This is a legitimate technique to start concept development, although it has several drawbacks. It may take extra work to move the paper concept designs to the following stage of development. Additionally, it may be more difficult to completely research a variety of design possibilities. What is the justification, though, for switching to digital 2D concept designs?
Compared to manual drawings, CAD has a number of benefits that make it a vital tool in today’s design industry. These benefits are beneficial to modern engineers and product designers in a variety of ways.
A thorough understanding of your notion can be provided by having your idea modeled with CAD because communicating your thoughts clearly is frequently insufficient. Iterative and time-consuming is how manual drawing is traditionally done. There has been a paradigm change from conventional manual drafting to computer-aided design and drafting since the introduction of CAD.
Traditional drafting methods make it simpler to communicate the clarity that may be attained than CAD drawing methods. The creation of manual drawings requires the use of paper, but CAD drawings may be stored and used electronically without the need for paper. By taking over as the main means of expressing design intent, CAD drafting has truly revolutionized the Architectural Engineering Construction sector.
