Parameter of Revit API – 50: Parameter Converter – Parameter to SharedParamete
We talked about programmatically converting parameters from one to another manually before. Now let’s see how Parameter Converter of RevitAddinWizard can assist us to hit the target with just a few mouse clicks. The Parameter Converter can be found from either Revit Addin Coder sub-menu under the Tools or from Revit Addin Coder toolbar.When the menu item or the tool button is clicked, the Parameter Converter window will show up:

If the Parameter (to SharedParameter) Converter is selected from the check list box and a class is chosen from the combo box, a Parameter to SharedParameter Converter will be created and added into the class automatically. The entire converter code and necessary namespaces and class declarations have been appended below:<div align="left" style="color: rgb(105, 105, 105); font-family: 'Microsoft Yahei', Simsun; "></div><div align="left" style="color: rgb(105, 105, 105); font-family: 'Microsoft Yahei', Simsun; ">

As mentioned, Parameter Converter of RevitAddinCodercan create all these code automatically in a second.
