Number of array elements = Length / Step.Area of a Circle = pi () * Radius ^ 2.

Length = Height + Width + sqrt (Height * Width).

If the parameter name begins with a capital letter, for example “Width”, then it should be entered in the formulas starting with a capital letter. Parameter names in formulas are case sensitive.

Exponentiation: ^ (Example: 3 ^ 2 is 3 squared)Īll of the following functions have a standard notation: function (value)įor example: sin (Angle) is the sine of the Angle parameter.

The following operators and functions are used in formulas: Revit formulas support standard arithmetic and trigonometric functions.

My friend Chris Alby from measuresurve圓65.co.uk is here to explain all about Revit Formulas!

These Revit formulas range from the simple to very complex! If you’re looking for info on what Formulas are available to you and how to use them, you have come to the right place. If you are building Revit Families, you have probably come across the need to add formulas.

Revit Formulas are powerful ways to drive and control parametric content in a model.
