Product design and development must be absolutely efficient in today's competitive manufacturing scene. Models of computer-aided design (CAD) act as a guide for turning abstract concepts into physical objects. Still, the first ideas may call for changes to fit customer expectations and pragmatic production reality. Optimizing CAD models, checking rapid prototype, guaranteeing product quality, and improving general design efficiency all depend on properly accessing and analyzing comments from many stakeholders. This helps to save costs. This thorough investigation explores the ways to get comments, properly understand them, and apply improvements to maximize CAD models for improved manufacturing results.
