Welcome to Part 1 of a 3 part Blog on iLogic View Representations!
Question: Can you use iLogic to automatically create and update view reps based on a particular Part Number (or section of a Part Number) you specify?
Answer: Why yes, yes you can.
Part 1 – Creating the View Reps Automatically
I’ve pasted 2 iLogic rules below. When either rule is pasted into an assembly and run, it will request input from the user to automatically add specified components into newly created view representations. Why 2 rules instead of 1? Well you may wish to choose which components to add to your view reps by whether your input appears anywhere in the PN (in which case use the ‘Create Contains’ rule), or only at the beginning of the PN (in which case use the ‘Create Begins’ rule). Otherwise the rules are identical.
Here’s what the ‘Create Contains’ rule will do when it is run (in sequence);
1) Return the view to ‘home’ view.
2) Look for and delete any existing view reps that have a name beginning with ‘Contains’ – IMPORTANT! (delete this part of the code if you want to keep them).
3) Request input string for first view rep.
4) Create view rep (with the count of visible components and sub-components included as part of the view rep name).
5) Fit view to screen so new view rep can be viewed.
6) Ask user if they want to add another rep.
7) Return to 3) if the answer is yes.
As always – a video is better than a thousand words
In part 2 of this blog I’ll provide the code required to automatically update the view reps you have created – stick around. Enjoy!
