Do Brackets mean no tolerance
Do Brackets mean no tolerance
(OP)
Can someone point me to a reference for the following:
(.xxx) means no tolerance
This is on a drawing and I referred to the block for tolerances.
I believe I am correct referring to the block but I can't find a reference that by putting a dimension into brackets or () this means no tolerances.
Thanks for any help.

I have seen:

(.2)
Thinking primary and secondary.
It should be:
.123
[.2]
(numbers are examples only)
The () is for reserved for reference dims.

It's good to know the background. If you are going to be more involved with mechanical drafting, I recommend either a workshop or a JC class that covers ASME Y14.5M-1994. Best of luck!
