Geometric Description Language

Geometric Description Language (GDL) is a specialized computer language used in CAD (Computer-Aided Design) systems to define and record the shapes and structures of objects. It describes objects mathematically through points, lines, curves, and surfaces, allowing precise and flexible modeling. GDL enables engineers and designers to create, modify, and share detailed geometric data electronically, facilitating accurate manufacturing and visualization. Essentially, it's a standardized way for software to understand and manipulate the geometric information of physical parts and assemblies.
