Macro Debug Help

Hi guys, I'm writing a macro to automate some tasks...as all do...and keep having trouble with this part that is designed to (from the model) save out a step file of the part/assembly into a location on my desktop, open the drawing of the part/assembly, then save all pages of the drawing as a pdf in the same location on the desktop.  Some reason I can never seem to get a PDF to generate right... but here it goes.  The issue I'm having is at the first boolean command I'm getting a "Object variable or With block variable not set" error.  Am I using the boolean command wrong?  Is there something better I should be doing?

Debug.Print "Model name is " & swModelName; " - swModelName" & vbCrLf
Debug.Print "Original model location is " & Model.GetPathName & vbCrLf

'Model.SaveAs (NewPath)
Debug.Print "New Save Location is " & NewPath; " - NewPath "

dwgPath = Model.GetPathName ' Get the path of the current part
dwgfPath = (Strings.Left(dwgPath, Strings.Len(dwgPath) - 6)) & "SLDDRW" ' Find the drawing associated with that part

' Open the drawing
