根據距離修剪或延伸曲線,或是修剪或延伸至邊界圖元。
根據距離修剪或延伸曲線,或是修剪或延伸至邊界圖元。
在特徵工具列中:
修剪曲線特徵可讓您根據距離修剪或延伸一或多條曲線或是將曲線修剪或延伸至邊界圖元。
按一下 Part Studio 工具列中的「修剪曲線」特徵工具。如果尚未選取,請在對話方塊中選擇 [修剪]。
在圖形區域中選擇一條曲線。在對話方塊中按一下「成形至圖元」欄位,然後在圖形區域中選擇要修剪至的邊界 (曲線、面、邊線或平面)。曲線必須與圖元相交。或者也可以將曲線修剪至一或多個現有的結合連接器。如果沒有結合連接器存在,按一下「結合連接器」圖示來建立一個新的隱含結合連接器。曲線不需要與結合連接器相交。
選擇性地選取點一個輔住點來引導曲線要修剪至何處。系統會將曲線修剪至最靠近輔助點的位置。
選擇性地按一下「相反方向」圖示來選擇修剪曲線的另一端。
按一下核取記號來接受新的修剪曲線。
- 按一下特徵工具列中的「修剪曲線」圖示 ():
- 在已選取「修剪」的情況下,於圖形區域中選擇一或多條曲線。
-
選擇要如何修剪曲線,可以是:
- Up to entity - Trims the curve to one or more entities (curve, face, edge, or plane). The curve must intersect the entity:
- Up to one or more existing Mate connectors. If one does not exist, click the Mate connector icon () to create a new implicit Mate connector. The curve does not need to intersect the Mate connector:
- 選擇性地選取點一個輔住點來引導曲線要修剪至何處。系統會將曲線修剪至最靠近輔助點的位置。
- Optionally, click the Opposite direction icon () to select the opposite section of the curve to trim:
- 按一下核取記號 ()
可以組合使用圖元與結合連接器。
修剪曲線特徵可根據距離延伸曲線或是將曲線延伸至邊界圖元。
按一下 Part Studio 工具列中的「修剪曲線」特徵工具。在對話方塊中選擇 [延伸]。
在圖形區域中選擇一條曲線。在對話方塊的「輔助點」欄位中按一下。然後選擇沿著曲線的一個點,例如,曲線端點。系統會將曲線延伸至最靠近所選點的位置。使用「給定深度」為終止形態,在「距離」欄位中輸入一個距離值以決定曲線要延伸的距離。
選擇性地按一下「相反方向」箭頭來從曲線的另一端延伸。
選擇延伸的形狀。「曲率」會在延伸時嘗試與特定曲線的曲率配合。「相切」則會在維持相切的同時延伸曲線。
如果需要,可以選擇「成形至圖元」的終止形態,這樣會將曲線延伸至一或多個圖元 (曲線、面、邊線或平面)。曲線必須與圖元相交。或者也可以將曲線延伸至一或多個現有的結合連接器。如果沒有結合連接器存在,按一下「結合連接器」圖示來建立一個新的隱含結合連接器。曲線不需要與結合連接器相交。

- 按一下特徵工具列中的「修剪曲線」圖示 ():
- 選擇 [延伸]。
- 在圖形區域中選擇一或多條曲線。
-
選擇一個終止形態,可以是:
- Blind - Extends the curve a specific length (as entered in the distance field):
- Up to entity - Extends the curve to one or more entities (curve, face, edge, or plane). The curve must intersect the entity:
- Select the extension shape, either:
- Curvature - Attempts to match the curvature of the specified curve while extending.
- Tangent - Extends the curve while maintaining tangency.
- 選擇一個輔助點以決定要從曲線的那一端延伸。輔助點不一定要在曲線上。當選取了一個點時,會延伸最靠近該點的曲線端。
- Optionally, click the Opposite direction icon () to extend the curve in the opposite direction.
- 按一下核取記號 ()
-
To modify sketch entities, first convert them to composite curves.

相反方向箭頭與輔助點是不相關的;可以選擇相反方向而不選擇一個輔助點。
In addition to the surfacing tools, curves are used to create the basic building blocks of surfaces.
This lists the collection of curve feature tools. This is not an exhaustive list. Additional Feature tools may be used when manipulating curves.
- Sketch tools - Tools in the Sketch toolbar such as Line, Corner rectangle, Center point rectangle, Center point circle, 3 point circle, Tangent arc, 3 point arc, Spline, Point, and Construction used to create a sketch in a Part Studio.
- Helix - Create a helix using a conical or cylindrical face, single axis or z-axis of a mate connector, or circular edge.
- 3D fit spline - Create a 3D fit spline through a series of vertices. Creates a curve which is listed in the Parts list under Curves.
- Projected curve - Create a curve from the projection of two sketches (Two sketches option) or from the projection of a curve on a face (Curve to face option).
- Bridging curve - Create a Curve connecting any two points, vertices, or Mate connectors. The resulting Curve is listed in the Feature list and the Parts list.
- Composite curve - Represent multiple edges as one Curve. Select multiple adjacent edges, sketch entities, and other curves. Selecting non-contiguous edges may result in multiple Curves created. Selections for each Curve must meet at their vertices. (Curves are listed in the Parts > Curves list.)
- Intersection curve - Create a curve at the intersection of two or more surfaces or faces. The selections must intersect.
- Trim curve - Trim or extend a curve by a distance or to a bounding entity.
- Isocline - Create an isocline on a sloped face. An isocline runs on a face at positions where the face has a certain slope compared to its reference definition. The resulting isocline is listed in the Feature list and Parts list.
- Offset curve - Create and extend and/or split a new curve by offsetting edges on surrounding faces.
- Isoparametric curve - Create smooth curves that run along a face or surface in the U or V direction.
- Edit curve - Edit an existing curve by selecting sketch entities or curves to apply a simplified approximation, elevate the degree, reposition control curve vertices and/or planarize into any 2D plane.
