Editing Euclidean geometry (section)

===CAD Systems===
*'''3D Modeling''': In [[Computer-aided design|CAD (computer-aided design)]] systems, Euclidean geometry is fundamental for creating accurate 3D models of mechanical parts. These models are crucial for visualizing and testing designs before [[manufacturing]].

* '''Design and Manufacturing''': Much of [[Computer-aided manufacturing|CAM (computer-aided manufacturing)]] relies on Euclidean geometry. The design geometry in CAD/CAM typically consists of shapes bounded by [[Plane (geometry)|planes]], [[cylinder]]s, [[cone]]s, [[torus|tori]], and other similar Euclidean forms. Today, CAD/CAM is essential in the design of a wide range of products, from [[car]]s and [[airplane]]s to [[ship]]s and [[smartphone]]s.

* '''Evolution of Drafting Practices''': Historically, advanced Euclidean geometry, including theorems like [[Pascal's theorem]] and [[Brianchon's theorem]], was integral to drafting practices. However, with the advent of modern CAD systems, such in-depth knowledge of these theorems is less necessary in contemporary design and manufacturing processes.
