PythonOCC基础使用：基础装配——工业机器人装配

Love The Way You Lie 2022-01-27 06:59 468阅读 0赞

此章节是一脉相承于基础建模指令，由于这一章节没有opencascade官方铺路，为完全原创。注意该装配是指具有相应装配关系及约束存在的，并非只是实体相对位置的存在。

下面将以装配工业机器人手作为案例进行讲解，将分为以下几个部分：

*  1
 *  2
 *  3
 *  4

将会使用到以下函数：

AIS_InteractiveObject
    instance=AIS_ConnectedInteractive()
    instance.Connect()
    assembly=AIS_MultipleConnectedInteractive()
    assembly.Connect()

`AIS_ConnectedInteractive` 类，断开上一个视图的连接，并将高亮显示模式设置为0。这将突出显示线框演示文稿atypeofpresentation3d.top\_AllView禁用隐藏线删除。（Disconnects the previous view and sets highlight mode to 0. This highlights the wireframe presentation aTypeOfPresentation3d. Top\_AllView deactivates hidden line removal.）  
有如下函数

*  `AcceptShapeDecomposition()`
    
    Informs the graphic context that the interactive Object may be decomposed into sub-shapes for dynamic selection.
    
    Return type: bool
 *  `Connect()`
    
    1.Establishes the connection between the Connected Interactive Object, anotherIobj, and its reference.
    
    Parameters: anotherIObj (Handle\_AIS\_InteractiveObject &) –  
    Return type: void

1.  Establishes the connection between the Connected Interactive Object, anotherIobj, and its reference. Locates instance in aLocation.  
    Parameters:
    
    anotherIobj (Handle\_AIS\_InteractiveObject &) –  
    aLocation (gp\_Trsf) –

Return type：void

*  `ConnectedTo()`
    
    Returns the connection with the reference Interactive Object.
    
    Return type: Handle\_AIS\_InteractiveObject
 *  `Disconnect()`
    
    Clears the connection with a source reference. The presentation will no longer be displayed. Warning Must be done before deleting the presentation.
    
    Return type: None
 *  `HasConnection()`
    
    Returns true if there is a connection established between the presentation and its source reference.
    
    Return type: bool
