Back in my corporate days we would use:
1. A rectangle phantom lined box with a note (flag or delta with an arrow point to box) indicating the requirement (Size, etc.).
2. A phantom line box with a distance dimension and tolerance and a note indicating size
3. For machined parts, Solid Edge (version 14) there is (was?) a macro that could be used to create custom text for machining. Combine with dimensions
4. A note and arrow indicating location:
“ VIBRO-PEEN” or “VIBRO-ETCH” PART NUMNBER XXXX-1, USING .25” LETTERS AT APPROXIMATE LOCATION SHOWN.
