NEW PART TEMPLATE _rel vs. _abs

[P40WARHAWK1943]

I am starting a tutorial, the piston, practice session...I installed Creo 7, the tutorial must have been performed in an earlier version.  It starts with a new template, says to use "mmns_part_solid"...you have 2 choices in Creo 7.   mmns_part_solid_abs or mmns_part_solid_rel   Which do I use?  What is the difference between the 2 extensions?

don't know if you are still having trouble but

_abs is short for absolute accuracy

and

_rel is short for relative  accuracy

hear is a link to more in depth information of the differences: https://support.ptc.com/help/creo/creo_pma/r7.0/usascii/index.html#page/whats_new_pma/part-absolute_accuracy_default.html
