Finding where a dimsion (d###) is used in a design sketch

[Fusion9B89M]

Have to redefine a saved parameter in order to change the Units.  However, I know there are no uses of that variable any longer - I deleted the one use, but I'm getting an error "cannot delete ... used in d###."

Unfortunately, as "d" numbers are global (to design), and not sketch specific, I cannot find it - I know the original dimension using the parameter is d123, which I'd changed to reference the new, correctly defined Unit, variable.  There are only 2 dimension used in that sketch (d123 & d124), but ... I tried deleting the dimension referenced (d123 - unresolving the sketch), but I still get the error. 

Checking teh other two sketches, none of theirs are in the d12* range at all.

How do I find the "d" location where that variable is used so I can reference the new parameter, and delete the invalid one?

Thank you

Open the Parameter Dialog box, place the model variable "d" number you are looking for in the Search box, it will find it in the parameter table and give you the entity it is related to.  If you use Capture Design History, it will highlight the entity in the Timeline.
