Join

The Join command connects objects together to form a single object.

Join turns lines into polylines, curves into polycurves, surfaces and polysurfaces into polysurfaces or solids.

• Join objects
• Command-line options

Join objects

Steps:

1. Select an object (curve, surface, polysurface, or mesh).
2. Select the next object.
3. When you are finished selecting objects to join, press Enter.

Command-line options

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

Notes

• Join does not change the surfaces. It is merely a test to see if the surfaces edges are within 2x tolerance. If they are, then they are tagged as joined and not available for further joining.
• You can join curves that touch end-to-end.
• The order the objects are selected determines the layer of the new joined object.
• You can join surfaces and polysurfaces that touch at naked edges.
• Joining does not change the underlying surface geometry. It simply "glues" adjacent objects together so meshing, Boolean operations, and intersections can cross seams without gaps.
• To change a surface's geometry so it fills in a gap, use MatchSrf or fill the gap with a new surface created by FilletSr, NetworkSrf, or Patch.
• To change two adjacent surfaces into a single surface, use MergeSrf. Pay special attention to the setting of the Smooth option to get the geometry you want.
• Degrees and control points will not change when curves with different degrees are joined.
