Jason,
I think your request is close to impossible to achieve with all but the simplest of drawings. It is all too easy to read what you expect to see and a typo on a drawing, particularly a busy or complex one is very easily read as such. Moreover, who do you choose for the task?
Even the late, great Tubal Cain, in the 3rd Edition of his Workshop reference book, made a fundamental error on a one off drawing of the cone angle for the Myford spindle nose from just such oversight
12 degrees 25 minutes is shown as 2 degrees 25 minutes. Late in the day that might even look right.
Trawling through a minefield of dimensions containing 31/64 and 17/32 with vital numbers missing to read 3/64 and 7/32 instead [just as examples] would be so easy to overlook.
I am more inclined to expect the author to have done that sort of proof reading as thoroughly as possible, perhaps with the help of a friend or knowledgeable acquaintance, than hope someone else entirely remote from the concept is sharp enough to spot such errors. Authors should be traceable from the publishers in any case to answer queries that arise on the work they have had published.
Regards
Brian
