The attached document describes the case, which basically means that part annotations were using dimensions from a separate sketch (created as a separate feature in the model tree), and that makes it impossible to hide that sketch on the drawing without the also the geometric tolerances made as annotation also gets to be hidden (The annotation geometric tolerance uses a size dimension from the sketch).
Creo 2 M130 is used.
At the part the sketch feature can easily be hidden and the geometric annotation tolerance still shown, it is only at the drawing the issue appears (Hide/Unhide and all kinds of layers have been tested.)
There is another PTC support case about a similar thing from May 2015, also in Creo 2. The two suggested workarounds are really NO GOD for me, and really no options for what I try to achieve.
See attached document. (Unfortunately no part and drawing can be shared)
