To my knowledge Duplicating an equation as described with the SW table seems not possible to me, but with an Excel-based nomenclature I guess it's feasible.
On the other hand, it is possible to link the equation not with the cells but rather with the columns if it can be useful;)
It's possible to see the example I had made some time ago; To do this, you have to click at the top of the column, then when you have the black arrow, a window will open and there you click on it, then you put your equation there, and there it will be assigned to the column and no longer to a box. Once these are done, you will have to save your new nomenclature.
I confirm what I said in the previous message about:
The nomenclature in Excel format allows you to do the manipulation in question (the trick of sliding via the small +) capture 0 and 01.
The fact of linking the columns to the places of the cells in ka table has a solidworks base. Capture 02
@l.loyal regarding the text format thinks of using the combobox or instead of entering the name of the column which indeed a text (the title of the column) not necessarily the same name of the property;)
