I'm currently working my 5th year as Manufacturing Design Engineer in a company here in the Philippines.
One of my work here is to provide necessary drawings in 2D and 3D for the purposes of supplier
reference for them to quote, for customer's overview, and for our own reference in manufacturing.
In Manufacturing Drawing, I'm the one who Detailed the parts, its Material to be used and also what are the processed to be done.
For customers drawing, I made it on 3D so that the less technically inclined customers will have the idea or overview what they will buy from us.
