Width Mates

A width mate centers a tab within the width of a groove.

Groove width references can include:

  • Two parallel planar faces

  • Two non-parallel planar faces (with or without draft)

Tab references can include:

  • Two parallel planar faces

  • Two non-parallel planar faces (with or without draft)

  • One cylindrical face or axis


To add a width mate:

  1. Click Mate (Assembly toolbar) or Insert, Mate.

  2. Under Advanced Mates, click Width .

  3. Under Mate Selections:

    1. Select two planar faces for Width selections .

    2. Select two planar faces, or one cylindrical face or axis, for Tab selections .

  4. Click .

The components align so that the tab is centered between the faces of the groove. The tab can translate along the center plane of the groove and rotate about an axis normal to the center plane. The width mate prevents the tab from translating or rotating side to side.
