    About Modifying Mesh Faces

    Split, extrude, merge, collapse, or spin mesh faces to modify their shapes.

    Split a Mesh Face

    You can split a mesh face to make custom subdivisions. Use this method to prevent
    deforming a larger area for small modifications.

    Because you specify the start point and end point of the split, this method also gives
    you control over the shape of the two new faces. Use the Vertex option to snap automatically
    to the vertices of the face. If you plan to split a face to create—and then spin the
    edge of—two triangular faces (MESHSPIN), use the Vertex option to ensure precision.

    Extrude Mesh Faces

    You can add definition to a 3D object by extruding a mesh face. Extruding other types
    of objects creates a separate 3D solid object. However extruding a mesh face extends,
    or deforms, the existing object and subdivides the extruded face.

    You can use the same methods for extrusion of the faces of 3D solids and meshes as
    you use for other types of objects. For example, you can specify an extrusion direction,
    a path, or a taper angle. However, when you extrude mesh faces, the MESHEXTRUDE command
    provides an option that sets whether adjacent faces are extruded individually or whether
    their shared edges remained joined.

    You cannot create joined extrusions for mesh faces in which only the vertices are

    Reconfigure Adjacent Mesh Faces

    You can extend your editing options by reconfiguring adjacent faces. Several options
    are available:

    • Merge adjacent faces. Combine adjacent faces to form a single face. Merging works best with faces that
      are on the same plane.

      Although you can merge faces that wrap a corner, additional modifications to the resulting
      mesh object can have unexpected results.

    • Collapse the mesh vertices. Merge adjacent vertices of surrounding faces form a single point. The selected face
      is removed.

    • Spin edges of triangular faces. Rotate an edge that is shared by two triangular faces. The shared edge spins to extend
      from the opposite vertices. This activity works best when the adjoined triangles form
      a rectangular, not a triangular, shape.
