3D Modeling - Assemblies

3D建模 - 裝配

學習要點

1. 關於自由度的課程(degrees of freedom)
2. 部件配合介紹(assembly Mates)
3. 配對連接器(Mate Connectors)
4. 使用三重軸操縱零件位置(Manipulating part position with the triad)
5. 解釋配合和關係(Mates and Relations)
6. 動畫配合(Animating Mates)
7. 鏈接文檔簡介
8. 配合應用限制

Mates

Mates in Onshape are different than mates in traditional CAD systems. There is only one Onshape Mate between any two instances, and the movement (degrees of freedom) between those two instances is embedded in the Mate.

Assembly

1. Assembly tab is where you define a hierarchical structure of part and subassembly instances of an Assembly.
   使用“裝配”可以定義裝配的零件和裝配實例的層次結構。
2. It is also where you define degrees of freedom and relations.
   它也是您定義自由度和關係的地方。
3. You are able to have more than one Assembly tab in a document.
   您可以在文檔中擁有多個“裝配”。
4. One Assembly can instance another Assembly as a subassembly, and/or instance a part directly. 
   一個組件可以將另一個組件實例化為子組件，或直接實例化一個部件。
