Build 2019.33020, Win 10.
It seems when I query a Par class for min/max on a built-in parameter, it always reports 0 and 1. But if I use t-script, as reported by Rob in a post 4 yrs ago, I can get a more reasonable min/max range for a built in parameter. Also, when I tried to do the drag-n-drop method to add custom parameters, the custom param builder also was able to get the correct range.
Can we please promote these values to the Python classes?
