Autocad user here trying to get to grips with Inventor..
My problem is when creating dowels in my models they show up the same as normal drilled holes in the hole chart.
I know I can create a symbol to drop over them (have done this for now) but its the holechart that I really need help with. We make parts with many different hole types and trying to sort dowel holes from drill holes is very time consuming and most importantly leaves room for error which can be very costly in our business (machine tool design & manufacture).
Are your dowel holes the same size as the drilled holes? Only if they're the same nominal size as other holes will they roll up together. Can you post a sample drawing that illustrates the problem? I won't suggest that there isn't a lot of room for improvement in Inventor hole charts, but your problem might still be solvable.
