NX dimensioning w/ Excel Macro

[AlMireault]

Hi there,

I've dug around looking for an answer to this for a while now and haven't found much.
I have an excel file controlled with a macro (essentially a list of dimensions that are parametrized to each other in VBA) and I want to link that to an NX model (I'm running 8.5). I'm aware that the expressions dialog can be used to create an excel interface for modifying variables ect. but unsure of how to link variables to an existing excel file, moreover one with macro-controlled cells.

thanks for the help

While in the expression system, go to the bottom of the dialog and select the 'functions' icon [f(x)] and when the dialog opens, go to 'Choose a Category' and select the 'spreadsheet' item. Here you will find pre-defined functions for reading the values of cells in an external spreadsheet. Now if you make a change to the external spreadsheet, NX does not automatically detect that and update the part file(s). What you need to do is after the part file is open, whether you're in the Expression dialog or not, you'll need to go to...

Tools -> Update -> Update for External Change

...so as to force an update of the NX model by reading in any changes from the spreadsheet.
