Attach subdivision surfaces
 
 
 

The edges of the surfaces will attach only if each surface has the same number of polygonal edges at the base mesh level (level 0). If the surface does not have the same number of edges, the objects are grouped, but the vertices and edges of the surfaces do not merge.

Attaching will destroy any deformer weighting on the selected surfaces.

To prepare subdivision surfaces to be attached

  1. Make sure the two surfaces you want to attach each have the same number of polygonal edges at the base mesh (level 0). If they do not have the same number of edges, the surfaces will be grouped, but will not merge.

    Use Split Polygon or Delete Edge on the polygon proxy to create or remove edges.

To attach subdivision surfaces

  1. Select the surfaces you want to attach.
  2. Select Subdiv Surfaces > Attach.
