Form Builder is the RealityHub module; you can create custom user interfaces by drag & drop Form fields and components without writing a single line of code. Operators then can 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 FORMBUILDER button on the top-right corner.
