Before the custom properties tab was a Easy to use function, i have spent the last few months developing a PDM/MRP automation system all based on them.
ive only had 2011 installed a couple of hours and im yet to understand why, and how to fix this new mess.
Now custom properties tab as some apply/reset tab. also when you change them, or go to Save the file, it asks
"custom properties has been changed would you like to save"
like as if you want to save a copy of the file with the old old custom properties before you make the changes.
Great... its not like this changes work procedures or makes it any easier for a non-solidworks custom property savy person to understand.
