Width Mates

A width mate constrains a tab between two planar faces.

Width references can include:
  • Two parallel planar faces
  • Two nonparallel planar faces (with or without draft)
  • One cylindrical face or axis
Examples:

To add a width mate:

  1. Click Mate (Assembly toolbar) or Insert > Mate.
  2. On the Advanced tab, click Width .
  3. Under Mate Selections:
    1. Select two planar faces, or one cylindrical face or axis, for Width selections 1.
    2. Select two planar faces, or one cylindrical face or axis, for Width selections 2.
  4. Under Mate Type, select a constraint:
    Option Description
    Centered Centers a tab within the width of a groove.
    If the distance for the width selections are equal, only the Centered constraint is available.
    Free Moves components freely within the limits of the selected faces or planes with respect to the components.
    Dimension Specifies a distance or angle dimension from one selection set to the closest opposing selection set of faces or planes.
    Percent Specifies 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.
