Join

Connects objects together to form a single object: lines into polylines, curves into polycurves, surfaces and polysurfaces into polysurfaces or solids.

Steps:

• Select the objects (curves, surfaces,  polysurfaces, or meshes) to join.

Note: Use SelChain to select a string of curves that touch end to end.

To select objects one by one

1. Select an object (curve, surface,  polysurface, or mesh).

2. Select the next object.

Note: To select a surface edge as a curve to join, see sub-object selection.

3. When you are finished selecting objects to join, press Enter.

Notes

• You can join curves that are arranged sequentially.

• You can join surfaces and polysurfaces that touch at naked edges. The result is always a polysurface which you can explode into separate surfaces.

• Joining does not change the underlying geometry. It simply "glues" adjacent surfaces together so meshing, Boolean operations, and intersections can go across the seam 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 FilletSrf, BlendSrf, BlendEdge, FilletEdge, 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.
