What is the full form of PARAM


What is PARAM-O?

Create Archicad parametric library objects with PARAM-O without writing a single line of GDL code. This easy-to-use tool for creating GDL objects takes advantage of node-based editing - the result is a fully Archicad compatible parametric library object.


  • Fully node-based parametric creation
  • Live preview of the final object as it is being created.
  • Save the result as an Archicad parametric library object.
  • Several basic shapes available (such as block, sphere, cylinder, etc.).
  • Define pen and surface attributes for each shape created.
  • Math and trigonometric operations.
  • Form boolean operations.
  • Transformations of shapes.


Installation instructions

  • Download the appropriate apx file from the download list.
