Note: As of Archicad 25 Update 3, PARAM-O is available to SSA/Forward customers only.
PARAM-O is a node-based environment to create parametric ARCHICAD objects. You can design your objects in a graphical interface, and then PARAM-O saves it as a regular ARCHICAD object in the embedded library.
The PARAM-O scripts are stored as a section of the library part. The created objects will work in every ARCHICAD - even if PARAM-O is not installed.
For details on each node type, see:
