Syntax
public static bool IsValidThickness( double thickness )
Public Shared Function IsValidThickness ( thickness As Double ) As Boolean
public: static bool IsValidThickness( double thickness )
static member IsValidThickness : thickness : float -> bool
Parameters
- thickness Double
- The input value.
Return Value
BooleanTrue if the input value is valid for thickness; false otherwise.

- The value is greater than or equal to the minimum thickness allowed in Revit for these types of geometric constructs.
- The value is less than or equal to the maximum length/distance allowed by Revit for elements.
