How to Use Dynamo Parameterization to Control Wall Properties
To obtain wall components in Revit, start by using the Revit Selection Select Model Elements node, as discussed in previous articles about retrieving the type names of family components. The next node we will use is similar: Revit Elements Element SetParameterByName. This node has three input ports: element, parameter name, and parameter value, which are necessary for setting parameters.
Parameter values can be controlled using sliders, such as the Number Slider. It is important to ensure that the parameter names match exactly with those in Revit and that the parameters are editable. For example, the area and volume parameters of walls are often grayed out in Revit and cannot be edited. Attempting to set such parameters will result in an error.
