Description

Examples of extrusion

Usage

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。

Parameters

• Dir: 挤型方向。如果Dir Mode为'Custom'，您就可以编辑Dir。 否则，Dir仅为只读，且根据连接形状（linked shape）开始计算。

• Dir Mode: 设置如何控制Dir参数。'Custom'选项意味着Dir是可编辑的。'Edge'表示Dir要通过Dir Link根据一条待连接的边（线）来确定。而'Normal'则表示Dir正交于输入形状的所在平面。

• Length Fwd: 挤型的距离。如果Length Fwd与Length Rev皆为0，则采用Dir向量的长度。

• Length Rev: 另一种与Dir方向相反的挤型长度。

• Solid: 如果此项为True，对一条闭合边或一条闭合连线进行挤型，将生成一个对应实体。如果此项为False，则生成一个对应的壳。

• Reversed: 将挤型对象调转至Dir的相反方向。

• Symmetric: 如果此项为True，则以输入形状为中心向指定方向及其相反方向进行挤型，且挤型总长度为Length Fwd。并忽略Length Rev。

• Taper Angle and Taper Angle Rev: 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. Taper Angle Rev sets the taper for the reversed part of the extrusion (the part from Length Rev).
  • introduced in version 0.20 Inner structures receive the opposite taper angle. This is done to facilitate the design of molds and molded parts.
  • version 0.19 and below Tapered extrusion is only supported for shapes without inner structures. Taper does not work well if the shape contains B-splines.

• Face Maker Class: sets C++ class name of face making code, which is used when making solids from wires. This property is here mainly for maintaining backward compatibility. Do not touch, unless you know what you are doing.

Task对话框

• 'Direction' 单选按钮：设置计算挤型方向的方式。

• Select button: click it, and then pick an edge in 3D view. That edge will appear in text field next to the button, in format "ObjectName:EdgeN". You can also type the link manually. Values X,Y,Z will be filled according to the edge direction.

• 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。

• Symmetric: 以对称的方式向指定方向及其反向进行挤型，因此输入形状将位于生成挤型对象的中部。

• Taper Outward Angle: positive angle means profile is expanded at other end of extrusion.

• 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. introduced in version 0.20

• The task dialog 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.

• Part Extrude always creates a standalone shape. PartDesign Pad fuses the extrusion result to the rest of the Body.
• Part Extrude doesn't care where it is in model tree. PartDesign Pad can only live 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.
