An example would be "The first field is the number (i.e. A001, A013, etc.) in accordance with..."
The actual details of the sentence do not matter, it is the parentheses that is being referenced in my question.

One of the uses of brackets is re-formulating or rephrasing for clarification; that would be obvious here, so the ie or i.e. is unnecessary. The etc is necessary and clear, though an ellipsis would probably be more normal if there are no other dot-usages. –  Edwin Ashworth Jan 18 '13 at 16:37
No, that's fine, because i.e. and etc. do not overlap. However, make sure you don't confuse i.e. with e.g., as in your example (sorry, I have to say it), because e.g. and etc. do overlap. In your example, I think you use i.e. where you mean e.g., in which case it is redundant. As it stands, your i.e. is simply out of place in that example. –  Cerberus Jan 18 '13 at 16:37
Thank you!! I appreciate your input. –  Sarah Jan 18 '13 at 16:49
Also, keep in mind that it's "etc.". With exactly one period. Not zero, not three. I have edited your question accordingly. –  RegDwigнt Jan 18 '13 at 17:14
The point to the parenthesis is to imply "i.e." without actually having to write it. I always delete it unless the parenthetical remark is a clarifying & simplifying paraphrase of something difficult to understand but necessary because it's the standard jargon. –  user21497 Jan 19 '13 at 0:54

*"The first field is the number (i.e. A001, A013, etc.) in accordance with..."

As you are aware, parentheses and "i.e.," serve the same purpose in this context. As such it would be incorrect to use both together.

"The first field is the number, i.e., A001, A013, etc., in accordance with..."
"The first field is the number (A001, A013, etc.) in accordance with..."
