約束曲面

1. 按一下 。

   

2. 選擇要根據點或是網格資料來定義曲面。
   • 點 - 選擇定義曲面的頂點。系統會建立垂直於頂點的曲面。若要變更曲面的方位，在對話方塊中按一下頂點來顯示其他的選項：

     

     • 點按垂ˊ直欄位來加以選取，然後選擇要從模型建立曲面的方向。
     • 按一下結合連接器按鈕來選擇結合連接器。
     • 按一下反轉垂直按鈕來切換方位。
   • 網格 - 選擇網格本體或面來定義曲面。
3. 設定建立曲面時允許的公差。公差越大，所產生的曲面就越簡單與越大。
4. 按一下最佳化下拉清單，然後選擇要最佳化平滑度或是效能。
   • 平滑度 - 通常會產生有較低曲率的較高品ˋˊ質曲面，但是效能較慢且有更多的控制點。
   • 效能 - 較快的效能但產生較低品ˋ質的曲面。
5. 按一下偏差核取方塊來檢視原始點/網格與所建立曲面間的最大偏差。
   • 按一下顯示偏差核取方塊來在模型上顯示最大偏差或所有偏差。
   • 設定顯示偏差的限制。不會在模型上顯示任何低於所輸入限制的偏差。
6. 按一下 。

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. Create a new part or modify an existing one by adding, removing, or intersecting parts.
• 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.
• Constrained surface - Create a surface from a selection of points or mesh data within a specified tolerance. Display deviations and optimize for performance or smoothness.
