List and describe three differences between parametric modeling and traditional 2D computer-aided drafting techniques.
a) Parametric modeling allows for easy modification, supports complex geometry, and facilitates design analysis.
b) Traditional 2D drafting lacks precision, is time-consuming, and offers limited design flexibility.
c) Parametric modeling requires specialized training, provides real-time collaboration, and is expensive.
d) Traditional 2D drafting is obsolete, lacks compatibility with modern software, and is inefficient.
