Unpattern & Make Independent

[MH_Clark]

I am using Creo Parametric Release 9.0 and Datecode9.0.3.0

I am trying to unpattern a patterned group and make all the features independent of each other but I can only find "make independent under the model, operations, ATB menu which doesn't seem to work. Can you please help.
I have had a look at the rules for patterning groups in the fo;;owing website but it doesn't seem to help much.

Also had a look at CS131620 - see website below but it doesn't seem to apply to release 9.0

This in an enhancement. 

 Workaround: make a group and pattern the group. Then unpattern is available. This workaround does not work for Geometry Pattern.

See https://www.ptc.com/en/support/article/CS59045

Once you unpattern how do you make the features independent of each other such that you can change their size individually?

Ok I have had more of a look at the Article - CS59045 and found it works with holes but not extruded cuts - see attached part files in the winrar compressed file

After Unpattern and Ungroup the instances can be edited individually using Edit Definition. This works for all instances except the 1st parent instance. I don't see any difference between hole features and extrude cuts.

I think the problem is in my sketch - Confirmed
If the sketch is corrupt when you modify the dimension then creo reverts back to the original dimensions because it can't solve the sketch.
This is quite confusing when you first look at it when unpatterning because it looks like it hasn't broken the dependancy which is true because it never gets to that point - hence why I couldn't understand why it wasn't working.
