I'm trying to create a radius along an edge 3,000 mm long. I am being told by Creo that I cannot enter a value lower than 0,30, but I would like to use 0,25. Is it to do with the minimum radius setting being a percentage of the edge length? How do I fix this please?
Solved! Go to Solution.
Thanks Martin. When I go into "Prepare model" I can only specify a new relative value (currently 0.0012). How to I determine absolute, please?
file > Prepare > model properties
Within the model properties window, select change to the accuracy row
Within the accuracy window, use the pull down menu on the left; two choices - absolute or relative. Pull down on right, insert value (0.01mm or .0004 IN is standard automotive practice) select Regenerate Model then close the model properties window
in your config, be sure to add
Thanks Chaps, I'm getting there slowly, but not I'm quite there yet.
I have absolute working as an option. The default value was ~0.3. I have tried to enter in 0.01 as suggested (unless I've misinterpreted?) but the following error occurs:
What is this value actually linked to when relative (a percentage of the maximum edge length in the model?) and what is it driving when absolute, please?
Assuming that my thinking below was on the right lines, I tried your settings first, Martin, and the absolute has worked (although my relative still defaulted to 0.0012).
Many thanks to you and Ron for your help.
As I understand it...
Relative is a tolerance based on a percentage of distance
Absolute is a tolerance of accuracy with no regards to distance applied
Relative accuracy is the ratio of the longest edge to the smallest allowed edge. That's why small details fail on large parts.
Absolute accuracy is the absolute limit on the shortest edge allowed. It is, therefore, units dependent.
It's possible that it's not edge related but feature size related, I don't recall for sure,but the general concept still applies.
