3-D solid design greatly simplifies the standardization and synchronization between design and manufacturing, reduces errors, speeds up delivery, and achieves more reliable results. Working in a 3D solid can identify many manufacturing issues in advance, allowing the designer to detect potential collisions, verify correct shrinkage values, and determine if the parting surface is manufacturable. Through 3d, a complete detailed and consistent model is maintained throughout the design and manufacturing process so that changes from design to manufacturing and assembly can be quickly and reliably combined.

Nobody wants to look at the 2-D model again.  The people in the workshop want to see exactly what they are building, and the customer wants to see exactly what they are getting. Some of the very large, very complex molds we make today have more than 800 parts and weigh more than 40 tons. We may not even be able to handle these types of work in a 2d environment.
