For designing and manufacturing an assembly, it is important to know which parts go into the assembly, how many of each, how they are assembled, and how they should perform.
對於設計和製造裝配，重要的是要知道哪些部分進入裝配，他們應該有多少每個，它們是如何組裝，以及如何執行。
A Mate in Onshape fully describes how two parts will interact with each other by specifically controlling each degree of freedom through the use of things called Mate Connectors. You can think of a Mate Connector as a small, local coordinate system (an x, y, and z axis) for a joint between two parts. The Red line is the X-axis, the Green is the Y, and the Blue is the Z.
Onshape 中的配合通過使用稱為配合連接器的東西，通過專門控制每個自由度來充分描述兩個部件如何相互作用。您可以將配合連接器視為兩個部件之間的連接的小型局部坐標系（x，y 和 z 軸）。紅線是 X 軸，綠色是 Y 軸，藍色是 Z 軸。
Animations are a great way to view the motion of your Mate before accepting it. Onshape will automatically move the Mate in a way that will exercise the Degrees of Freedom. In a Revolute Mate the part will rotate, in a Slider Mate, the part will slide, in a Cylinder Mate, the part will slide and rotate, etc.
動畫是在接受配合之前查看配合動作的絕佳方式。Onshape 將自動配合，以行使自由度。在旋轉配合中，零件將會旋轉，在滑塊配合中，零件將會滑動，在圓柱配合中，零件將會滑動和旋轉等。
A relation is a way in Onshape to constrain degrees of freedom between two Mates. Where a Mate controls how many degrees of freedom a pair of parts has between them, a Relation can control how those degrees of freedom move with respect to each other. There are 4 types of Relations in Onshape: Gear, Rack and Pinion, Screw, and Linear. These relations rely on preexisting Mates to define the type of motion that will occur between two parts.
關係是在 Onshape 中限制兩個配偶之間自由度的一種方式。其中一個配合控制一對部件的多少個自由度可以控制那些自由度如何相對於彼此的移動。在 Onshape 中有 4 種類型的關係：齒輪，齒條和小齒輪，螺釘和線性。這些關係依賴於已有的配合來定義將兩個部件之間發生運動的類型。
