Thank you for your comments pmarc.
The difficulty is that wherever I have worked people have different personal preferences on how things are shown on drawings whether they work to a standard or not. In an ideal world I would have enough time to read/reference every standard and do everything...
I am currently working on a pretty basic label drawing which contains differing hole sizes for push buttons and mounting screws. The difficulty has arisen in the dimensioning of the drawing (although this is a formality as the label makers will transfer straight from CAD)
I have been pulled up...
