PromisE API Save AsDegFile

Hi there,

Could someone describe the parameters of this function? or give an example of its actual use?

Bentley.Electrical.UI.Base.MigrationServiceBase.SaveAsDwgFile(ByVal filePath As String, ByVal drawingDir As String, ByVal strDestPageName As String, ByVal strVersion As String)

I've tried several options as what to place on the paths or names but i can't make it to create the DWG.

thanks!
