Photography Studio Setup Diagram

PLEASE help me with my lighting diagrams!? (photography) I'm not sure how to set them out - what does what!?

I want to show the lighting setup for studio photos that are fairly bright but have a slight shadow from one side, using various softboxes and reflectors.
please please please help me, i'm completely clueless!

how can I do something I have no idea how to do?
This is a general procedure for analyzing the lighting configuration of any given photograph. If you know how shadows work, then you would put the light source opposite the shadow. The size of the light source (softbox, umbrella, grid spot, snoot, bare tube, in order from largest to smallest) will determine how soft the edges of the shadow are.
Look for evidence of secondary, tertiary, quaternary, etc. light sources (used as fill lights) and determine whether they were actual lights or just reflectors.
That's pretty much all there is to it. If you have the opportunity to work with this kind of lighting, by all means do so. You will learn so much more from practice than you will from theory.
I hope this helps! Good luck!
