It seems that 51% of concept design work is now done using electronic based systems, including 31% already using 3D data. But, this also means 49% of concept designs still begin as hand-drawn sketches and in engineering notebooks. Although paper based design work is a justifiable method for working on concept designs, the limitations are becoming more pronounced. As technology advances and more companies than ever before work on a global scale, it could be time to make the switch.
