Where can I find this command?
ExtrudeCrvAlongCrv 指令可將曲線沿著另一條曲線擠出建立曲面。
Notes
| ● | 非平面的曲線 - 使用中作業視窗的工作平面 Z 軸為預設的擠出方向。 平面曲線 - 與曲線平面垂直的方向為預設的擠出方向。 |
| ● | Unlike Lofts and Sweeps, the initial orientation of the profile curve or surface is maintained through the extrusion. |
| ● | 如果輸入的是非平面的多重曲線，或是平面的多重曲線但擠出的方向未與曲線平面垂直，建立的會是多重曲面而非擠出物件。 |
實體
如果擠出的曲線是封閉的平面曲線，擠出後的曲面兩端會各建立一個平面，並將擠出的曲面與兩端的平面組合為封閉的多重曲面。
刪除輸入物件
是
Deletes the original geometry.
No
Retains the original geometry.
SubCurve
The SubCurve option extrudes a curve the distance specified by picking two points along a curve.
Note: The extruded surface starts from the beginning of the curve, not the first picked point. Picking the points only establishes the extrusion distance.
SplitAtTangents=Yes/No
The Yes option creates a single surface.
The No option creates a polysurface when the input curves are joined tangent curves. Faces in the resulting polysurface correspond to the tangent sub-curves in the input curves.
原來的多重曲線 (左)、在正切點分割=否 (中)、在正切點分割=是 (右)。
附註
| ● | When this option is used, the output will be a polysurface. |
| ● | When UseExtrusions is on, this setting has no effect. |
