How to save a drawing to pdf using a macro with the current File Name?

Hi,

I want to use a macro for converting a Drawing file (.slddrw) to a PDF rather than using the process of File->SaveAs->.PDF

Following is the coding for the macro which obviously outputs the file as PDF with the name RWT-ANCIL107. How can I change it so it takes the name of the current drawing file.

Thanks for your help

Dim swApp As Object

Dim Part As Object
Dim boolstatus As Boolean
Dim longstatus As Long, longwarnings As Long

Sub main()

Set swApp = _
Application.SldWorks

Set Part = swApp.ActiveDoc
boolstatus = Part.Extension.SelectByID2("Sheet1", "SHEET", 0.08896809136181, 0.2385039130435, 0, False, 0, Nothing, 0)
Part.ClearSelection2 True
longstatus = Part.SaveAs3("C:\Documents and Settings\rbankapur\Desktop\RWT-ANCIL107.PDF", 0, 0)
End Sub
