Re: part studio granularity best practices and refactoring
Here is an improvement request you can vote on for Copy And Paste Features.
Here is the best place to learn best practices and how to use onshape most efficiently:

And this video by @EvanAReese will give you a huge boost with understanding when to refactor your studios and when to keep prototyping.
Re: rotate face up to vertex?
I've also searched for this functionality in the past but didn't find it. What I ended up doing was creating a guide sketch on the side and measuring the estimated angle. Then I used that estimated angle variable to drive the move face angle.
There are a few other more complicated ways I can think of, but this was the quickest.
Re: How to limit rib length
You could also add a split face and delete face after the fact…
Not ideal but dealing with unexpected results/limitations should also be part of teaching (and that's a good workflow to know anyway)!
Re: evCollision doesn't seem to work
Hi there! You're right, evCollision is quite tricky to use correctly and our documentation is a bit limited. I have filed a documentation bug for evCollision. In the meantime:
Your testbed is very elegant but doesn't cover all of the possible topological types.
EXISTS: In Onshape we have several things you might think of as "edges" (edge of a body, line in a sketch, curve) but under the hood these aren't all the same. Sometimes we create what's called a "wire body" to represent an edge. A wire body is a body but it has only 1 dimension.
You can "get to" the body specified by a sketch edge (through filtering) or creating curves and select them.
For collisions between two 1-dimensional bodies, does containment mean anything? Does abutment? (They don't, but it took me a bit to think through this). Because these concepts don't mean anything, we the parasolid kernel just returns EXISTS. Here's a screen showing the result of an evCollision between two curves:

Re: Graham Escapement Relation
This is a typical example of an intermitting movement and unfortunately this cannot be animated straight away in Onshape.
However, there is a workaround: animation with timelines and pointers.
This method is invented by @john_mcclary.
I recently published a demonstration and explanation of a simplified animation I did on one of my projects.
You may study the document to get the results you want.
If you have any questions I will be glad to help you.

Re: Is there a way to edit or delete a "version"?
Still waiting for a hide/delete button…
