A width mate centers a tab within the width of a groove.
Groove width references can include:
Tab references can include:
Two parallel planar faces
Two non-parallel planar faces (with or without
One cylindrical face or axis
To add a width mate:
(Assembly toolbar) or Insert,
Mates, click Width .
Under Mate Selections:
Select two planar faces for Width
Select two planar faces, or one cylindrical
face or axis, for Tab selections
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.
