Hello & Thank you in advance.
I'm working on a drawing in ACAD 2009 and it's a circular plate. My origin is the center and there are exact same dimensions in each quad (sections). My questions is, is there a proper way to dimension this with out adding too many dimensions? I have attached the drawing which I started to dimension. I'm sure I'm sure I'm not giving enough info, so please ask.
If the original ACAD drawing is needed let me know.

If all the dimensions should match (unlike some of those shown), then it should be acceptable to dimension everything in one quadrant or, better, to dimension different features - especially different types of features - in different quadrants to improve legibility.
The abbreviation "Typ." added to each dimension would be normal (it could be added to a dimensional style) or you could add a note "All dimensions are typical".
I would strongly recommend placing centre marks for the holes.

Hello JohnB,
Thank you very much. I had thought of using only a quad for the dimensions. By any chance do you have a drawing or site where I can look at a sample? I also need some more clarification on below, sorry not too Cad savoy. If you can provide a sample drawing for reference.

I have updated the drawing since last post. Please review when you have time. Thanks a million

I can't really add much (though I would definitely pull the 50° dimension outward so that it doesn't look like 45° + 50°).
Your questions are not really about CAD so much as about technical drawing; check your national (and international) standards.
For example - The dimension and leader lines are the same weight (thickness) as the geometry in the pdf copy. Not so in the original, I hope.
What makes the 0.905 thickness a reference?
The elevation at the bottom looks like first angle projection but the elevation on the right appears to be third angle projection.
Keep trying, keep asking.
Good luck.

Hello John,
Thank you much. Will look into dimensioning and take your advice and some items on the drawing. Have a GREAT DAY.
