Hi Maulik
What are you tying to do with Excel and how do you want to control it.
While I don't know how to directly control creo with excel, you can use excel to create txt files, which creo can then use to control paramters and setting in family tables.
example of a txt file that updates the family table.
You can also edit the family table with excel by clicking this button
this allows you to edit the family table via an excel spread sheet. showwn below
There may be more options, but this is what we are doing now.
would love to know more about how to use excel within creo myself, as it is one of my favorite tools.
