Default Mate Types

When you select cylindrical faces or circular edges to mate with an axis, the software creates a concentric mate. When you select two parallel planar faces, the software creates a coincident mate.

Some default mate types have a secondary default mate that is created when the primary default mate type coincident mate over-defines the assembly. For example, the software creates a parallel mate between two planar parallel faces when a coincident mate over-defines the assembly.

To mate an axis with a cylindrical face in an assembly:


  1. Select an axis and a cylindrical face or circular edge.
    To display temporary axes, expand Hide/Show Items (Heads-up View toolbar) and click View Temporary Axes .
  2. Click Mate (Assembly toolbar) or Insert > Mate.
    The mate defaults to a cylindrical mate.


  3. Complete the mate and click PM_OK.gif.
