2. 請選擇邊線，也就是填補的邊界。

   

    

3. 選擇性地為每個所選邊線或曲線定義連續性 (您可以從小視角立方體功能表中選擇 [斑馬條紋] 來查看效果)：
1. 位置 - 使邊線在沒有互為相切或曲率關係的狀況下交會
   
2. 相切 - 在邊界與新曲面 (就像有參考曲面一樣) 間建立一個隱含的相切 (垂直於曲面的平面)。 僅能在選取的草圖中作用，無法用於其他的平坦曲線上。選擇性使用，選取時系統會啟用「相鄰面」欄位。選取任何一個面，其基礎幾何須與至少一個輪廓零件的曲線重合 (面與邊線不需相交或是同一零件的一部分)。
   
3. 曲率 - 與相鄰曲面的實際曲線相配。選擇性使用，選取時系統會啟用「相鄰面」欄位。選取任何一個面，其基礎幾何須與至少一個輪廓零件的曲線重合 (面與邊線不需相交或是同一零件的一部分)。

   例如，已為下方選擇的最左側邊線選取了連續性選項。注意到在視覺顯示條紋間的不同：

   Position:

   Tangency:

   Curvature:

4. Select Guides (points, vertices, points on a sketch, or curves) with which to influence the shape. The resulting surface intersects these points which will lie in the interior of the boundary. When curves are selected, the surface pushes through the curves and you can select from two types of calculations:
   1. Sampled - Uses the Sample Size to determine the number of vertices along the curves are used to calculate the surface. A long Sample size may result in the surface following the entire curve:

      3 的取樣大小：

      

      10 的取樣大小：

      

   取決於樣本的大小，曲面上可能會有波紋。

5. 精準 - 使用明確的曲線來形成曲面。請注意，此選項需要非常小心地設計與選擇曲線。詳細資訊請參考下方的範例。
6. 核取顯示 isocurves來評估其下曲面是如何被定義的。

   會以網格呈現未經修剪的下方曲面以顯示 iso 參數式曲線，讓您能夠評估其下曲面的品質。

導引頂點

選取 [導引頂點] 來進一步定義曲面的形狀：

使用精準選項的導引

特別是當導引曲線使用 [精準] 選項時，如果曲線互相交會，相交必須是在一個點上，就像是曲線與點是互為相切的。同時當使用 [精準] 選項時，曲線必須碰觸邊界但不可超過邊界。

導引並未相交

導引相切交會

導引與邊界相接觸

導引未與邊界相接觸

當選取 [取樣] 時，這種狀況是可行的：

但如果選擇了 [精準] 則不會成功。

導引在相切平面相交

缺乏相切導致失敗

導引符合相切準則

顯示 isocurves

已選取「顯示 isocurves」來顯示 iso 參數式曲線，讓您能夠評估其下曲面的品質：

• 當選取邊線時，可能會看到紅色的點；這些點代表的是邊界上遺失或開放的曲線。
• 如果操作會產生封閉的曲面 (建立體積)，Onshape 會自動建立一個實體零件 (如果已選取「加入」)。如果不希望建立零件，請使用「新」來保留所有曲面而不建立零件。

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.

2. 請選擇邊線，也就是填補的邊界。

   選擇性地為每個所選邊線或曲線定義連續性：

   1. Tangent - Create an implicit tangency (normal to the plane of the surface) between the boundaries and the new surface (as if you had a reference surface). Optionally, when selected, the Adjacent faces field is enabled. Pick any face in which underlying geometry is coincident with at least one profile part's curve (the face and edge do not need to intersect or be part of the same part).
      
   2. Curvature - Match the actual curve of the other surface. Optionally, when selected, the Adjacent faces field is enabled. Pick any face in which underlying geometry is coincident with at least one profile part's curve (the face and edge do not need to intersect or be part of the same part).
      
   3. Position - Make edges meet with no tangent or curvature relationship to each other
      
3. 選擇會影響形狀的導引 (點、頂點、在草圖上的點或曲線)。所產生的曲面會與這些點相交。當選取了曲線時，曲面會穿出曲線，然後您可以從兩種計算類型中選擇：
   1. 取樣 - 使用樣本大小來決定用來計算曲面的沿曲線頂點數量。較大的樣本大小可能會產生依循整個曲線的曲面，較小的樣本大小則會讓曲面可能有波紋。
   2. 精準 - 使用明確的曲線來形成曲面。請注意，此選項需要非常小心地設計與選擇曲線。
4. 核取「顯示 isocurves」來評估其下曲面是如何被定義的。
