Description

描述

零件挤型工具根据用户指定的距离以特定方向将一个形状挤压成型。根据输入的形状类型与可选项的具体选择，输出的形状类型会有所不同。

下列内容为：在大多常见的情景中，根据指定的输入形状类型可能输出的形状类型，

  • 对一个顶点（点）进行挤型操作，将生成一个线性的边（线）
  • 对一个开放的边（例如，线、弧）进行挤型操作，将生成一个开放的面（如，平面）
  • 对一个闭合的边（例如，圆）进行挤型操作，将生成一个闭合面（如，一个开放端面的圆柱体），或者，如果如果参数"solid"为"true"将生成一个实体（如，一个闭合的实心圆柱体）
  • 对一个开放的连线（例如，一条底图连线）进行挤型操作，将生成一个开放的壳（若干互连的面）
  • 对一个闭合的连线（例如，一条底图连线）进行挤型操作，将根据可选项生成一个壳（若干连接的面），如果参数"solid"为"true"将生成一个实体
  • 对一个面（例如，平面）进行挤型操作，将生成一个实体（例如，长方体）
  • 对一个Draft Shape String进行挤型操作，将生成一个复合实体（生成的字符串是由多个字母实体复合而成）
  • 对壳中的多个面进行挤型操作，将生成一个复合实体。

Examples of extrusion

Usage

如何使用

  1. 在3D视图或模型树中选中待挤型的（多个）形状
  2. 点击工具栏中的 Extrude 图标，或前往Part → Extrude菜单
  3. 设置挤型的方向与长度，以及其他可选参数（参见后面的参数部分获得更多详情）。
  4. 单击OK。

操作完成后，模型树将列出与被选形状一样多的挤型对象。而每一个输入形状都将被置于其挤型对象之下。

Task对话框

  • OK: 创建挤型对象，并关闭对话框。
  • Close: 关闭对话框，神马也不做。
  • Apply: 创建挤型对象，却并不关闭此对话框。您可以继续在下侧的列表中选择另一个形状，以此创建更多的挤型对象。点击Apply可以多次创建多个挤型对象。
  • 'Direction' 单选按钮：设置计算挤型方向的方式。
  • Reversed checkbox: reverses the extrusion direction.
  • Select button: click it, and then pick an edge in the 3D View. That edge will appear in text field next to the button, in the format "ObjectName:EdgeN". You can also type the link manually or erase it. The values X, Y, Z will be filled according to the edge direction.
  • X, Y, Z 按钮：点击X按钮来设置+X轴上的挤型方向。再次点击则设置-X轴上的挤型方向。
  • X, Y, Z input fields: set or display the direction vector of extrusion. If both lengths are zero, the length of this vector sets the length of extrusion, and values are always in mm, regardless of unit preferences.
  • Length fields: 设置挤型的长度。此输入框支持用户输入的单位。
  • Taper angle along: draft angle for the along direction. Positive angle means profile is expanded at other end of extrusion.
  • Taper angle against: idem for the against direction.
  • Create Solid checkbox: 如果选中此项，对一条闭合的连线或边进行挤型将生成一个对应实体。如果在调用挤型工具之前便提前选中了一条闭合连线，则此项是默认选中的。
  • Shape list: 在此选择待挤型的形状。如果选中了多个形状，则将创建多个挤型对象。

Notes

  • App Link objects linked to the appropriate object types and App Part containers with the appropriate visible objects inside can also be used as profiles and to specify the direction.
  • The task panel does not offer a preview, yet. Apply will create an extrusion object every time you click it, which can be useful as preview; however, they will remain and yet another one will be created as you click OK. Undo can be useful to clean them up before clicking OK.

与PartDesign Pad的比较

PartDesign Pad也是一种挤型功能，但是与本页描述的挤型工具大有不同。

  • Part Extrude always creates a standalone shape. PartDesign Pad fuses the extrusion result to the rest of the Body.
  • Part Extrude can be placed anywhere in the model tree. PartDesign Pad can only be placed inside a PartDesign Body.
  • Part Extrude can extrude any object that has a Part geometry (OpenCASCADE shape), except for solids and CompSolids.
  • Part Extrude can extrude individual faces of other objects. PartDesign Pad will only accept either Sketch or faces of PartDesign objects as a profile.

Properties

See also: Property View.

A Part Extude object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:

Data

Extrude

  • 数据Base (Link): The shape to extrude.
  • 数据Dir (Vector): The extrusion direction. If 数据Dir Mode is Custom you can edit this property, otherwise it is read-only.
  • 数据Dir Mode (Enumeration): Sets how 数据Dir is controlled. Custom means 数据Dir is editable. Edge means 数据Dir is obtained from an edge (line) linked by 数据Dir Link. Normal means 数据Dir is perpendicular to the plane of the input shape.
  • 数据Dir Link (LinkSub): Parametric link to an edge (line) that sets the extrusion direction.
  • 数据Length Fwd (Distance): Length of extrusion along direction. If both 数据Length Fwd and 数据Length Rev are zero, the length of the 数据Dir vector is used.
  • 数据Length Rev (Distance): Length of additional extrusion, against direction.
  • 数据Solid (Bool): If true, extruding a closed edge or a closed wire will yield a solid. If False, a shell will result.
  • 数据Reversed (Bool): Reverses the extrusion direction.
  • 数据Symmetric (Bool): If true, extrusion is centered at the input shape, and the total length is 数据Length Fwd. 数据Length Rev is ignored.
  • 数据Taper Angle (Angle): Applies an angle to the extrusion, so that sides of the extrusion are drafted by the specified angle. Positive angle means the cross-section expands. Inner structures receive the opposite taper angle. This is done to facilitate the design of molds and molded parts.
  • 数据Taper Angle Rev (Angle): Sets the taper for the reversed part of the extrusion (the part from 数据Length Rev).
  • 数据 (Hidden)Face Maker Class (String): Superseded by 数据Face Make Mode (read-only).
  • 数据Face Make Mode (Enumeration): If 数据Solid is true, the facemaker class to use when converting wires to faces, otherwise ignored. The options are Simple, Cheese, Extrusion and Bullseye (default).
