For most of my working life, we had a tolerance block on our drawing template defining default tolerances, unless specified otherwise. There were separate areas for fabrications and machining. The tolerances depended on the magnitude of the dimension within several defined ranges. Bigger dimension --> Bigger tolerance. We were all happy, and comfortable with this system.
Now, we're converting to model based drawings made in Inventor. Someone has saddled us with a sheet tolerance block in which the default tolerances depend on the number of decimal places in the dimension. So, now we have to code all our nonspecific tolerances into the dimension format. Everyone I work with hates this and thinks it's stupid. Where does this shit come from? Are others doing this? Can anyone offer a good reason for doing this?
