Parameter Calculated by Square Root and Exponential Factor

[alexandre]

I need to calculate the diagonal of an escalator with parameters of a revit family.

With the following equation:

D = Diagonal (mm)

IF = Inferior Length (mm)

SL = Superior Length (mm)

h = Height (mm)

inclination = (degrees - o)

I need to calculate the diagonal of an escalator with parameters of a revit family.

With the following equation:

Diagonal = sqrt((Height^2)+((IF + SL+ (Height/tan(Inclination))^2)))

However, Revit returns that I have an inconsistent unit.

One part of the equation agrees:

(IF + SL+ (Height/tan(Inclination))^2)), but when it is included (Height^2) or sqrt. Revit the inconsistent unit warning message.

I tried to calculate in a separate parameter (Height^2), but the message persists.

Thanks if anyone has a tip.

Sounds like you need a neutralizer.  That is, divide by 1 or multiply by 1.

Your brackets are wrong.  Try this:

sqrt((h ^ 2) + ((IL + SL + (h / tan(Inclination))) ^ 2))
