OffsetMultiple 指令可以复制多条曲线，复制得到的曲线都和原始曲线保持指定的距离。
附注
- 所有开放曲线向鼠标指针设置的方向偏移。
- 偏移封闭曲线时，如果偏移方向选在其中一条曲线的内部，其他封闭曲线也会向其内部便宜。
- 对于闭合曲线内部的其他闭合曲线，偏移方向和它的“容器”（容纳它的闭合曲线）偏移方向相反。
步骤
- 选取曲线和曲面边缘。
- 在其一侧点击。
为达到良好的效果，曲线偏移距离应适当小一些，并采用光滑曲线，否则偏移曲线可能会有自交的情形。
指令行选项
距离
设置偏移距离。
Loose
Yes - Offsets a curve by moving its edit points.
- Polycurve segments offset individually. Segments will break apart at corners in the result.
- The Corner and Tolerance options are not used and are not shown.
- Curves with fewer edit points may distort more in the result.
The output curve has the same parameter structure as the input curve.
No - Offsets the curve shape within the Tolerance setting.
- A small tolerance creates an output curve with more control points.
Corner
Specifies how corners are handled when they are offset to the "convex" side as pointed out in the image.
Original curve (blue). Offset curve (red).
Sharp
Extend the adjacent offset segments to form a sharp corner.
Round
Fill the gap between adjacent offset segments with a tangent arc segment.
Smooth
Fill the gap between adjacent offset segments with a degree 3 tangent segment.
Chamfer
Fill the gap between adjacent offset segments with a straight segment.
None
Leave the gap open between adjacent offset segments.
偏移次数
设置要偏移并创建几条曲线。
