What causes the “Permission Denied” error when using FileSaveAs in Inventor or Apprentice?

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.

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 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

No, Apprentice Server cannot export Inventor part files (*.ipt) to formats like SAT, IGES, or STEP.

Recommended Steps

1. Ensure All Changes Are Saved

   
   ' After updating properties
   oDoc.Save()
   

2. Force Update of Drawing Views

   
   oDrawingDocument.Update()
   

3. Use Inventor's Built-in DWF Export

   
   oDrawingDocument.SaveAs("C:\Path\To\File.dwf", True)
   

4. Verify Property Source in Title Block
   • Open the title block definition.
   • Check if the field is pulling from <Current Drawing> or <Primary Model>.
   • If it's <Primary Model>, ensure the model file is updated and saved.
