Issue:
You have a number of standard Virtual parts that
you find yourself adding over and over. You'd like to have the ability to add
them based on a predefined list.
Solution:
Here is an example iLogic rule that will read a *.txt
file and present the contents to the user in an input box list. The user is
then asked to enter a quantity for the virtual part, and then the virtual part occurrences
are added to the assembly. If one or more occurrences of the virtual part exist
in the assembly, the iLogic rule deletes them and just adds back the total
number needed.
