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


  • 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.

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

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



  • 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.
