Try to screen out irrelevant dimensions, like the ones on the hook thing.
Ill second Cad on this one, that thing is a mess!

just a little tip of advice, Get to know cad, you wont find a job in the industry if you are horrible with cad.

When drawing that mess it will be very easy to get lost.

Buy some colored pencils. color the centerlines in basic colors blue, green, red and stuff

Draw in autocad using the same colors

As the drawing progresses and you can see enough of it not get lost, change all lines to white as a way to conserve colors because you only have a few basic colors. The colored lines and circles need to be used for things that can easily get lost. (not attach to that hook thing)

Are you still in need of help?
I have looked at the drawing and all the dimensions do have a reference point, the only thing wrong with the dimensioning is an overlap at the 1.31R dimension I would think this a test and would consider moving that radial dimension so it is readable.
I can run you through the commands.

I create construction lines(their own layer and a vivid purple:wacko: ) where the dimension extensions are. I was able to create this in 2008 in about 2 hours and I'm in the middle of the semester in my first computer drafting(CAD) class in 48 years so can identify with the 'project'. I use the bejeebers out of offsets when creating a drawing.
Oh, the 2R dimension is incorrect in my opinion. I used 1.5 and it looked better/proper.
Ag162 and Englishman seem to lean to a 'teaching' attitude so would reread their suggestions, not to dimish the other advice. They write as if they might be used to answering these beginning(beginner?) questions. Goodness knows you could start a whole new world with what I don't know. Reply/ask if you have a specific, how to or what do I do or why, if you run into problems with this. This is supposed to be the beginners corner me thinks.
Good luck.

The 2R center line measurement is correct and is taken from .88 outside of the .5D circle as shown in drawing; I completed the drawing in 20 mins, 10 mins on mental preparation and 10 mins on physical input.
