Help with understanding Threads charts

Hello all,
Hope someone can give some tips and advice with understanding threads charts (bottle threads) and applying them to solid works I cant figure out how to determine the thread profile and pitch from the numbers that are given to me and how to use the "t" dimension?.
further more how should I approach making a mating closure? hope someone has an answer. all the tutorials Iv found dont really show how to use the numbers they only show how the helix is made and the part, but not in depth information.
thanks a lot from advance,
osher,
