There was a time when product manufacturers had to rely solely on 2D drawings and documentation during the design process. This often resulted in product data becoming inconsistent as it travelled from department to department.
No matter which way you spin it, that’s never going to end well.
For a product to be delivered on time, within budget and built to the highest possible standard, there needs to be a single source of truth in the design.
