Transformations in Computer Aided Design (CAD) involve the matrix representation of points, lines, and planes, as well as various geometric transformations in both 2D and 3D. These transformations include translation, scaling, rotation, and reflection, all of which are crucial for precise geometric modeling and simulation. Understanding the mathematics behind these transformations allows for effective design, analysis, and visualization in engineering applications.
