allows me to reference the same component in multiple files. As is typical in other MCAD packages, 铁CAD allows changes to be edited as I need them. For instance, the assembly structure can be rearranged and reordered during the design process using the Scene Browser.

One other item I want to highlight about assemblies: when I perform cut operations on an assembly, 铁CAD also cut the parts of the assembly. This feature makes me very productive.

铁CAD’绘图环境

铁CAD has two drafting environment, named Drawing and CAXA Draft.

The Drawing environment is where I work when needing to produce 2D drawings. I found it good enough to create all versions of drawings, for it supports associative views of existing 3D parts and assemblies, along with any annotation required, such as dimensions and notes. 铁CAD also places BOMs, symbols, blocks, layers, and frames (see figure 2).

The other 2D detailing environment is the CAXA DRAFT environment (see figure 3). It consists of a 2D design system that is nearly as powerful as AutoCAD, the most recognized 2D CAD package in the industry, complete with a familiar interface. This environment allows me to use the full capabilities of a standalone 2D drafting application, edit legacy DWG/DXF files, and to employ tools to detail 3D data from 铁CAD.

我想稍微介绍一下CAXA DRAFT,因为我认为这是一个非常有用的系统,特别是对于拥有2D工程图并需要使用它们来生成3D模型的设计师而言。 (许多著名的MCAD系统缺少这样的内置功能。)设计数据布局是通过3D界面完成的,该界面允许使用标准视图,剖视图,局部视图和许多其他视图来详细描述3D设计。他们保持与3D场景数据的完全关联,此外,’可以创建物料清单(BOM)。

设计设计师想要的方式
Well, you may find the title of this section curious, but after spending some time with 铁CAD, I found it flexible in the way I conduct the design process. As designers, we spent years getting experienced in way a particular CAD system operates. Flexibility, then, is something we could consider as revolutionary –或至少非常有趣。

铁CAD achieves its flexibility by combining two design environments that are different. One 铁CAD calls “innovative design”(即,基于特征历史记录和直接编辑自动混合在单个零件的结构中),其他“structured design,”传统的基于历史记录的结构,它还支持按历史记录顺序直接编辑功能。这种结合使我们能够选择最适合我们在单个零件级别上设计的零件的工艺!

创新设计方面提供了灵活性,使我们无需考虑零件的历史或约束即可直接操纵零件,同时保留零件设计信息。这在设计概念模型时至关重要。

Another useful aspect to 铁CAD’s混合特征环境是当我们处理不包含特征信息的导入数据时,可以添加具有特征的零件(参见图4)。因此,无论基础定义如何,我们都可以直接编辑几何。

The other side is the conventional 3D modeling environment, which 铁CAD calls “Structured Design.”它允许我们使用嵌入式设计意图来构建刚性的,依赖于功能的零件。它可以更好地控制未来的变化。结构化设计环境包括我们从其他MCAD系统中了解到的所有传统的强大的多实体功能,例如可以使用布尔运算组合的2D草图,实体特征,3D曲线和曲面特征。最后,无论功能顺序如何,我们都可以将设计转换为创新部分,从而在修改设计时具有更大的灵活性。

智能制作形状

超越双重设计环境,当我了解到给定形状的智能时,我感到惊讶。“IntelliShapes.”可从目录浏览器访问这些形状。 IntelliShapes令我惊讶的是,它们的强大功能和灵活性,以及​​通过简单的拖放操作就非常易于使用。可以在“场景”模式下将它们放置在现有形状的表面上。

IntelliShape可以是正数或负数,表示它是实心或孔(请参见图5)。当我在形状/零件上放置正(实心)时,会向其中添加材料。如果是负片(孔),则材料被去除。一遍又一遍地经历了’我会再三感到惊讶,因为这很容易。放置到位后,我可以通过许多替代方法来更改它们的位置,包括非常漂亮的Triball,并通过Sizebox手柄进行许多修改。

IntelliShapes来自目录浏览器,该浏览器将它们分为几类。首先,类别是“形状”,“高级形状”和“工具”,但是我们可以添加更多内容,因为浏览器是完全可定制的。这使我们可以根据需要保存和组织组件。

IntelliShapes具有可编辑的参数,如图6中的齿轮所示。这意味着每个形状代表数十个或数百个变体。

一球两球TriBall

Beyond the punny title, I found the TriBall interface a great positioning tool due to its versatility, range of application, and ease of use. Although 铁CAD has other positioning tools, none is as comprehensive as the TriBall. Sure, similar all-in-one systems can be found in other CAD system, but only this one joins all of them in a single function.

It offers complete repositioning of items such as shapes, attachment points, parts and faces on parts, assemblies, profiles, 2D shapes, and 3D curves. That the TriBall is this mature is no surprise, given that 铁CAD invented the interface.

进一步的设计工具

铁CAD possesses the complete set of tools that provide all the functions we need for our design work. In addition to solid features, assemblies, Intellishapes, and 3D curves, I can add surfaces, sheet metal and visualization tools. Let me describe these briefly.

I can see that 铁CAD’s wide range of surfacing tools allows us to create surface shapes from existing edges or 3D curves (see figure 8). It includes surface types like mesh, loft, ruled, spin, and sweep (parallel, fixed, bounded, and two guide curves). Also, there are face-face fillet surfaces, extended surfaces, trimmed and untrimmed surfaces, offset surfaces, and merged surfaces. 铁CAD definitely makes available most of the options needed for creating surfaces, without forgetting its conceptual premises of flexibility and easy generation.

As I dug into 铁CAD, another design alternative I found was sheet metal design. It works in a manner similar to the other design processes in 铁CAD. To form an initial sheet metal part, I can drag and drop standard IntelliShapes into a scene. Alternatively, I can create a lofted sheet metal part from existing 2D profiles. Once the basic part is defined, I can continue on to customize and refine the design using visual and precision editing techniques. The sheet metal can be a stand-alone part or be designed in-place with an existing part. I found it has a good level of response, and offers complexity similar to the other products available on the market.

Regarding visualization, 铁CAD offers a smart set of options for setting the visual style, rendering, realistic and textured. SmartMotions generate animations.

结论

I had a pleasant experience in analyzing 铁CAD. I found it full of both technical and conceptual surprises. 铁CAD has good performance and its flexibility makes the designer’使工作更轻松,更快,更动态。 3D思维得到了很好的支持和实施。

How does 铁CAD 解决方案 achieve this? By using hybrid environments it combines the best of both innovative and the classic structured ones (parametric or direct editing), and also with the application of Intellishapes –具有巨大潜力和易用性的智能功能。这种独特的工具可以非常简单地对组件进行构造,并且可以快速定位零部件,而不必担心约束的复杂性,甚至可以利用自动定位,定向和调整尺寸的优势。

为什么我’ve反复强调该产品的灵活性?因为它允许在需要时和需要的地方对产品进行直接建模更改,而无需在不受影响的区域中修改特征的定义,从而使原始设计保持完整。这还包括与2D工程图的集成以及与3D数据的交互。

Finally I want to emphasize the great ability that 铁CAD has to reuse geometry imported from other native and neutral CAD formats. If these are files imported from Pro /E and NX, it is also possible to maintain the associativity with native data.

All this, combined with great visualization and ease of use, allow me to conclude that 铁CAD can cover all the needs of a 3D designer.
