Hey,I saved a volume measurement (shown in model tree) and then I created a paramter using a relation. I want to add a unit to the parameter but it is locked. So how do I add the units to locked parameters?How do I change the decimal value in this drawing title block. I want to show 0.73mm^3 or maybe 0.7mm^3

If you’ve used a relation to assign a value to a parameter, as you’ve observed, it locks the parameter. You can’t change the units of locked parameters. What you can do is comment out the relations you used to set the parameter in question, regenerate, and that should unlock the parameter. You should then be able to set the units for that parameter. Once you’ve set things, uncomment the relations and everything should be okay.

For question 2: add [.1] to the end. The number controls the decimal places in the note

Oh, yeah, also if you want to show mm³ and not mm^3 or something like that, I open up a Word document, insert the ³ character, then copy and paste that into my table, text string, etc. It looks much nicer.
