Form Builder is the RealityHub module; you can create custom user interfaces by dragging & dropping Form fields and components without writing a single line of code. Operators can then use these custom user interfaces (Form Templates) to control graphics workflow and data.
Form Builder also contains advanced components to ingest and transform external data and feed your graphic templates.
To access the Form Builder panel:
Go to Main Menu > Windows > Nodegraph/Actions
Click the Form Builder button on the top-right corner.
