Width Mates

A width mate constrains a tab between two planar faces.

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. Under Advanced Mates, select one of the following constraints:


    Centers a tab within the width of a groove. This is the same functionality as in previous releases.


    Lets the components move freely within the limits of the selected faces or planes with respect to the components.


    Sets a distance or angle dimension from one selection set to the closest opposing selection set of faces or planes.


    Sets the distance or angle based on a percentage value dimension from one set of the selection set to the center of the other selection set.

  5. Click .

    The components align so that the tab is mated 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.
