Hi Hydromech I think your description is the one to make the datum plane coupled with the sketch/extrusion, and subsequently hiding it, but it will still be visible within the tree, and you can still hide/unhide it.
What's happening is i'm trying to (and found others' PRT models that have done...
Here's a scientist's web page, he's done a fair amount of ProE modelling. You can just follow the actual PRT models to practice!

PS everyday household products make good project starters.
I'm trying to work out how to make datum planes invisible:
How to make datum plane specific to a certain sketch/feature hidden within the model tree and the layer tree,so that only when you edit the sketch will you see that particular datum plane actually exist (i.e. sketch-"sketch plane"...
