Catia学习-卡扣 护套的参数定义(零件库)

1. 卡扣参数定义

 来到定义界面,选择卡口定义按钮

 选择卡扣

Edit Point编辑第一点,选择一个面,再选择对面的面,选择靠近的基面(可不选基面)

 

定义两点(不推荐)

取中间点(两点中间,点中点)

点面,选偏移平面,选择一个面,再选择中间点,面就到了中间面了

 

来到electical part页面

点击卡扣编辑按钮,选择外面第一个点,再选外面的面,选择中间面,第一点消失

再来到对面第三个点,选对面的面,中间面已经自动选择了

 

如果想定义可变尺寸扎带

知识工程工具栏调出来

1. 点击f(x) ,选 长度,单值,然后点新类型参数按钮

把新建的名字改成 ELEC-SUPPORT-RADIUS 

2. 草图右键 -半径对象-编辑公式,绑定上面这个参数(草图上是直径圆)

3. 然后再执行上面定义卡扣参数这个操作

注意: 不能定义最后一个基础面,否则无法可变尺寸

使用时

使用时一定要选择性粘贴 断开链接,否则会把之前的扎带跟着一起变大小

如果使用库: 

对扎带零件库,添加关键词“InstantiateAsNew”类型布尔型,值为真。如下


 

 

第四步,调用零件库,选中扎带右键,作为新部件实例化,如下图:

 

 

2. 连接器参数定义

选择定义连接器按钮

定义连接点

 

 

 

3 零件库的创建

1 新建目录编辑器

 

2. 添加章节和系列

默认名字和 章节1不要改了,在下面新建

 3. 系列中添加零件部件

 4 新建关键字

对扎带零件库,添加关键词“InstantiateAsNew”类型布尔型,值为真。如下


 

 

 

 

### CATIA CAD Software Overview CATIA (Computer-Aided Three-Dimensional Interactive Application) is a multi-platform software suite for computer-aided design (CAD), computer-aided manufacturing (CAM), and product lifecycle management (PLM). This comprehensive system supports multiple aspects of product development from conceptualization through production, including mechanical engineering, electrical systems, fluid systems, and more[^3]. The application provides an environment where users can create complex geometries with high precision. It integrates various modules that cater to different stages of the design process such as surface modeling, solid part creation, assembly design, drafting, simulation, analysis, etc.[^3]. In addition to its powerful geometry tools, CATIA also offers advanced features like knowledge-based automation which allows engineers to embed rules into their designs ensuring consistency across projects while reducing errors during repetitive tasks. Moreover, it facilitates collaboration among teams by enabling concurrent engineering practices wherein multiple designers or departments work simultaneously on interconnected parts without conflicts due to built-in data management capabilities within PLM solutions provided alongside CATIA installations[^4]. ### Usage Examples For instance, when creating a new project in CATIA V5: 1. Launching the program opens up the start page allowing selection between recent files or starting fresh. 2. Choosing 'New' leads one to pick specific templates based upon industry standards relevant to automotive, aerospace, shipbuilding industries amongst others. 3. Once inside the workspace, toolbar icons provide access to all necessary commands required for sketching profiles, extruding solids, applying fillets/chamfers, adding holes/taps, threading operations, assembling components together using constraints/joints, generating drawings complete with dimensions/annotations directly linked back to 3D models automatically updating whenever changes occur upstream; thus maintaining accuracy throughout documentation phases too! ```python # Example Python script interacting with CATIA via Automation API import win32com.client catia = win32com.client.Dispatch('CATIA.Application') documents = catia.Documents part_document = documents.Add('Part') # Create new Part document part = part_document.Part bodies = part.Bodies body = bodies.Item(1) sketches = body.Sketches origin_elements = part.OriginElements reference_plane = origin_elements.PlaneXY sketch_1 = sketches.Add(reference_plane) factory2d = sketch_1.OpenEdition() ```
