In today’s construction industry, the most commonly used software is undoubtedly AutoCAD, a 2D drawing tool that designers rely on daily. Within AutoCAD, points, curves, and planes are defined by planar coordinates and parameters such as length or radius. This makes AutoCAD a parametric software, though its functions lean more towards manual drawing.
When it comes to 3D BIM software, Revit stands out as a fundamental modeling tool. Its internal elements—beams, slabs, columns, and various “families”—are controlled by parameters, yet it still primarily relies on manual modeling.
It is important to understand that BIM parameterization requires the use of computer programming languages. This means BIM parametric software not only supports manual modeling and drawing but also allows users to write scripts using programming languages. These scripts can integrate data, graphic information, and geometric algorithms to create and control irregular surface models with complex details and unique shapes. This capability is a key advantage of BIM parametric software.
BIM parameterization technology mainly relies on computer languages and is characterized by multiple functions, a variety of types, and detailed specialization. Widely used BIM parametric software falls into two main categories: those suited for conceptual design and planning analysis, and those designed to assist with construction drawing design and precise control.
For conceptual design support, popular BIM parametric tools include Rhino and its plugins Grasshopper and Paracloud. Maya/MEL and its secondary development plugins operate by converting all factors influencing a building into script parameters, which are then analyzed through logical algorithms to enable computer-aided modeling that supports construction drawings.
BIM parametric software is closely integrated with traditional BIM applications, notably architectural BIM software like Revit and ArchiCAD. Other tools include Pro/E, which is used for integration with post-processing, and CATIA, which is employed in industrial manufacturing. By leveraging these programs, architects can design complex non-linear surfaces and achieve precise positioning and detailed optimization of large-scale nodes within virtual digital models—capabilities that traditional software cannot provide.
