FileDialog.OptionValues Property
Parent Object: FileDialogDescription
Read-only property that returns the settings the user specified in the options dialog when a file type known to Inventor was selected. This includes the standard Inventor types (.ipt, .iam, .idw, etc.) and also any files types supported by any translator add-ins. In the case where it’s an unknown type (i.e. .txt, .xml), or if no options were specified this property will return Nothing.
The NameValueMap that’s returned can be used directly as the NameValueMap for the corresponding translator add-in.
