Hello, Thanks for the previous reply. If you could have elaborate the if statement with any example then it will be very useful for me. Waiting for your answer. Thanks in advance.
Actually the base point is that if I take any family and I have to use conditional statement formula to that, then what parameter will be use to create that formula?
That's a start. You can use most types of parameters in a conditional statement except for text parameters. Follow the Revit formula link in my signature for the detailed explanations and examples.
