修剪曲線

1. Click the Trim curve icon () on the feature toolbar:

   

2. 在已選取「修剪」的情況下，於圖形區域中選擇一或多條曲線。

3. 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:

     

     曲線 (左圖) 修剪至方塊面 (右圖) 的範例。

   • 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:

     

     曲線 (左圖) 修剪至結合連接器 (右圖) 的範例。

可以組合使用圖元與結合連接器。

4. 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。
5. Optionally, click the Opposite direction icon () to select the opposite section of the curve to trim:

   

   將曲線修剪至另一曲線。強調顯示經修剪的曲線與輔助點 (左圖)。使用相反方向箭頭，會從相反方向修剪曲線 (右圖)。

6. Click the checkmark ()

1. Click the Trim curve icon () on the feature toolbar:

   

2. 選擇 [延伸]。
3. 在圖形區域中選擇一或多條曲線。

4. 選擇一個終止形態，可以是：

   • Blind - Extends the curve a specific length (as entered in the distance field):

     

     曲線 (左圖) 任意延伸 (右圖) 的範例。

   • Up to entity - Extends the curve to one or more entities (curve, face, edge, or plane). The curve must intersect the entity:

   

   曲線 (左圖) 延伸至方塊面 (右圖) 的範例。

5. Select the extension shape, either:
   • Curvature - Attempts to match the curvature of the specified curve while extending.
   • Tangent - Extends the curve while maintaining tangency.
6. 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。
7. Optionally, click the Opposite direction icon () to extend the curve in the opposite direction.

   

   左圖中有兩條曲線。其中一條曲線根據距離延伸 (在中間圖片強調顯示曲線與輔助點)。使用相反方向箭頭，從曲線的另一端延伸曲線 (右圖)。

8. Click the checkmark ()

• 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.
• Routing curve - Create a multi-point curve across one or more planes in 3D space (routed path). This is useful for creating pipe routing, wiring, and NURBS curves for advanced surfacing.
