A few months ago start learning how to make applications with revit api with C and I have been surprised the many applications that can be generated. Although I have stuck with something that was not very complicated in dynamo (With the help of the Data-Shape package) where it gave the facility to the user to enter a value and was saved in a shared parameter. I have reviewed in several forums but no luck. I know it’s a dynamo forum and there is a revit api forum, but they have not been able to respond. I wish they could help me.
