橋接曲線
建立連接任兩個點、頂點或結合連接器的一條曲線。所產生的曲線會列於「特徵」清單與「零件」清單中。


在圖形區域中至少有兩個草圖點或頂點的情況下:
- Click the Bridging curve feature (
) on the toolbar.
- Select one of the following to act as the Start:
- 一個點或頂點,然後選擇性地選取一個面。
- An existing Mate connector. If one does not exist, click the Mate connector icon
to create a new implicit Mate connector.
- Select one of the following to act as the End:
- 一個點或頂點,然後選擇性地選取一個面。
- An existing Mate connector. If one does not exist, click the Mate connector icon
to create a new implicit Mate connector.
- For each point, vertex, or Mate connector (Start and End), select a continuity definition:
- Match tangent - The curve ends at the point, vertex, or Mate connector and is tangent to the edge, face, or Mate connector's Z-axis.
- Match position - The curve ends at the vertex or Mate connector origin point.
- Match curvature - The curve matches the curvature of the guide curve, face, or Mate connector's Z-axis in addition to the tangency.
- Match flow (G3) - The curve matches the flow (G3) continuity of the guide curve, face, or Mate connector's Z-axis.
Onshape 會記住對連續性定義的選擇,在後續的操作中打開對話方塊時即會是之前所做的選擇。
- For all continuity (match) options except Match flow (G3), select a method to adjust the bridging curve:
- Control points - Check Edit control points, and adjust the points numerically via the dialog, or directly using the arrows in the graphics area.
- With Match tangent selected, adjust the start and/or end magnitude of the control points
- With Match curvature selected, adjust the start and/or end magnitude of the control points, in addition to the end curvature offset
- Magnitude/bias - When Match tangent is selected for at least one vertex or point, you have the option to specify a Magnitude, any positive number (defaults to 1), to further define the shape of the curve. Magnitude is a scaling factor applied to Onshape's default calculation. The closer you get to zero the straighter the line. The larger the Magnitude the faster the curve 'shoots out of' the selected point or vertex.
When Match tangent is selected for two or more vertices or points, you have the option to specify a Bias value between 1.000e-4 and 0.999. This weights the tangency toward one side of the curve or the other. A value of 0.5 weights the tangency equally. This determines whether the curve 'shoots out more' from one side (closer to 0) or the other side (closer to 1).
- Control points - Check Edit control points, and adjust the points numerically via the dialog, or directly using the arrows in the graphics area.
- Edit control points - (Available only with Control points.) Check this option to control the Start/End magnitude, Start/End curvature offset, and Start/End flow offset (Match flow (G3) continuity only):
Control points and their corresponding manipulators in the graphics area
Before checking Edit control points
After checking Edit control points, adjust each setting numerically in the dialog or by dragging the manipulator arrows on the model
- Edit edge positions - Check this option to control where to locate the Start edge position and End edge position:
Edge positions and their corresponding manipulators in the graphics area.
Edit edge position selected
Start edge position and End edge position modified
- Click the checkmark (
) to accept the bridging curve.

In addition to entering a numeric value for Magnitude you can drag the arrow to adjust the Magnitude of the curve as shown below on the left corner of the new curve:
In addition to entering a numeric value for Bias you can drag the circle to adjust the Bias of the curve as shown below, affecting the left side of the curve:

您無法顯示/隱藏與曲線相關聯的特徵;請改用零件清單中顯示/隱藏的功能。
- 如果您選擇了配對位置,則不需要選擇邊線。
- 如果您為清單上的項目選擇了一個頂點,且僅有一條邊線是來從頂點而來,則您不需要選擇邊線。
- 如果您選擇了頂點且有多條從頂點而來的邊線,則您需要選擇一條邊線。
- 如果您選擇了一個頂點與一條邊線,則頂點必須是在邊線的一個端點上 (不需是邊線的頂點,只要在同樣的位置)。
- 您也可以選擇一條邊線而不選擇頂點。如果選擇的是邊線,Onshape 會根據為另一邊做出的選擇來找出頂點。您可以自行選擇邊線來取代 Onshape 做出的選擇。

In addition to the surfacing tools, curves are used to create the basic building blocks of surfaces.
這個清單是曲線特徵工具的集合,並非詳盡的清單。在操控曲線時,可能會使用其他的特徵工具。
- 草圖工具 - 草圖工具列中的工具,像是直線、轉角矩形、中心點矩形、中心點畫圓、三點畫圓、切線弧、三點定弧、樣條、點與建構線,可用來建立 Part Studio 中的草圖。
-
螺旋線 - 使用圓錐或圓柱面、單一軸或結合連接器的 z 軸、或是環狀邊線來建立螺旋線。
-
3D 擬合樣條 - 建立穿過連續頂點的 3D 擬合樣條。建立列在零件清單中「曲線」之下的曲線。
-
投影曲線 - 建立一條來自兩個草圖投影的曲線 (「兩個草圖」選項),或是建立一條來自曲線投影至面的曲線 (「曲線到面」選項)。
-
橋接曲線 - 建立連接任兩個點、頂點或結合連接器的一條曲線。所產生的曲線會列於「特徵」清單與「零件」清單中。
-
複合曲線 - 以一條曲線來代表多條邊線。選擇多條相鄰的邊線、草圖圖元、與其他的曲線。選擇非連續的邊線會建立多條的曲線。為每條曲線做出的選擇項目必須在其頂點處交會 (曲線會列於「零件」>「曲線」清單之中)。
-
相交曲線 -在兩或多個曲面或面的相交處建立一條曲線。選取的項目必須是相交的。
-
修剪曲線 -根據距離修剪或延伸曲線,或是修剪或延伸至邊界圖元。
-
等傾線 - 在斜面上建立一條等傾線。等傾線會出現在面相較於其參考定義有某些傾斜的位置。所產生的等傾線會列於「特徵」清單與「零件」清單中。
-
偏移曲線 - 藉由在周圍面上偏移邊線來建立與延伸和/或分割新的曲線。
-
等參數曲線 - 建立沿面或曲面的 U 方向或 V 方向延伸的平滑曲線。
-
編輯曲線 - 選擇草圖圖元或曲線來套用簡化的近似、提高度數、重新定位控制曲線頂點和/或平化至任何 2D 平面來編輯現有的曲線。
-
路線曲線 - 建立在 3D 空間中跨越一個或多個平面的多點曲線 (路線路徑)。這對於建立管路路線、配線、以及進階曲面建立中的 NURBS 曲線是非常有用的。
