This one is giving me fits also.

I have 2 parts in an assembly. The 2 parts are always named differently along with the assembly name. One of the parts we make a sketch on, for accuracy of cutting, and call it "Locating Sketch".

Once in the assembly, the other part is selected (the one that doesn't have the "Locating Sketch"), start a sketch on one of its faces, select the "Locating Sketch" on the other part, convert entity, and Cut-Extrude to a depth of .25"

I have this so far, but I am getting confused. Please help!
