hey dear,
Abhinav this side, I have many years of experience in 3d cad, and 2d design, plastic injection tools and die Mould design.
I have been working in this field for many years.
3D modelers are usually tasked with replicating real-life objects in software such as AutoCAD, and NX. This usually involves a thorough measurement process. However, a draftsman may carry out these measurements and generate a blueprint from which the 3D modeler can work.
