Accuracy Summary

[dgschaefer]

I started on pro/E in ’96 on rev 16, but I worked for an injection mold tooling shop. In the mold package, matching accuracy between the molded part and the mold extracts was crucial, so we always used absolute because relative made it hard to match. So I’ve used absolute accuracy at 0.0001” from the beginning with no issues that I can recall. The issues I’ve had with accuracy have come from using relative rather than absolute.

Hell All,

Great discussion and great feedback and information!

Can you tell what accuracy proE has chosen to use ifwe havespecified "relative accuracy"?

We make electraonic equipment, so our physical boxes are typically the size of a laptop but may be as large as the trunk of a car. We user relative accuracy, so I am assuming ProE uses these very, very tiny components and to determineit's relativeaccuracy. With the more complexity and detail in our design, we are finding that we are bringing our systems totheir kneees. It is a catchh 22 - greater detail, greater accuracy, more regen time, less fluid graphics, etc.

Any insight or experiances/advice you would like to share would be helpful?

Thanks,

Dave
