Until you have that "aha"-moment-- and you will, if you have enough motivation to stick with it-- Workplanes will seem a nebulous concept. Then-- after that light-bulb comes on-- you will not know how you couldn't/didn't conceptualize them in the first place.
I just came across this video
*, posted here
by Rip Fowler. It should be a good start.
But you do just have to play with it until that "aha"-moment. Maybe try to draw something real-world
that's simple. Something you have lying around that you can reference and measure.
I suggest, to aid you: Via the Customize windows/pages, activate the Workplane toolbar and place it somewhere easily and quickly accessible (I leave mine floating
when I'm drawing 3D) and the Standard Views toolbar as well (which I also leave floating); in the video, Rip has them as Pop-Ups at the top of his Local Menu-- those toolbars is what he's working with
. Work in the Standard Isometric Views-- or switch to them from the Standard Orthograpic Views-- as much as possible.
Also, via Menu Bar->Workspace, turn on "User Coordinate System" (& "World Coordinate System")
and pay attention to where it is and its orientation as you experiment with the Workplane tools. The "World Coordinate System" is built in stone, is part of the inner-workings of the CAD system, and cannot be changed; it is upon this "World Coordinate System" that all other coordinates and Coordinate Systems (Workplanes) will be based. The "User Coordinate System" is essentially the current Workplane, the active Workplane/Coordinate system you create as you are drawing, or: the Workplane/Coordinate System that becomes active when you Select a pre-drawn object with your Selector Tool in "2D Selector Mode" and that object resides on a different Workplane than the current active Workplane (you might want to re-read that... slooowwwly).
----[EDIT]: I just watched Rip's video that I posted the link to. Unfortunately, although well-intentioned I'm sure, it doesn't seem to be "for dummies". I'm new enough to drawing in 3D that I totally remember having no clue as to what Workplanes are, how to set them, and how to work with them. It's just very difficult to explain the concept of Workplanes to someone brand new to them without being physically present with the student. You're just going to have to (frustratingly) work with them, I guess.
Like most things in Life: It really just comes down to how motivated you are.
