How can I control tolerances on a particular hole if it's part of a group? Daniel Lyon November 20, 2012 17:48 I have a part with thousands of holes in it. I need a few holes to have a tighter tolerance than the others but they are all the same physical size in the model. What should I do? Have more questions?

If the holes are grouped together you can right click on the group and select Edit Feature List. This will allow you to remove holes from that group and separately control the machining strategy for those holes. You can change the setting in the parameters option for the feature or by changing the operation settings.
