Hello all,
I found a unique scenario where when traversing the BOMRow of the structured BomView, the ComponentDefinition is "Nothing" (During this line in the code below: Set oCompDef = oRow.ComponentDefinitions.Item(1)).
It only happens to items that are in iAssemblies that are two subassemblies deep. I've attached my file but here is the structured of my Assembly:
- Assembly1.iam
- SubAssembly1.iam
- SubSubAssembly1.iam
- SubSubAssembly2.iam
- SubAssembly1.iam
Assembly1.iam and SubAssembly1.iam are iAssemblies each with a different configurations of it's child assemblies.
The end goal is to export all the items from the highest level assembly, depending on which member is active (Assembly1.iam). Why am I unable to get access to the ComponentDefinition? It works in all other scenarios which makes me believe it has something to do with how Inventor combines the parts in the BOMView, specifially in iAssemblies.
Here is the code I am using, it's the same as ones I've seen floating around these forums. I am running Inventor 2018.1
Public Sub BOMQuery()
' Set a reference to the assembly document.
' This assumes an assembly document is active.
Dim oDoc As AssemblyDocument
Set oDoc = ThisApplication.ActiveDocument
Dim FirstLevelOnly As Boolean
If MsgBox("First level only?", vbYesNo) = vbYes Then
FirstLevelOnly = True
Else
FirstLevelOnly = False
End If
' Set a reference to the BOM
Dim oBOM As BOM
Set oBOM = oDoc.ComponentDefinition.BOM
' Set whether first level only or all levels.
If FirstLevelOnly Then
oBOM.StructuredViewFirstLevelOnly = True
Else
oBOM.StructuredViewFirstLevelOnly = False
End If
' Make sure that the structured view is enabled.
oBOM.StructuredViewEnabled = True
'Set a reference to the "Structured" BOMView
Dim oBOMView As BOMView
Set oBOMView = oBOM.BOMViews.Item("Structured")
Debug.Print "Item"; Tab(15); "Quantity"; Tab(30); "Part Number"; Tab(70); "Description"
Debug.Print "----------------------------------------------------------------------------------"
'Initialize the tab for ItemNumber
Dim ItemTab As Long
ItemTab = -3
Call QueryBOMRowProperties(oBOMView.BOMRows, ItemTab)
End Sub
Private Sub QueryBOMRowProperties(oBOMRows As BOMRowsEnumerator, ItemTab As Long)
ItemTab = ItemTab + 3
' Iterate through the contents of the BOM Rows.
Dim i As Long
For i = 1 To oBOMRows.Count
' Get the current row.
Dim oRow As BOMRow
Set oRow = oBOMRows.Item(i)
'Set a reference to the primary ComponentDefinition of the row
Dim oCompDef As ComponentDefinition
Set oCompDef = oRow.ComponentDefinitions.Item(1)
Dim oPartNumProperty As Property
Dim oDescripProperty As Property
If Typeof oCompDef Is VirtualComponentDefinition Then
'Get the file property that contains the "Part Number"
'The file property is obtained from the virtual component definition
Set oPartNumProperty = oCompDef.PropertySets _
.Item("Design Tracking Properties").Item("Part Number")
'Get the file property that contains the "Description"
Set oDescripProperty = oCompDef.PropertySets _
.Item("Design Tracking Properties").Item("Description")
Debug.Print Tab(ItemTab); oRow.ItemNumber; Tab(17); oRow.ItemQuantity; Tab(30); _
oPartNumProperty.Value; Tab(70); oDescripProperty.Value
Else
'Get the file property that contains the "Part Number"
'The file property is obtained from the parent
'document of the associated ComponentDefinition.
Set oPartNumProperty = oCompDef.Document.PropertySets _
.Item("Design Tracking Properties").Item("Part Number")
'Get the file property that contains the "Description"
Set oDescripProperty = oCompDef.Document.PropertySets _
.Item("Design Tracking Properties").Item("Description")
Debug.Print Tab(ItemTab); oRow.ItemNumber; Tab(17); oRow.ItemQuantity; Tab(30); _
oPartNumProperty.Value; Tab(70); oDescripProperty.Value
'Recursively iterate child rows if present.
If Not oRow.ChildRows Is Nothing Then
Call QueryBOMRowProperties(oRow.ChildRows, ItemTab)
End If
End If
Next
ItemTab = ItemTab - 3
End Sub
Solved! Go to Solution.
