Nodes in Orchid for Dynamo are continuously being developed, therefore is the most secure site to use the Orchid dictionary to get information about the nodes in the package, or follow the Orchid distribution at GitHub. News are being published at the Orchid blog.
Nodes are generally arranged in two GUI assemblies, which means that the Orchid package can be used both in the “sandbox” version (nodes that are not dependent of Revit.dll), and in the “full” version where all nodes are available. Both GUI assemblies get the methods from the commands assembly.
In the commands assembly is all methods located. These methods (commands) can be used in code blocks (design script) like the dynamo commands.
Inside Dynamo are nodes arranged into different headings: Core, Elements, FamilyDocument, Applications, and about. Currently hold Orchid for Dynamo +150 nodes!
