If you are more comfortable using PowerShell and have an Inventor API workflow that you want to quickly test, you can just combine both!
To help demonstrate this, below is a Inventor API sample in PowerShell that exports a drawing file as PDF.
Once you have your Windows PowerShell Integrated Scripting Environment (ISE) up, the first line of code would be to add the Inventor reference DLL as below:
Add-Type -Path ("C:\WINDOWS\Microsoft.Net\assembly\GAC_MSIL\Autodesk.Inventor.Interop\v4.0_25.0.0.0__d84147f8b4276564\Autodesk.Inventor.Interop.dll")
The next step would be to create an instance of Inventor (or get an existing instance if it is already open). To do so, you can add the below lines:
try
{
$m_inventorApp = [Runtime.Interopservices.Marshal]::GetActiveObject('Inventor.Application')
$m_quitInventor = $false
echo 'Getting existing instance...'
}
catch
{
echo 'Creating new instance...'
$inventorAppType = [System.Type]::GetTypeFromProgID("Inventor.Application");
$m_inventorApp = [System.Activator]::CreateInstance($inventorAppType)
$m_quitInventor = $true
}
Now, we open our input drawing document with the “Open as Visible” flag set to False, and use this document object as input to the PublishPdf function.
$document = $m_inventorApp.Documents.Open("C:\TEMP\Hairdryer.idw", $false)
PublishPdf($document)
Now, in our PublishPdf function we add the below lines:
function PublishPdf {
param ($doc)
$PDFAddIn = $m_inventorApp.ApplicationAddIns.ItemById("{0AC6FD96-2F4D-42CE-8BE0-8AEA580399E4}")
$oContext = $m_inventorApp.TransientObjects.CreateTranslationContext()
$oContext.Type = [Inventor.IOMechanismEnum]::kFileBrowseIOMechanism
$oOptions = $m_inventorApp.TransientObjects.CreateNameValueMap()
$oDataMedium = $m_inventorApp.TransientObjects.CreateDataMedium()
If ($PDFAddIn.HasSaveCopyAsOptions($doc, $oContext, $oOptions))
{
$oOptions.Value("All_Color_AS_Black") = 0
}
$oDataMedium.FileName = "c:\temp\test.pdf"
$PDFAddIn.SaveCopyAs($doc, $oContext, $oOptions, $oDataMedium)
}
And finally, close the created Inventor instance:
if ($m_inventorApp -ne $null -and $m_quitInventor -eq $true)
{
$m_inventorApp.Quit()
echo 'Quitting Inventor...'
}
In the above example, while I have hard-coded the input file path, you can also choose to pass this as an input in a command line argument.
