In this Question Line video, Jason answers the following question regarding the origin, or zero point, of a part:

How do you find the origin or Zero of a part?

 

In this video, Jason shows how to find the zero, or origin, for a given feature control frame. He explains that the origin (0,0,0) is the intersection of the datum planes that make up the datum reference frame called out in the feature control frame. He walks through an example drawing that utilizes a single datum reference frame, describing how the datum reference frame fully constrains the part. He also notes that more complex parts may utilize multiple datum reference frames, which would result in multiple origin points.
