How to set AttributeSets in Assembly based on AttributeSet of Part?

[roger.fankhauser]

Hello Inventor Community,

I have following situation: 

Assembly1:

•  2 x Part1 --> Has AttributeSet with Name = "ANSYS_NS_COLLECTION"
  • Item1.Name = "S_" ,  2 Faces
  • Item2.Name = "W_",  2 Faces

• 2 x Part2 --> Has AttributeSet with Name = "ANSYS_NS_COLLECTION" 
  • Item1.Name = "S_",  3 Faces 
  • Item2.Name = "W_", 3 Faces

I added the attributes over the Ansys Addin (named selection manager) 

Part 1: 2 faces for "S_" and 2 faces for "W_"

Part 2: 3 faces for "S_" and 3 faces for "W_"

In the Assembly I want to check if there are parts with AttributeSet Name = "ANSYS_NS_COLLECTION".

If so, create new attribute on assembly level with the same faces as in part level but the item name must be renamed to "S_count" respectively "W_count". ("S_1", W_1"). The AttributeSet Name should remain "ANSYS_NS_COLLECTION".

In the end the Assembly should have 8 attributesets:

• Attribute Set Name: "ANSYS_NS_COLLECTION"
  • Item 1 Name: "S_1" , 2 Faces 
  • Item 2 Name: "W_1", 2 Faces
  • Item 3 Name: "S_2", 2 Faces 
  • ...
  • Item 7 Name: "S_7", 3 Faces
  • Item 8 Name: "W_8, 3 Faces

Attached is the sample CAD File of the assembly as described here. 

What I have so far is to get all the Attributes from the parts. But I dont know how to create new one in the Assembly? 

Public Sub AssemblyAttribute()


    'check that the active document is an assembly file
    If ThisApplication.ActiveDocument.DocumentType <> kAssemblyDocumentObject Then
        MsgBox ("Please run this rule from the assembly document file.")
        Exit Sub
    End If
    
    ' Get the active assembly document
    Dim oDoc As AssemblyDocument
    Set oDoc = ThisApplication.ActiveDocument
    Debug.Print "Active Document: " + oDoc.DisplayName

    With oDoc
        For i = 1 To .ComponentDefinition.Occurrences.Count
            Dim oOcc As ComponentOccurrence
            Set oOcc = .ComponentDefinition.Occurrences(i)
            Debug.Print "NS for Part: " + oOcc.Name
            
            Dim oAttMgr As AttributeManager
            Dim oAttsetsEnum As AttributeSetsEnumerator
            Set oAttMgr = oOcc.Definition.Document.AttributeManager
            Set oAttsetsEnum = oAttMgr.FindAttributeSets("ANSYS_NS_COLLECTION")

            Dim oAttSet As AttributeSet
            Dim oAtt As Inventor.Attribute
            
            For Each oAttSet In oAttsetsEnum
                For Each oAtt In oAttSet
                    If InStr(oAtt.Name, "S_") Or InStr(oAtt.Name, "W_") Then
                        Debug.Print oAtt.Name
                    End If
                Next
            Next
        Next
    End With
    
End Sub

Produces following output:

Active Document: Assembly1.iam
NS for Part: Part2:1
W_
W_
W_
S_
S_
S_
NS for Part: Part2:2
W_

Why don't you create iProperties on part level and then write AttributeSet in the assembly ?

to create an attributeSet in an assembly, you need to access it from the occurrence object

A first draw. Suppressed files and virtual components must be ignored.

As far as I know it's not possible to store faces in Iproperties. I need to know the location of the face which is defined in the part document. I had some issues trying this. Becase the face had already an attribute. 

[roger.fankhauser]

Thank you! How can I add the Face? The code will create attributes but whitout the face. 

 The attributes in the part document are set to the face. 

In the assembly it created assembly attributes but not on the faces. What I need is to create the FaceProxy attributes on the same location as in the part document. 

[Ralf_Krieg · Accepted solution]

Hello

On one hand you write you need attributes in the assembly with the count (or sum) of faces of type S_ and W_ in each occurrence. On other hand you write that you need attributes on every face proxy. Or do you mean a mix of both, an attribute on every face proxy with the count or sum of type S_x and W_x for each occurrence as value? If so, we need to modify code a bit.

You can "copy" every face attribute to it's face proxy in assembly space wih code below.

Perfect! Exactly what I needed🙂 

In the meanwhile I tried it by myself but did not get the solution. The error occured when I tried to add the attribute to the attirbute set. Could you explain me what I did wrong?
