**Get Built In Parameter**  
This node will query up a built in parameter by its name. If a list of names is supplied to ParameterNames input then it will return a nested list containing parameter values for each supplied element.

**Rename Files**  
This node will rename files in a specified directory based on a unique identifier. Identifier is a string that if contained in a destination file name will trigger this definition to rename it to a new name from a corresponding list supplied into New Names input.

This node also requires a Boolean toggle supplied to RunIt in order for it to execute.

**String From List**  
This node will take an input of a list and concatenate each item from a list to create one string. It will use a user specified separator between each item on a list. Use Nested Lists to build complex strings for, let’s say, custom file names.

**Print PDF**  
This node will initiate a print procedure in Revit based on a few inputs.

- Views – This is a list of views (Sheets are views in Revit API) that will be printed.
- Print Range – Use Print Range node to get available options for this setting. I have only tested it with “Select” as input so far so choose carefully. :-)
- Combined File – is a Boolean input that when set to True will combine all printed files into a single PDF.
- Printer Name – Available printer names can be obtained from Local Printers Names node. So far I have only tested it with Adobe PDF.
- Print Settings – These are settings that will be applied to each sheet. Use Print Settings node to query up currently available user defined Print Settings.
- File Path – This is a File Path input that should specify a destination and file name ending with .pdf extension. This is a file name that will be applied to a file when Combined File settings is set to True, while if that settings is set to False and individual PDFs are plotted a default name will be used (ProjectFileName-User-Sheet-SheetNumber-SheetName.pdf)
- RunIt – its a Boolean input that when set to True will execute this node. Keep in mind that printing can be a time consuming operation hence I suggest to set this input to True only in strategically timed moments.

**Print Settings**  
This node will query up all user defined Print Settings currently available in the project.

**Local Printer Names**  
This node will query up all locally installed (excludes network) printers and will return their names in a list. This node is useful when defining inputs for the Print PDF node.

**Print Range**  
This node will query up the three available settings for Printing Range.

**Get Views from View Set**  
This node will take an input of a View Set name (string) and return a list of Views/Sheets that are contained in that set.

**View Sets**  
This node will query up all user created View Sets currently in the project. It will return just the name of the set as a String.

**Clear List**  
This node will clear all Null values from a list or nested list.

**Mass Addition**  
This node will perform a Mass Addition on a list or nested list.
