Hi everyone, I am new to Revit and primarily work with inventor and have hit a road block with this parameter equation.
=TAN(15°*PI()/180°)*(Depth-1.500), Depth-1.5 = 11.5 in this case answer should be 3.081 the closest I've gotten throwing darts was = (Depth-1.500)*15°*pi()/180° which is returning 3.011
Any help would be greatly appreciated.
Thanks,

In this case actual depth is 13.500 inches - 1.500 inches = 11.500 inches. The Depth can change the 1.500 dimension and 15 degree angle are constant.
Sorry I don't get it. How can Depth varies and you expect the outcome to be a fixed value? And 13.5-1.5 = 12 btw.
TAN(15°*PI()/180°)
This doesn't make sense. 15d divided by 180d even out the unit. It is no longer an angle to calculate TAN.
The posted equation works with imparts or model states in Inventor. 11.5 would be the base length, 15 degas the angle. However I solved the issue. Parameter B = Depth(any) - 1.500 inches. Parameter Rise = B * tan(15deg)

The above formula makes sense. The original doesn't. Why did you introduce pi()*180d is a mystery.
See link below, an old post from "RevitForum" with possible revit formula's which includes calculations with angles:
