Hi -
One approach can be to use a custom tool..
Either executed by a button , but maybe the most user friendly method,
will be to let a custom tool be triggered automatic when a drawing part is saved in NX..
1.Defined a weight or mass attribute in your drawing template..
2.Link this attribute to the desired Cell in Titleblock..
3.The EstabPartProps1 function will calculate entire assembly weight in one shot..
4.Transfer the value into the attribute...
You need access to an advanced Assembly licens - then you can use this UFwrapped function..EstabPartProps or EstabPartProps1, if you are dealing with Vb.Net…
