Problem:
You’ve got a clever iLogic configurator assembly (or part) and you are using it to generate new assemblies on demand. But how can you lock down the configured assembly so that the ‘As Built’ state of the file is maintained?
Solution:
Well – this is a big topic. If you are worried about file security your best bet is to get Vault installed and start locking released files properly to prevent edits. However for my loyal readers without the benefit of Vault – it may be beneficial to have the option of ‘stripping’ all the iLogic out of the assembly once generated, thus making edits not quite so simple.
So with that in mind the iLogic code below will delete every iLogic rule in every component in the assembly, including rules in the top level assembly itself. It will however, preserve any rules called ‘Delete All Rules’. This exception means that you can name this rule ‘Delete All Rules’ when you paste it into the top-level assembly, and ensure that it won’t delete itself when it runs, causing a lapse in the space-time continuum.
Note: This rule will still work if you paste into a single part file and run it, but of course make sure you still name the rule ‘Delete All Rules’.
Important:
Cadline won’t take responsibility for accidental loss of iLogic rules as a result of using this code.
Backup ALL part files (not just the top-level assembly) before using.
If you use this code on an Inventor file without backing it up first please don’t come running to me!
Note: Some code appropriated from J.D.Kriek on the Inventor forum here – http://autode.sk/1vkEBzy many thanks.
