There are lots of good (and some great) tech editors out there. Even I have been known to do some tech editing from time to time (although it is not my best skill). Therefore I am comfortable saying that I am detailed oriented and generally write clear sand concise instructions. Even so, I know that I would be a fool not to hire a tech editor, here are some things a good tech editor will do for you:
- Check your numbers to make sure the math actually works.
- Check numbers against schematic measurements to ensure that what you say will happen will happen.
- Make sure that all abbreviations are defined and any that aren't used are eliminated.
- Ensure that phrases and terms are used consistently, not only within the pattern, but also between patterns if they are all part of the same pattern line.
- Check that the pattern format is consistent and all the key elements are included
- Correct punctuation.
- If you are lucky, also do some copy editing on the descriptive pieces.
