   This sketch contains a fully constrained profile with six dimensions and two collinear constraints. One dimension and one collinear constraint position the T Slot geometry on the face of Extrusion1 and are of no further interest. Two of the dimensions use an equation to position the T Slot width one half of the distance from a vertical construction line. These two equations ensure that any values added will produce a symmetrical slot.
