Offset 指令以特定距离偏移复制一条曲线。
指令行选项
距离显示
Sets the offset distance.
角
Specifies how offset corner continuity handled. These options only apply if the offset direction is to the "outside" as shown in the image.
Original curve (blue). Offset to outside (red). Offset to inside (green).
锐角
Curves offset to the outside of a corner will be extended to meet at sharp corners with position (G0) continuity.
Round
Curves offset to the outside of a corner will be filled with arc segments with tangent (G1) continuity.
Smooth
Curves offset to the outside of a corner will be filled with blend segments with curvature (G2) continuity.
Chamfer
The corners of the offset curves will be filled with a straight line between their endpoints.
通过点
Offsets through a picked point instead of at a distance.
公差
Sets the tolerance for the offset curve.
Type 0 to use the default system tolerance.
两侧
Offsets the curve on both sides of the input curve.
与工作平面平行
通过此选项，在当前的工作平面上偏移曲线，而不使用原始曲线所在的平面偏移曲线。
Cap
将原来的曲线与偏移曲线的两端封闭。
无
不封闭曲线的两端，偏移曲线会建立在目前的图层。
平头
以直线将输入的曲线与偏移的曲线的两端组合，得到的多重曲线会建立在输入的曲线的图层上。
圆头
以正切的圆弧将输入的曲线与偏移的曲线的两端组合，得到的多重曲线会建立在输入的曲线的图层上。
