I am trying to use 3D Annotation in SolidWorks for the first time. It seems pretty easy, but I have run into a stumbling block. I have a large bore that is shown as a datum. If I were making a draiwng, I would take a section and show the bore diamter and list it as Datum B, Can I do thie in 3D Annotation? IF so, can someone give me a step by step?
