I talked with another ESRI Support person and he told me the same stuff you did about vertex editing and ModelBuilder. I was able to create a ModelBuilder for the first 3 actions, but part of me wonders what's the use if they're that simple to do, even for a large county and its roads (i.e. LA County). That's another discussion.
What I'm curious about now is that I am going File--Add Data--Add Route Events, using a calibrated roads layer which I believe has perfectly good geometry, adding an event table, using the correct Begin and End fields, and I end up with a layer that is missing vertices and whole roads as well! Even a section where I edited the vertices during Route Measure Editing didn't mess up! I did at one point take a look at the Route Table I had and fixed up things here and there and the coverage got better, but things that I didn't think would screw up, did!
Here are some screen shots of what I'm talking about.
I will admit at one point I went back to the Events table I have and edited some names of the routes and that helped some, and on another try I got roads to show up that aren't right now. Something is really bizarre here, because I never had this problem before?!
