I've been struggling building some design tables for a 150# RF flange.  It's more of a learning test than anything with using design tables.  I've been watching videos and reading on the tutorials, but they typically work around pretty simple parts, where a dimensionally correct flange with holes, etc. is a little more difficult to tie all the dimension data to the design table.  I'm probably doing things wrong, so please let me know!  I've been able to build formulas that will apply the right amount of holes with the correct clocking based on the "ND1" value,

On a cut or extrusion, since there's no "dimension" available, how do I assign the dimension a name?  d2@boss-extrude1 I think needs to be changed to my "RFLEN" so I can tie it to the design table, but I can't figure out how to rename it.  I can't rename it in the Equation manager, it simply won't let me ENTER out after changing it.

Like I was saying, this is my first try doing something a bit more complicated than a box.  Those are pretty easy to do this way

Any help would be GREATLY appreciated!  We have tons of schedulable data for our industry, and this would be a very good way to build the geometry, so I need to learn these!!!
