I want to create a hole table for the top view and another one for the bottom view, independent hole table in the same sheet.

Is this possible? I tried but didn't work...

could you please share the model

In fact, you have to create separate tables if the holes are machined from different sides. A hole table will not recognize holes drilled from the other side of the material.

I may be mistaken, my holes tables were on separate sheets of the same drawing (i.e. page 1 & page 2). Again, the first page was one side with one table and the second page was the opposite side and the second table. It two machine set ups, so two pages may work for you.

Good clarification. I didn't try this. It should work. That said, the machinist in me is a little nervous about this idea altogether... very easy way to mess up zeros or misinterpret dimensions.

Thanks!

I don't think this is possible. Creo gives this error message when attempting to create the table:

I think when it says one view, it really means one model or something similar. No matter what I tried, I couldn't get the second table to place. Here are a few things I tried.

Create an origin csys for top surface table and bottom surface table
Place Top and Bottom views independently (not projection)

I'm wondering if the reason you're trying this is because of the way hole tables work in Creo. They really don't work...

The biggest reason why we don't use them is because they only show holes that are created on the same surface as the origin coordinate system. Holes that come in from the bottom surface won't appear in the table. You can redefine the holes on the bottom so that they start on the top and they will show in the table but sometimes this isn't possible or doesn't make sense.

Its possible to create hole tables driven by axes or points so you could create two tables (Creo allows this) and then just delete the rows from each that you don't want to show.
