鏡射
相對一特定平面或平坦面來仿製一或多個所選零件或曲面。藉由加入或移除材料，或在路徑上使零件相交來建立新的零件或曲面，或是修改現有的零件或曲面。也可以在啟用的鈑金模型操作中使用鏡射。

Onshape 提供多個複製排列的功能，可讓您在 Part Studio 中建立零件、特徵或面的額外實例。可用的複製排列類型有線性、環狀、鏡射與曲線複製排列。
線性複製排列會沿單一方向產生實例或在兩個方向上建立實例的陣列。
環狀複製排列會繞一個軸產生實例。
鏡射複製排列會相對於一個鏡射平面反射實例。
曲線複製排列會沿一曲線或路徑產生實例。
選擇一個複製排列類型。
A part pattern creates additional instances of selected parts. When you choose a part pattern, Boolean options are available to create new, add, remove, or intersect.
The new tab creates new parts for each instance of the pattern. Use this operation carefully as multiple identical parts within a part studio show as separate and unique parts within an assembly and bill of materials, and this is not a recommended practice.
The add tab adds material to existing parts. For overlapping parts, an add operation can join multiple parts into one.
The remove tab removes material where the pattern instance intersects parts.
The intersect tab leaves material where the pattern instance intersects parts.
The Boolean options allow parts to be used as tooling bodies to add or remove material or preserve the intersection of the pattern instances and the existing geometry.
A feature pattern replicates one or more features selected from the features list.
By default, feature patterns do not account for the seed features end type. In cases where the end type varies, select reapply features to regenerate parts from the selected features, including feature dependencies and end conditions. Use this option only when necessary, as it can affect performance and regeneration times.
Face patterns replicate selected faces. They result in the best performance as the computational load is much lower for faces than for parametrically bound features or parts. Therefore, they are preferred over feature or part patterns when the resulting geometry is identical.
In cases where faces are tangentially connected or form a recognizable geometric feature, such as a pocket or protrusion, use create selection to select the subset of faces to be patterned more easily.
Set the type of face selection, select the face or faces and click add selection.
All patterns except mirror contain an option to skip instances. Skipping instances is helpful when encountering conflicting geometry or when you wish to exclude particular instances. Onshape displays a selection point outlined in gray for each instance. You can skip an instance by selecting its respective selection point or using a box selection to select multiple instances simultaneously. Onshape highlights the selection points of skipped instances in light blue.
The merge scope determines which parts are affected by the pattern feature. For example, indicate which parts should be cut by a patterned pocket by including them within the merge scope. Parts not included within the merge scope are unaffected by the pattern feature.
Select merge with all to include all parts in the merge scope.
Video example: Mirror
Video transcript: Mirror
The Mirror feature replicates parts, surfaces, faces, or features across a mirror plane.
Select the appropriate options for the Pattern type and seed instance. This example creates an opposite-hand version of a part. With focus on Mirror plane, select a planar face, standard plane, Plane feature, or Mate connector. For a Mate connector, the secondary axes serve as the mirror plane. Alternatively, click the Select mate connector button to define an implicit Mate connector as the mirror plane. Modify the selected Mate connector's alignment, position, or angle by clicking the mate connector icon in the Mirror plane field.
In this example, half of a symmetric part is modeled. Use the Mirror feature to mirror the geometry to the other side and join them together as one part. This technique can reduce modeling time for symmetric parts, and, in many cases, improves regeneration time in the Part Studio.

- Select the Result operation type:
- 零件 - 鏡射一個單一的零件或曲面
- Feature - Mirror a specific feature (or features) listed in the Feature list (an extrude, fillet, sweep, etc). Note that Feature does not work for sheet metal; see the Face pattern type for sheet metal modifications.
- Face - Mirror a specific face on a specific part or surface
- Select Result operation type:
- 新 - 建立造成新零件的新材料。
- Add - Create material added to the existing material.
- 移除 - 將材料從零件中移除。
- 相交 - 僅留下相交存在處的材料。
- 在選取了[要鏡射的圖元] 欄位的情況下，選擇要鏡射的圖元。
When selecting Faces to mirror, the Create Selection
can be useful to select related faces. - Click in the Mirror plane field to give it focus, then select the plane, planar face or Mate connector (implicit or explicit) about which to mirror. Click the
in order to select implicit Mate connectors. Once a Mate connector is selected, click the Mate connector icon in the dialog field (outline in blue below) to open a dialog with which to edit the Mate connector:

(Feature type only) If the Reapply features option is enabled, external references of the seed features will regenerate automatically on a per-instance basis.
If a sketch is selected, the seed sketch dimensions and constraints to the origin or default plane (Top, Front, or Right) are not reapplied. You can use this behavior to scope which dimensions or constraints are reapplied within a mirror:
- In a sketch, you can dimension and constrain entities to the origin or default planes to prevent these dimensions and constrains from being reapplied on each mirror instance.
- If you need to reapply dimensions and constrains to the origin or default plane, first create auxiliary sketches with lines and points constrained to the origin or default planes. Then, on the seed sketch, use these sketch entities as a proxy for the origin or default plane dimensions and constraints.
- Select whether to merge the new entity with other entities that touch or intersect its geometry:
- 如果幾何僅與一個零件接觸或相交，則自動會將該零件加入至合併的範圍中。
- 如果多個零件與幾何接觸或相交，則有模糊的情況產生，您必須選擇要合併的零件 (合併範圍)。
- 一個選擇多個接觸或相交零件的捷徑是核取全部合併來將接觸或相交的零件加入至合併範圍中。
請注意，如果布林運算是設定為「加入」、「移除」、或「相交」，且在合併範圍內沒有設定任何項目，則特徵會有錯誤。對於「新」的選項，因為不會對結果進行布林運算，所以不提供合併範圍。
