The value that is inputted into the shared parameter field before it is made into an assembly is not carried over. The parameter field is carried over, but it is empty. So part of the problem is fixed with assigning the shared parameter to the assemblies category. So a step in the right direction!
Where you have the Set Parameter node, needs to be Get Parameter, so I can use the pulled values to set the assembly names and sheet numbers. Right now I have it pulling the values before it creates the assemblies, but I can’t run the script if there are existing assemblies.
