Going from WF4 to Creo 3.0 soon. I'd also like to know if there are replacements for these 2 obsoleted config options. Anyone have an answer?
tol_mode was obsoleted in Creo 1 by the introduction of detailing options for solids, File > Prepare > Model Properties > Detail Options, 'default_tolerance_mode'.
sketcher_dec_places I have less direct knowledge of, it appears that it was obsoleted in WF5 and employs 'default_dec_places' instead. I could be mistaken, so test before relying on that.
