ILogic help needed!

Anonymous — Tue, 04 Sep 2012 18:42:40 GMT

Is it possible to have iLogic rule create parts lists out of View Representations?

iLogic set BOM via LOD

Curtis_W — Tue, 04 Sep 2012 20:55:15 GMT

Hi Infoseeker,

If you are use the iLogic function IsActive to suppress component instances, their BOM structure is set to Reference. Therefore the suppressed occurrence, and only that occurrence will be removed from the BOM.

So IsActive not only suppresses the occurrence it also set's it's BOM structure as if you'd right clicked on it and selected BOM Structure > Reference. Recall that this is different that setting the BOM structure in the BOM editor or via the Document Settings, those 2 methods set it per file, rather than per assembly occurrence.

With this in mind here is an example rule. In this rule you select an item (on screen or in the browser, and it will be toggled on/off, and removed or added to the BOM. This is just a quick example to demonstrate the concept.

But to speak to the original request: I suspect you could use this idea to look at each occurrence in an assembly and check it's visibility setting (per the current Design View Representation) and then toggle the BOM structure for that occurrence to Reference if the occurrence is not visible.

I'm short on time, so I can't have a look at this anytime soon, but I thought I'd throw this out in case someone else wants to give it a shot.

I hope this helps.
Best of luck to you in all of your Inventor pursuits,
Curtis

I think it would be much more user friendly if we toggled the bom structure directly instead of using isactive. This way we needn't deal with any LOD headaches.

You can use these snippets to control the bom structure at the assembly level:

Component.InventorComponent("occurence").BOMStructure = BOMStructureEnum.kDefaultBOMStructure
Component.InventorComponent("occurence").BOMStructure = BOMStructureEnum.kReferenceBOMStructure

You could then use a loop to cycle through each occurence checking it's visibility setting per Curtis's suggestion and set it's bom structure accordingly.

Hi mrattray,

I think you're spot on. And here's a snippet I had on hand, to iterate though the component occurrences of the assembly in case it helps someone.

I hope this helps.

Hi Inventor users,

Here's the code snippets above combined into a rule that sets the BOM structure to Reference if the component is not visible.

I hope this helps.

Awesome! Thanks.

This rule needs to be added to the .idw or .iam?

Re: ILogic help needed!

Anonymous — Thu, 06 Sep 2012 21:37:10 GMT

I guess assembly.

Re: ILogic help needed!

Does not work for me, maybe because I also use in my parts list substitute and grouping option... Or I am just missing something.

Re: ILogic help needed!

mrattray — Fri, 07 Sep 2012 14:48:41 GMT

How does it not work? Is there an error message? Did you put it in the assembly?(it has no business being in the idw) Does it do something unexpected? We need more information than "it doesn't work" if we're going to be of any help to you. Can you post the files here?

Re: ILogic help needed!

Anonymous — Fri, 07 Sep 2012 16:36:45 GMT

Yes, I figured out it has no business to be in .idw file, as you can see in my previous post.

The rule has been added to the main assembly file, the one with View Reps that are used for parts lists generation.

I wrote it does not work, with no detailed description, because it just does not work: makes no difference if the rule is there or if is not. No warnings, pop ups, no nothing. No changes to Parts Lists display: total number of the parts is shown if only one out of few is visible in the view.

Does it work for you?

Anyone had a chance to test it?

Re: ILogic help needed!

Anonymous — Thu, 13 Sep 2012 19:18:30 GMT

The code posted by Curtis, works as he descibed. I tested it in a simple assembly

changing a component to be not visible changes the BOM structure to Reference and vice versa

Are you sure the rule is being fired?

Re: ILogic help needed!

When I open standard template, the rule seems to work partially; it sets parts to reference parts but then BOM does not change when I turn visibility on and off.

The other thing is that my QTY comes from iproperty, that is connected to user parameters of a part, not actual number of parts in assembly. Then iproperty numbers are substituted for QTY.

On the picture you can see that I have 3 parts out of 6 visible, BOM shows only 1, the rest is set to reference.

I am using Inventor 2012 with 64 bit Windows 7.

I have the view representation assembly open.

Created the rule, cut and pasted the code.

I am getting the following Errors:

Rule Compile Errors in View_Rep_BOM, in 11-647-12.iam

Error on Line 13 : Method arguments must be enclosed in parentheses.

Error on Line 17 : Method arguments must be enclosed in parentheses.

I have tried putting brackets in, but cannot make it happy. Any help would be much appreciated.

Sometimes copy/paste from this board scews up code. Nobody knows why. Copy your rule and paste into a txt file, post it, and I'll correct it.

Re: ILogic help needed!

mrattray — Wed, 24 Oct 2012 18:57:16 GMT

If you're still workin on this, can you post your data set?

Thanks.

Re: iLogic set BOM via Visibility

mrattray — Wed, 24 Oct 2012 19:09:58 GMT

The code looks fine to me. Is that the entire contents of the rule, or do you have another section that you didn't include? You can try this copy, it's just reformated a little.

If that is the whole rule and the new copy doesn't work then can you post up the data set for me to investigate?

Re: iLogic set BOM via Visibility

Thanks Mike (not Matt)

That was the whole rule.

I don't see that you sent any copy for me.

I am not sure what you require when you ask for the data set.
