Join

Join 指令将端点或边缘相连接的单一物件组合在一起。

直线组合为多重直线，曲线组合为多重曲线、曲面或多重曲面组合为多重曲面或实体。

附注

• Join 指令不会更改几何信息，它会测试要组合物件的连接处距离是否小于公差的两倍，如果小于就组合在一起，如果大于，就不组合。
• 当首先选择曲线或使用子物件选择时，可以将曲面边缘或网格边缘与曲线组合起来以创建多重直线或多重曲线。
• 您可以组合端点相连接的曲线。
• 组合后物件所在的图层是由选取物件的顺序决定的。
• 曲面或多重曲面相接的外露边缘可以组合在一起。
• 您可以将不相连接的网格（未相接的网格）组合在一起。
• 曲面组合后的几何信息不会改变，只是把相接的曲面"黏"起来，使网格转换、布尔运算与交线可以跨越曲面而不产生缝隙。
• 变更曲面几何信息填补缝隙可以使用 MatchSrf 指令。加入曲面填补缝隙可以使用 FilletSrf、BlendSrf、BlendEdge、FilletEdge、NetworkSrf 或 Patch 指令。
• 如果您想将两个曲面合并成一个曲面可以使用 MergeSrf 指令，请注意平滑选项的设定，得到您想要的结果。
• Degrees and control points will not change when curves with different degrees are joined.

Command-line options

Undo

The Undo option removes the last selected object from the join operation.

JoinDisjointMeshes = Yes | No

The JoinDisjointMeshes option allows joining meshes that do not touch into one object.

• Naked mesh vertices within Absolute tolerance will be aligned.

See: SplitDisjointMesh command.

SubDJoinedEdges = Yes | No

Specifies how SubD edges are joined.

Smooth	Crease

• SubD objects will merge into a single SubD that cannot be exploded.

• Overlapped SubD control polygons will merge when possible.

  

SubDSymmetry = Preserve | Discard

When joining a SubD created by the Reflect or Symmetry command to other SubDs, and the outcome is symmetrical, this option determines whether the Reflect or Symmetry link will be preserved or discarded on the joined SubD.

A Reflected-SubD is joined to other SubD with SubDSymmetry=Preserve.

Hidden command-line options

SelChain

Selects connected curves or edges based on continuity conditions.

JoinCopy

 History enabled

The JoinCopy command duplicates the selected objects and joins the duplicates.

JoinCopy and Join commands are technically identical. The only difference is JoinCopy does not delete input objects.

The Undo option removes the last selected object from the join operation.
