Hi all,
in Pro/Mechanism you have to adjust the parameter called "characteristic length" to improve the absolute tolerance (the other parameter is the relative tolerance).
The manual says:
"The characteristic length is the sum of all lengths of the parts divided by the number of parts. The length (or size) of a part is the length of the diagonal of the bounding box that completely contains the part."
But this default value is taken following the rule in automatic?
In the 1st picture attached (prima), 10 is the value that appear always, with any part/assembly.
In the 2nd picture (dopo), I've pushed the button "Restore default", and the number changes every time.
I think, in the second case, ProE applies the rule.
Is it correct?
At the end, I wonder if the value of the rule, the default value (if is true what I think), is always the best value.
Regards
