Solidworks macro implementation not working with Python

Question

I've got a macro (see below) that will load in a curve using xyz points from a .txt file into Solidworks. To be clear this gives the desired output.

Dim swApp As Object
Dim Part As Object

Sub main()

Set swApp = Application.SldWorks

Set Part = swApp.ActiveDoc
Dim myModelView As Object
Set myModelView = Part.ActiveView
Part.InsertCurveFile("Generic Filepath\Points.txt")

End Sub

I'm trying to get the same macro to run from Python using this implementation:

import win32com.client

sldw = win32com.client.Dispatch('SldWorks.Application')
sldw.NewDocument("C:\Program Files\SOLIDWORKS Corp\SOLIDWORKS\lang\english\Tutorial\part.prdot", 0, 0, 0)  

Part = sldw.ActiveDoc
Part.InsertCurveFile("Generic Filepath\Points.txt")  

#Cleanup the com reference. 
del sldw

I know I can run Solidworks macros from Python as I have got some tests to work. When I run the macro Python does not output any kind of error message and nor does it generate anything in Solidworks.

Running the Python code line by line in the editor line Part.InsertCurveFile("Generic Filepath\Points.txt") returns False.

With Solidworks open and a part document open the following works:

import win32com.client
import pythoncom
pythoncom.CoInitialize ()

sldw = win32com.client.GetObject (Class='SldWorks.Application')
Part = sldw.ActiveDoc
Part.InsertCurveFileBegin()
Part.InsertCurveFilePoint(0, 0, 0)
Part.InsertCurveFilePoint(0, 1, 1)
Part.InsertCurveFilePoint(1, 1, 1)
Part.InsertCurveFileEnd()

How do I make the Python implementation work?

try to add sldw.NewDocument(r'C:\Program Files\SOLIDWORKS Corp\SOLIDWORKS\lang\english\Tutorial\part.prtdot', 0, 0, 0) after line with Dispatch — Vladyslav Litunovsky

@VladyslavLitunovsky I tried that, I should have mentioned that I had Solidworks open with a new part document open in it. Interestingly running the Python code line by line in the editor, it is fine up till Part = sldw.ActiveDoc but Part.InsertCurveFile("Generic Filepath\Points.txt") returns False. I'll update my question. — Darth Vader

Try Part.InsertCurveFile(r"Generic Filepath\Points.txt") or Part.InsertCurveFile("Generic Filepath/Points.txt") — Vladyslav Litunovsky

Neither of those made a difference. I'm wondering if its a permissions issue with the file? — Darth Vader

I think I've got it to work using Part.InsertCurveFile("Generic Filepath/Points.txt"). It was an issue with the filename. I've got it working now. — Darth Vader

It looks the problem with \ (backslash). Replace it on / or declare string as raw (with and r in front of it) r"Generic Filepath\Points.txt"
