Tolerance issue
Hello all, i have been working with Creo 3 for quite some time now, but only on the modelling/surfacing side. Recently i have found myself having to use it for drawing too, & i am discovering all sorts of issues. I am working my way through them as they crop up, figuring things out, but this one has me stumped. Lets say i have a dimension on my drawing, & i edit the properties to change the tolerance style, the size is 100.00mm. I have a tolerance of +0.05/-0.00 applied to the size. The problem occurs when i change the style to limits, to display the size as 100.00-100.05, Creo automatically changes the nominal size to 100.025, forcing a regeneration of the part. I have never seen this behaviour before, i am using the same dtl file i have used for years, this does not happen in Creo/elements pro 5. I really don't like this, rightly or wrongly, we have a way of tolerancing here, & this will cause problems. If i display the dimension as 100.00 +0.05-0.00, my nominal size remains 100.00mm. Pretty sure there will be a config option behind this, & rather than troll through all those, i thought i would ask the question here in the hope that somebody will say "yep", this is the option responsible.
Regards
John
