Is there some instruction set or Venn diagram that shows all of the places, relationships controls etc for units, decimal places, truncating zeros etc for Solidworks? 

Seems like there are plethora of different places and different hierarchy in which one effects another. You can change units in the model and it changes it in the drawing or you change in the drawing and that over writes whats in the model. That works for dimensions but not tables and so on and so on. 

Maybe I should put this in the TTL  and suggest that all units, fonts, etc be arranged in a single command center or something. 

Anyway knowing that doesn't exist is there some way to hash this all out, is it shown, listed etc somewhere?

Thank you?
