OffsetSrf 指令以等距离偏移复制曲面或多重曲面。

选项

距离显示

设定偏移的距离。

角

圆角

锐角偏移产生的缝隙以圆角填补。

锐角

锐角偏移时曲面延伸相互修剪。

全部反转

反转所有选取的曲面的偏移方向，曲面上箭头的方向为正的偏移方向。

实体

以原来的曲面与偏移后的曲面边缘放样并组合成封闭的实体。

松弛 (仅适用曲面)

偏移后的曲面的结构与原来的曲面相同。

公差

设定偏移曲面的公差，输入 0 为使用预设公差。

两侧

同时往两侧偏移。

删除输入物件

是

将原来的物件从文件中删除。

否

Retains the original geometry.

Troubleshoot shelling

Shell and OffsetSrf for polysurfaces are works in progress. There are several known problem areas:

●

Singular surfaces can cause problems, especially when the offset of the surface must be extended at the singularity. The extensions are done in OffsetSrf (Corner=Sharp) and shelling, which always uses sharp corners. These extensions happen when the offsets of adjacent surfaces come apart. Also, cone-like singularities cause problems in all cases.

●

Complex vertices (ones with more than three edges) can be problematic, especially in shelling and sharp corner offsets and where some, but not all, of the surfaces at the vertex offset apart.

●

OffsetSrf on polysurfaces with naked edges, where the naked edges make concave boundaries will not work correctly.

●

If faces adjacent to the removed faces offset in such a way that the removed face must be extended to fill in the gap, it will fail. Remove surface (x).

●

Any surface whose offset self-intersects will cause a problem.
