Algorithmic modeling: the futurism in CAD
Algorithmic Modeling: a futuristic direction in CAD and industrial design
The most genuine and vivid example of parametric design is Antonio Gaudí’s complex structural forms on Colònia Güell Chapel. Gaudí created an inverted model of the building using string weighted down with birdshot. Strings settled into a shape and, when inverted, stood in compression.
What is Parametric (algorithmic) Modeling?
Parametric modeling, also called parametric solid or algorithmic modeling, and parametric design explains a dimension’s ability to change the model geometry after modifying the dimension value. For non-tech geeks, this sounds quite difficult. So let’s try one more time. Parametric Modeling is the process of creating a digital model that is based on pre-programmed algorithms (parameters). The elements of models are automatically changed instead of being manually manipulated.
The history of Parametric Modeling is related to the term “parametric” originating in maths that was first used in 1988 when Parametric Technology Corporation released the first successful Parametric Modeling software. The first examples of parametric modeling were introduced in the ’80s with 2D and 3D models.
Moretti discussed parametric architecture and parametric design a few decades earlier, presenting the idea of a parametric design on a stadium model and explaining the dependency of parameters and their forms that changed the viewing angles.
As a computer-aided design (CAD) software tool, algorithmic modeling is a great time saver that eliminates the necessity of redrawing the same design any time one of the dimensions changes. Before parametric modeling, when modifying any of the elements of 3D solid, the designer had to change the other two parts. With parametric modeling, the adjustments are made automatically. Typically, a designer defines parametric rules that create relationships between different elements within the design. Parametric/algorithmic modeling focuses on those relationships between features changing them upon request.
Advantages of Parametric/algorithmic Modeling
The option to build flexible designs
Multiple ways to view 3D solid models, including rendering
Quick design turnaround
Better visualization and approach
Better integration with downstream applications and manufacturing processes to decrease the development time
Reduced engineering time
The capability to reuse existing design data for creating new designs
A valuable tool for creating
a model to be used in non-engineering functions
A clearer view of the future product
Automated drawing production provided by 3D systems
Whether used in architecture or any other industry, parametric design draws inspiration from nature and its shapes.
Mostly, designers do parametric modeling in-demand, and the design initially has an owner. It is evident that models are private property hidden and shared with stakeholders. So is there no chance to get ready-made parametric models? BeeGraphy features the only source of ready-to-use parametric models available online for editing and downloading.
