Suppress Part Pattern Element from iLogic Rule within Assembly

[KarlH_]

Hey all,

I have written a couple of iLogic rules that execute within a Part, that can suppress various elements within a parts Pattern Feature.

Unsuppress all Pattern Elements;

Dim oPattern As RectangularPatternFeature 
oPattern = ThisDoc.Document.ComponentDefinition.Features.RectangularPatternFeatures.Item("Rectangular Pattern1")

Dim oElement As FeaturePatternElement
For Each oElement In oPattern.PatternElements
    If oElement.Index > 1 Then
        oElement.Suppressed = False
    End If
Next 
ThisDoc.Document.Update

Suppress the last element;

Dim oPattern As RectangularPatternFeature 
oPattern = ThisDoc.Document.ComponentDefinition.Features.RectangularPatternFeatures.Item("Rectangular Pattern1")
 
Dim oElement As FeaturePatternElement
 
oElement = oPattern.PatternElements.Item(oPattern.PatternElements.Count)
oElement.Suppressed = True

ThisDoc.Document.update

Suppress the desired element;

Dim oPattern As RectangularPatternFeature 
oPattern = ThisDoc.Document.ComponentDefinition.Features.RectangularPatternFeatures.Item("Rectangular Pattern1")

Dim oElement As FeaturePatternElement
Dim number As Integer = 5

For Each oElement In oPattern.PatternElements
    If oElement.Index = number Then
        oElement.Suppressed = True
    End If
Next 
ThisDoc.Document.Update

And suppress the middle element(s) - pending odd or even qty.

Dim oPattern As RectangularPatternFeature 
oPattern = ThisDoc.Document.ComponentDefinition.Features.RectangularPatternFeatures.Item("Rectangular Pattern1")

Dim oElement As FeaturePatternElement

If oPattern.PatternElements.Count Mod 2 = 0 Then 'if the count is even
    For Each oElement In oPattern.PatternElements
        If oElement.Index = (oPattern.PatternElements.Count / 2) Or oElement.Index = (oPattern.PatternElements.Count / 2) + 1 Then
            oElement.Suppressed = True
        End If
    Next 
Else 'if the count is odd
    For Each oElement In oPattern.PatternElements
        If oElement.Index = (oPattern.PatternElements.Count + 1) / 2 Then
            oElement.Suppressed = True
        End If
    Next 
End If
ThisDoc.Document.Update

These all work well from a testing point of view, but perhaps they could be refactored or simplified (and by all means, please feel free to comment/update).

But I'm now needing a hand in having these rules executing from a parent assembly of that part, that contains the parts Pattern Feature - I just can't seem to get the syntax right.

If worst comes to worst, I guess I can leave these rules nested within the Part, and call the parts iLogic rules via the assemblies main iLogic sub, but would prefer if I could alter these rules so that they're run from the parent assembly, keeping the part free from iLogic rules.

Appreciate any help, thanks!

Nothing to mention on your code, seems fine.

To go through parts in an assembly, please look here:

https://modthemachine.typepad.com/my_weblog/2009/03/accessing-assembly-components.html

Maybe you need to activate the document before you change pattern.

You can do that with:

Dim occdoc As PartDocument = oOcc.Definition.document

occdoc.activate

When you do that, you need to change thisdoc.document to occdoc in your code

If you know the exact name of the component:

Dim oDoc As AssemblyDocument = ThisDoc.Document
Dim oOccs As Inventor.ComponentOccurrences = oDoc.ComponentDefinition.Occurrences
Dim oPrtDoc As PartDocument = oOccs.ItemByName("bla").Definition.Document

And just a reminder that this type of thing breaks if you are ‘Load Express’ on your assembly. It works fine but if the your assembly file is express loaded, the definition is not yet fully loaded, and thus not editable.

someone else had a similar issue their code in a large assembly, which should have otherwise worked.
