How can I use iLogic with Excel to drive iProperties in an Autodesk Inventor IDW drawing?

The "+/-" toggle in the Edit Parts List dialog controls the expansion or collapse of structured BOM rows, especially in hierarchical assemblies. Unfortunately, this UI element isn’t directly exposed via the Inventor API or VBA as a toggle method.

However, there are workarounds depending on what you're trying to achieve:

Control Structured View via PartsListRow.ChildRows

You can simulate expansion/collapse by hiding or showing child rows programmatically. Here's a VBA snippet that toggles visibility:

Dim oDrawDoc As DrawingDocument
Set oDrawDoc = ThisApplication.ActiveDocument

Dim oPartsList As PartsList
Set oPartsList = oDrawDoc.ActiveSheet.PartsLists.Item(1)

Dim oRow As PartsListRow
For Each oRow In oPartsList.PartsListRows
    If oRow.ChildRows.Count > 0 Then
        ' Toggle visibility of child rows
        Dim oChildRow As PartsListRow
        For Each oChildRow In oRow.ChildRows
            oChildRow.Visible = Not oChildRow.Visible
        Next
    End If
Next

This doesn’t affect the "+/-" icon directly, but it mimics the behavior by collapsing or expanding rows.

Use HealthStatus to Detect Failure

Every feature in Inventor has a HealthStatus property. You can use this to check if a feature is up-to-date, suppressed, or has failed.

Example (VBA-style pseudocode):

Dim oFeature As PartFeature
Set oFeature = oPartDoc.ComponentDefinition.Features.Item("MyExtrude")

If oFeature.HealthStatus <> kUpToDateHealth And oFeature.HealthStatus <> kSuppressedHealth Then
    oFeature.Suppressed = True
End If

In Autodesk Inventor, text justification in custom tables is a bit limited and unfortunately, you cannot programmatically justify the title text of a custom table using the API.

Yes, it is possible to reposition elevation view labels (or any drawing view labels) in Inventor using the API, either by default through styles or programmatically via code.

Set "Active Component ISO View on Save" via Code

You can use the SetThumbnailSaveOption method to programmatically set the thumbnail behavior:

VBA Example

Sub SetThumbnailToIsoView()
    Dim oDoc As Document
    Set oDoc = ThisApplication.ActiveDocument

    ' Set the thumbnail save option to ISO view
    oDoc.SetThumbnailSaveOption ThumbnailSaveOptionEnum.kActiveComponentIsoViewOnSave

    ' Save the document to apply the change
    oDoc.Save
End Sub

Batch Processing

1. Use FileSystemObject or Dir to loop through .ipt or .iam files.
2. Open each file with ThisApplication.Documents.Open(...).
3. Apply SetThumbnailSaveOption.
4. Save and close.
