We currently manufacture many parts like the one attached.  Essentially 2 hollow cylinders for which the parting plane runs through the axis of both cylinders.  We currently create our tooling using cavity and a series of split commands.  Are parts of this fashion able to make use of the sequence outlined in the mold tutorial?

I've tried and I can't get it to work - any input is appreciated.
