DampingPartStiffness class

The DampingPartStiffness class gives you access to define damping part stiffness cards in PRIMER. More...

The PRIMER JavaScript API provides many class constants, properties and methods. For Arup to be able to extend and enhance the API in the future any constant, property or method names beginning with a lowercase or uppercase letter are reserved.
If you need to add your own properties or methods to one of the existing classes then to avoid any potential future conflict you should ensure that the name begins with either an underscore (_) or a dollar sign ($) or the name is prefixed with your own unique identifier.
For example if company 'ABC' need to add a property called 'example' then to avoid any potential future conflict use one of:

Note that object properties that are parameters are normally returned as the integer or float parameter values as that is virtually always what the user would want. For this function to work the JavaScript interpreter must use the parameter name instead of the value. This can be done by setting the Options.property_parameter_names option to true before calling the function and then resetting it to false afterwards.. This behaviour can also temporarily be switched by using the DampingPartStiffness.ViewParameters() method and 'method chaining' (see the examples below).
