This post is a collection of related topics on polygon selection from the AUTODESK MAYA HELP . Click on the links below to read the access the full Help content on Autodesk website.

Merge

• Merge boundary edges
  • You can only merge edges that are part of the same polygon mesh.

  • Mesh Tools > Target Weld
    or
    

  • Shift+RMB on an edge and select Merge/Collapse Edges > Target Weld Tool.

    • Tip! MMdrag to merge components to center.
    • Tip! Press Y to reactivate the Target Weld Tool after switching to another tool.
• Merge vertices, edges, or faces into one vertex

  • Edit Mesh > Merge
    Edit Mesh > Merge to Center
    or
    Shift+RMB > Merge Vertices

    • Set the Threshold value to control how close edges must be to merge
    • To make it easier to distinguish between border edges and interior edges, turn on the display of border edges by selecting Display > Polygons > Border Edges.
    • You cannot merge non-manifold edges.
    • Merging vertices can make your geometry non-manifold. Use Mesh > Cleanup to fix non-manifold geometry.

Collapse

Collapsing Edes

• Edit Mesh > Collapse

Bridge

• Bridge between border edges

• Edit Mesh > Bridge

  • Troubleshoot bridged meshes

Fill holes

1. Select the border edge you want to fill.
   • To highlight border edges, select Display > Polygons > Border Edges.
2. Mesh > Fill Hole

Fill holes with Quad Draw

1. Set a reference mesh for Quad Draw
2. Drop dots with Quad Draw
3. Create polygons with Quad Draw
4. Refine polygons with Quad Draw
