相交曲線

在圖形區域中有兩或多個相交曲面或面的情況下：

1. 按一下 。

   

2. 系統會自動強調顯示「群組 1」。 群組是建立相交的曲面和/或面的集合。在圖形區域中選擇第一組的曲面和/或面。
3. 在對話方塊中選擇「群組 2」。
4. 在圖形區域中選擇第二組的曲面和/或面。

5. Complex curves can be reapproximated to create simpler curves. Check Approximate to open options to reapproximate the curve. The original curve is displayed in orange, and the new approximated curve is displayed in magenta.

   • Target degree - Enter the target curve degree for the selected curve.
   • Maximum control points - Enter the maximum number of control points allowed for the selected curve.
   • Tolerance - Tolerance of the selected curve, as a length measurement. Enter the tolerance value.
   • Keep start derivative - Check to keep tangency at the beginning of the selected curve.
   • Keep end derivative - Check to keep tangency at the ending of the selected curve.
   • Show deviation - Check to view the maximum deviation between the original curve and the reapproximated curve.

   

6. 按一下 來接受。

在同一群組內圖元間的相交不會產生曲線，僅會在「群組 1」與「群組 2」間的相交才會產生。

取決於「群組 1」與「群組 2」的選取項目，可以建立多於一條的曲線。

兩個相交曲面可建立 3 條曲線的範例

使用零件 (曲線) 清單中的眼睛圖示來隱藏/顯示曲線。

• 如果您從一條相交曲線建立「線性複製排列」，可能不會沿曲面建立曲線。如果您是要沿著曲面建立曲線，請開啟「線性複製排列」特徵對話方塊，接著在「要複製排列的特徵」中加入用做相交的平面，然後核取「重新套用特徵」。

  

除了曲面建構工具之外，還可使用曲線來建立曲面的基本建構塊。

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.
