We could use some advice regarding what other companies, particularly those in consumer electronics, are using for accuracy values in Creo. We've been using relative accuracy as a default, and of course that comes with a lot of issues. We're exploring values for absolute accuracy, and we thought to reach out to the community to hear your experiences. We've heard that Motorola, for example, uses 0.003 mm. Can anyone share what you're using and successes and failures from your approach? Thanks in advance.

In Reply to John Moody:
Discussion of absolute accuracy should include the typical part size, no?
Yes and no, it has to do both with the size of the part, and the size of the smallest features you want to include with them. These features create small vertices and curves which affect part stability. We make sheet metal parts and use about 0.0025" (the smallest size typically available given our dimensions).
