直紋曲面

1. Click .

   

2. 選擇做為直紋曲面路徑的邊線，可以是單一條邊線或多條邊線。
3. Specify the Ruled surface type.
   1. Normal - The surface is normal to the edge.
   2. Tangent - The surface is tangent to the edge.
   3. Aligned with direction - The surface is aligned to an alternate direction; for example, a ruled surface aligned to construction geometry or the edge of another object.
   4. Angled from direction - The surface is angled from a selected direction; for example, a ruled surface angled to the direction of construction geometry or another object.



從左到右：垂直、相切、與方向對齊及與方向形成角度。

如果您選擇的方向無法從其中建立零件或整個直紋曲面，會在草圖中以紅色顯示方向，表示方向是錯誤的。請為您的對齊選擇一個新的方向邊線。

4. Specify the Angle for the surface, in relation to the selected edge(s), in degrees. Click the rotation icon to reverse the angle.
5. Specify the Distance from the edge(s). Click on the arrow icon to reverse the direction.

如果您選擇的角度或距離會迫使直紋曲面互為相交，則會出現錯誤，且不會顯示曲面。會在「直紋曲面」對話方塊的頂部與特徵清單中以紅色顯示直紋曲面。

6. (Optional) Select a Reference face. This is the face used as a reference for the Ruled surface. When an edge is first selected for the Ruled surface path, one of its adjacent faces is used as the edge's reference face and is automatically added to the dialog. To select a different or additional reference face (for example, the edge's opposing face), you can select the Reference faces area of the dialog and then select the new Reference face. To delete the previously selected Reference face, click the x icon to the right of the face label.
7. (Optional) select Vertex overrides. By default, the overall ruled surface definition is governed by the path created by the selected edge(s). However, you can override this behaviour and specify the ruled surface definition at any selected point, or multiple points. Select the Vertex overrides area of the dialog, and then select a vertex along the ruled surface path. You can then specify the following, for each Vertex override:
   1. Ruled surface type - Normal, Tangent, Aligned with direction, or Up to vertex. These are similar to the Ruled surface type above, but with the additional Up to vertex option - Up to a selected point (vertex) or Mate connector (implicit or explicit). Click the in order to select implicit Mate connectors. Once a Mate connector is selected, click the Mate connector icon in the dialog field to open a dialog with which to edit the Mate connector.
   2. Angle - Corner angle, in degrees. Click the rotation icon to reverse the angle.
   3. Distance - Corner distance. Click on the arrow icon to reverse the direction.



已套用「頂點覆寫」，其中頂點是用來操控直紋取面的角度與方向的。

可以使用覆寫標籤左側的下拉箭頭來展開與摺疊每個「頂點覆寫」。



8. (Optional) Use cubic interpolation - By default, the Ruled surface path uses linear interpolation. For finer continuity between the segments, you can select the cubic interpolation option.

   

   兩個鏡射直紋曲面段之間的線性 (左圖) 與三次 (右圖) 插補的範例。

9. (Optional) Show ruled lines - Displays ruled lines on all Ruled surfaces. The ruled lines are set per continuous path. The count can be set from 1 to 100, with 40 as a default.
10. Select the Corner type. Options are:
    1. Spun corner (default) - Uses curved spun corners to connect adjacent surface edges, if possible.
    2. Extended corner - Uses extended surface lines to connect adjacent surface edges, if possible.
    3. Loft corner - Uses loft corners to connect adjacent surface edges, if possible.
    4. No corner - Omits corners between adjacent surfaces edges.



從左到右：轉角、延伸角、提高角與無角落。

如果無法在曲面邊線間建立角落，系統會產生一個錯誤，並顯示這個訊息：

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.
