Flipping component pattern in assemblies with iLogic

Anonymous — Mon, 01 May 2017 18:19:59 GMT

I have an assembly with a component pattern that I want to flip the direction with iLogic (or other rule type) by reading a multivalue parameter which reads either "LEFT" or "RIGHT". Can this be done?

Hello and welcome to the community.

Is the pattern you are changing a rectangular pattern? and if so is it just the the column direction you want to change?

Dim oDoc As AssemblyDocument
oDoc = ThisApplication.ActiveDocument

Dim oAsmCompDef As AssemblyComponentDefinition
oAsmCompDef = oDoc.ComponentDefinition

Dim oOccPat As OccurrencePattern
oOccPat = oAsmCompDef.OccurrencePatterns.Item(1)

If parameter = "LEFT" Then

oOccPat.ColumnEntityNaturalDirection = False

Else

oOccPat.ColumnEntityNaturalDirection = True

End If

If you have more than one pattern, you may want to define the pattern by its name rather than item number. In that instance you would use:

oOccPat = oAsmCompDef.OccurrencePatterns.Item("Component Pattern Name")

(This must be posted exactly at the same moment as someone else)

in 2015 i could not use a multivalue parameter, so i used a True/False paramer, this may be altered if needed.

Sub FlipPattern()

Dim oIamDoc As AssemblyDocument
Set oIamDoc = ThisApplication.ActiveDocument

Dim oIamDocDef As AssemblyComponentDefinition
oIamDocDef = oIamDoc.ComponentDefinition

Dim oRecPattern As RectangularOccurrencePattern
oRecPattern = oIamDocDef.OccurrencePatterns("Component Pattern 1:1")  'Change as needed

Dim oUserParamDirection As UserParameter
oUserParamDirection = oIamDocDef.Parameters.UserParameters.Item("Direction")

If oUserParamDirection.Value = "True" Then 'Change as needed
    oRecPattern.ColumnEntityNaturalDirection = True
Else
    oRecPattern.ColumnEntityNaturalDirection = False
End If

End Sub

This worked beautifully...thank you

I received an error using this one, but I probably overlooked or mistakenly edited the code improperly to fit my situation. Since the code posted above worked, I didn't chase down the error. I still want to thank you for your help though...

Set oIamDoc = ThisApplication.ActiveDocument

Removing the word Set from this line would probably fix the error.

I'm having trouble with this I have a circular pattern that is not working for me.

SyntaxEditor Code Snippet

Dim oDoc As AssemblyDocument
oDoc = ThisApplication.ActiveDocument

Dim oAsmCompDef As AssemblyComponentDefinition
oAsmCompDef = oDoc.ComponentDefinition

Dim oOccPat As OccurrencePattern
oOccPat = oAsmCompDef.OccurrencePatterns.Item("NubSupportPattern")

If OrientationNumeric = 1 Then
oOccPat.ColumnEntityNaturalDirection = False
Else
oOccPat.ColumnEntityNaturalDirection = True
End If

ERROR MESSAGE:

Error in rule: Orientation, in document: Tray Stack, Top_HC3.iam

The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))

I am trying to do flip a circular pattern does that make a difference?

Not able to test it myself, but I think if you change ColumnEntityNaturalDirection to AxisEntityNaturalDirection it will work.

I found that via the API help:

Perfect that worked exactly as intended thank you!

This worked for one assembly but I have a circular pattern nested within a linear pattern in another assembly and its not working correctly. its giving me this message below:

Error Message:

Error in rule: Orientation, in document: Tray Stack, Bottom_HC3.iam

The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))

More Info

I have attached a screenshot of the model tree structure. The "rotational pattern" is the one I want to switch within the "Linear Pattern"

Here is the code:

SyntaxEditor Code Snippet

trigger = OrientationNumeric

Dim oDoc = ThisDoc.Document

Dim oDef As AssemblyComponentDefinition
oDef = oDoc.ComponentDefinition

Dim oPattern As CircularOccurrencePattern
oPattern = oDef.OccurrencePatterns.Item("Rotational Pattern")

If OrientationNumeric = 0 Then
	oPattern.AxisEntityNaturalDirection = False 
Else
	oPattern.AxisEntityNaturalDirection = True 
End If

I am working on something similar, except I would like to reverse the direction of a feature pattern within a part. How do I define the features within the part?
