How can you safely use InventorViewControl with ApprenticeServer without crashes?

HANDBRAKE is one of the most popular and free video conversion tools.

It is open source, easy to use, and works on Windows and Mac.

Yes, Nishan-it is possible to build an Inventor assembly file (.iam) offline, without launching the Inventor UI, using the ApprenticeServer API.

You can prepare a blank .iam template and use Apprentice to:

1. Open the template
2. Insert existing .ipt files as component occurrences
3. Save the modified .iam

Here’s a simplified VB.NET snippet using Apprentice:

Dim apprenticeApp As New Inventor.ApprenticeServerComponent
Dim asmDoc As ApprenticeServerDocument = apprenticeApp.Open("C:\Templates\BlankAssembly.iam")

Dim partDoc As ApprenticeServerDocument = apprenticeApp.Open("C:\Parts\MyPart.ipt")
Dim asmCompDef As ApprenticeComponentDefinition = asmDoc.ComponentDefinition

' This part is tricky — Apprentice does not expose AddOccurrence directly
' You'd need Inventor API for precise placement and constraints

asmDoc.SaveAs("C:\Assemblies\BuiltOffline.iam", False)

Sheets in Inventor are named using the Sheet.Name property. By default, they follow a simple pattern:

• Sheet1, Sheet2, etc.
• You can rename them manually or programmatically using:

sheet.Name = "Assembly Overview"

You can delete sheets using the Inventor API or iLogic. Here's a VB.NET-style snippet that safely deletes all sheets except the first:

Dim oDoc As DrawingDocument = ThisApplication.ActiveDocument
Dim oSheets As Sheets = oDoc.Sheets

' Delete all sheets except the first one
Do While oSheets.Count > 1
    Dim lastSheet As Sheet = oSheets.Item(oSheets.Count)
    lastSheet.Delete()
Loop

Yes, you can edit the text inside a sketch used by an Emboss feature via the Inventor API — and there’s a clean way to do it programmatically.

Sample VB.NET / VBA Code

Dim oPartDoc As PartDocument = ThisApplication.ActiveDocument
Dim oCompDef As PartComponentDefinition = oPartDoc.ComponentDefinition

For Each oEmboss As EmbossFeature In oCompDef.Features.EmbossFeatures
    Dim oSketch As PlanarSketch = oEmboss.Profile.Parent

    For Each oTextBox As TextBox In oSketch.TextBoxes
        Debug.Print "Original Text: " & oTextBox.Text
        oTextBox.Text = "Updated Text Here"
    Next
Next

This:

• Navigates to each EmbossFeature
• Accesses the sketch used for the emboss profile
• Loops through all TextBox objects in the sketch
• Updates the text content

Yes, you can detect whether dimensions in a drawing were retrieved from the model (IPT file) using the Inventor API. Here's how to do it:

Sample Code: Check if Dimension Was Retrieved

Dim oDrawingDoc As DrawingDocument = ThisApplication.ActiveDocument
Dim oSheet As Sheet = oDrawingDoc.ActiveSheet

For Each oDim As GeneralDimension In oSheet.DrawingDimensions.GeneralDimensions
    If Not oDim.RetrievedFrom Is Nothing Then
        Debug.Print("Dimension '" & oDim.Text.FormattedText & "' was retrieved from model.")
    Else
        Debug.Print("Dimension '" & oDim.Text.FormattedText & "' was manually created.")
    End If
Next

This lets you:

• Identify dimensions linked to the model (IPT)
• Filter out manually created dimensions
• Optionally tag or style them differently
