Sweep2 指令旨在沿着两条路径扫掠通过数条定义曲面形状的断面曲线建立曲面。

Curve options
Do not change cross sections
Creates the sweep without altering the cross-section curves.
Rebuild cross sections with ___ control points
Rebuilds the cross-section curve's control points before creating the sweep.
Refit cross sections within ___
Refits the cross-section curves before creating the sweep.
Preserve first cross section
使用正切或曲率连续计算扫掠曲面边缘的连续性时,建立的曲面可能会脱离输入的断面曲线,这个选项可以强迫扫掠曲面的开始边缘符合第一条断面曲线的形状。
Preserve last cross section
使用正切或曲率连续计算扫掠曲面边缘的连续性时,建立的曲面可能会脱离输入的断面曲线,这个选项可以强迫扫掠曲面的开始边缘符合第一条断面曲线的形状。
Maintain height
Removes the association between the height scaling from the width scaling. By default, cross-section curves normally scale in both the height and width dimensions.
启用
关闭
Refit rails
Refits the rail curves before creating the sweep.
Edge continuity
Continuity is only enabled if the rails are surface edges and the shape curves are non-rational, that is, all control point weights are 1. Exact arcs and ellipse segments are rational.
Note: Only continuity options that the curve structure (point count and rational/non rational) supports will be available.
位置 / 正切 / 曲率
设定边缘的连续性。
Closed sweep
封闭扫掠 当路径为封闭曲线时,曲面扫掠过最后一条断面曲线后会再回到第一条断面曲线。
附注: 您至少需要选取两条断面曲线才能使用这个选项。
加入额外的断面曲线,控制曲面断面结构线的方向。
