Small text (part number) on a part won't regen.

[melias-2]

When trying to show a part number (.12" high) on a part that is 60" long, the text will not regen. If the text is made much larger Creo has no problem. Is there a setting that can be changed that would allow this to show? We do MBD with Creo 3.0, M100

This is an accuracy issue. Go to FILE - PREPARE - MODEL PROPERTIES - ACCURACY

If you have relative accuracy, it's based on a length vs. width ratio. Long part causes problems with small details.

If you have absolute accuracy, it's a explicit value is specified.

I suspect you probably have relative accuracy and you just need to make the number smaller.

Be careful, save before you change it. If you have merges, all your accuracies of all your parts must match.

Changing accuracy can cause unexpected failures.

What Stephen Williams‌ said.  You may need to enable absolute accuracy.  It also doesn't hurt to provide a default value for absolute accuracy.

default_abs_accuracy  0.0001

enable_absolute_accuracy yes

+1! 

PTC really should automate accuracy when it comes to using thin features on large parts.

Maybe a prompt that says something like, "Yes, make my %^&$# feature" button.
