2. 選擇環繞著所要封閉體積的圖元。圖元必須是相交的。

   選擇性地使用「保留工具」來於新零件建立處保留所選圖元。如果沒有選用「保留工具」，則將會刪除任何選取項目 (不是從草圖或平面而來) 的自身零件。

在第一個圖片中，選取了曲面與平面來做為邊界。在第二個圖片中，刪除了曲面 (並未使用保留工具)，由平面與曲面所限制的體積現在是一個實體零件。

保留工具

當選擇了保留工具時，會保留曲面，且體積是一個實體零件。

如果對於邊界的選取項目會產生多個實體，Onshape 會自動將實體合併為一個零件。

This lists the collection of surface feature tools. This is not an exhaustive list. Additional Feature tools may be used when modeling surfaces. See Surfacing for additional information.

• Thicken - Add depth to a surface. Create a new part or modify an existing one by giving thickness to a surface and converting it to a solid, adding or removing material from an existing part or surface, or intersecting parts in its path.
• Enclose - Create a part by selecting all boundaries surrounding an empty space to form a solid. Use any set of surfaces and solids (including planes and faces) that intersect each other or connect at a boundary to create a volume.
• Fillet - Round sharp interior and exterior edges and define as a standard constant radius, more stylized conic, or variable by selecting Edge fillet. Optionally apply a Full round fillet to create a seamless blend of one or more faces between two opposing sides.
• Face blend - Round sharp connected or disconnected interior and exterior faces to create a seamless blend between the faces or detach the blend to create new faces, defining a radius or constant width. Further define the blend cross section (rolling ball or swept profile), symmetry, control, trim, constraints, and limits.
• Delete face - Remove geometry from a part. Select whether to heal the surrounding faces (by extending until they intersect), cap the void, or leave the void open. This Direct Editing tool is especially convenient if you don't have the parametric history of the part, as is often the case with an imported part.
• Move face - Translate, rotate, or offset one or more selected faces. This Direct Editing tool is especially convenient if you don't have the parametric history of the part, as is often the case with an imported part.
• Replace face - Trim a face or extend a face to a new surface. This Direct Editing tool is especially convenient if you don't have the parametric history of the part, as is often the case with an imported part.
• 偏移曲面 - 偏移一個現有面、曲面或草圖區域來建立新的曲面。將偏移距離設定為 0 來就地產生一個副本。
• Boundary surface - Create or add a surface specified by its boundary profiles.
• Fill - Create a surface (or a part from surfaces) by defining boundaries and refine the surface with boundary conditions (instead of requiring the use of reference surfaces).
• 移動邊界 - 移動曲面的邊界線以延伸或修剪曲面。
• Ruled surface - Create a new or additional ruled surface from an existing edge or multiple edges of a sketch region.
• Mutual trim - Trim two adjacent surfaces by extending intersections to complete the trim.
