Given the following information, how can I search (Ctrl+F) the offending elements:
C95(SERVO20-20-10):Connection_3
Not only the parts involved, but their "invalid constraints", being the case
I assume C95 stands for component with either feature number or ID of 95
And Connection_3 would then be a constraint, either of this component in the assembly or - if the component is a subassembly - a constraint inside this subassembly.
In the Search tool, when searching for Simulate elements, you need to set Look for: "Simulation Modeling Object".
Then you can search for the name Connection_3.
