- Get all titleblocks directly with an all elements of type method, an all instances of method, or an all elements of category method.
- Get what sheet they are on by pulling the name or number value from the TB’s parameters.
- Get other data from each TB and build a dictionary where the ordered list of values is the data, and the Key is the sheer number or name.
- Pull all sheets using a all elements of category node.
- Get all sheets numbers or names.
- Get the values from the dictionary for each sheet and set the parameter values accordingly.
