While 2D CAD drafting packages are simple and relatively straightforward, they can be labor intensive for designers of plastic injection mold This is because users must create the required views without the aid of the software package. formerly 2D views are drawn, it becomes unruffled more difficult to track changes by the agency of the multitude of sheets that delineate a complex mold. Errors can then slip between the walls of the process.

Designing the features of a mold while avoiding interferences becomes earnestly easier with 3D CAD methods This type of system also maintains links between mold features
