As most job shops experience. you get pre drawn parts from many different cad packages. Sometimes they come in with weird origins.
Parts that come from stl data is the worst especially if your client got there stl from a scanner that never bothered to alinge the data before sending.
also as there is no support currently for routing purposes and nesting 3D parts. There is a need for a box to be abled to be toggled on to the part when imported. This will aid in getting the part alinged.
I did put this idea forward before but it did not get enough votes so i thought i would explain it better this time with some screen shoots of what I intended.
So the next photo is of a part I had drawn in polyworks. It originates from a stl file and then was rendered.
So I had to draw a box around this stock to find out where the center of the extremes are.
This is so you can find the center piont as you can see in this slide.
You can the use this piont for many differnt things.
