Hello, and thank you to everyone that may reply...
My question is in regards to formulas, variable conditions...
Here's what I'm trying to do...
IF (current value > 0' 0", keep value, set value)
Now...I'm just getting started in conditions, but have been coming from an Autocad environment... Have programmed for over 15 years... LISP, ActiveX, Object DBX...
I don't know if all expressions, conditions, variables have been exposed on some site...or should I just ask for a total count of all allowed expressions, and formulas....
I just want to be able to check the value entered and have it keep the value if greater than 0 (zero), if not then set the value back to the previous value or display a warning.
I'm trying to move away from my old ways of thinking, and move toward enhancing my understanding on how Revit objects, families, have family parameters work....
I welcome all your comments, and ask for direction on family parameters, and formula expressions, conditions, and exposed codes...
Thank you once again.
