Thank you everyone for all the responses. I now agree that a basic dimension is not for use in this situation.
The assembly has a graphite brush and the dimensions in question do not have tolerances. The baseline is part of the carbon that varies when installed. This these dimensions are...
I am looking for any information if there is any on standard balloon shapes. I am unsure if they are just a company standard, or if there is a standard in the mechanical industry?
I would like to know when to use part-list balloons, note reference balloons, and more if there are more.
Also...
Can you use a basic dimension when no GD&T is used? ie I want to use a linear basic dimension on a spring assembly in order to denote the ideal lengths. I personally would not consider this a reference dimension.
Please let me know if that is unclear.

A vs C
B vs B
C vs A
If no what are some standard practices?
In the past my company had its revision start lowest(A) at top and ascend.(Note my companies revision block is...
