Hi FiL, well with a complex model with 70-100 objects you can still temporarily simplify that by hiding other objects so that you only have a few visible on the screen to work with. Then the simple mechanisms can still be applied.

One quick way to hide other objects it to select the few that you are interested in, and then right-click on the Edit > Hide button. That will do an "Isolate" of those selected objects and make them the only ones showing. When you are done working on them right-click again on the Hide button to restore back to the pre-Isolate state.

It's pretty important to try and hide things that are getting in your way earlier in your workflow rather than wasting too much time struggling with a cluttered screen.

Of course in some situations you may be trying to work on a bunch of things at once, but the more that you can break things down into simple things at a time really helps.
