Hi, Following for the previous issue, I made sure that time that pywin32 and virtual env are active.

And that's the picture inside the folder

And that's the error.

Yup I'm getting the same issue. Just trying to test out a few different ways to hit the solid works api through python

Use this code :

  import sys
  import time
  import asyncio
  import pythoncom
  import win32com.client
  
  # Solidworks Version (write the year):
  SWV = 2023
  # API Version
  SWAV = SWV - 1992
  # Elapsed time
  elapsed = 0
  
  async def main():
      # Attempt to connect to SolidWorks
      try:
          sw = win32com.client.GetActiveObject("SldWorks.Application")
      except:
          print("Failed to connect. Launching a new instance.")
          sw = win32com.client.Dispatch("SldWorks.Application")
          sw.Visible = True
  
      if not sw:
          print("Failed to connect or launch SolidWorks")
          return
  
      print(f"Solidworks API Version: {SWAV}", "\n", f"Solidworks Version: {SWV}")
  
      Model = sw.ActiveDoc
  
      if Model is None:
          print("No active document found. Creating a new document...")
          # Create a new part document (you can change the document type)
          partTemplate = "C:\\ProgramData\\SOLIDWORKS\\SOLIDWORKS " + str(SWV) + "\\templates\\Part.prtdot"
          Model = sw.NewDocument(partTemplate, 0, 0, 0) # You can adjust the last three parameters as needed
  
  
      ARG_NULL = win32com.client.VARIANT(pythoncom.VT_DISPATCH, None)
      ck = Model.Extension.SelectByID2("Front", "PLANE", 0, 0, 0, False, 0, ARG_NULL, 0)
      Model.SketchManager.InsertSketch(True)
      Model.ClearSelection2(True)
  
      mySketchText = Model.InsertSketchText(
          0, 0, 0, "Hello Python World!", 0, 0, 0, 100, 100
      )
      myFeature = Model.FeatureManager.FeatureExtrusion2(
          True,
          False,
          False,
          0,
          0,
          0.001,
          0.001,
          False,
          False,
          False,
          False,
          0,
          0,
          False,
          False,
          False,
          False,
          True,
          True,
          True,
          0,
          0,
          False,
      )
  
      Model.SelectionManager.EnableContourSelection = False
      Model.ClearSelection2(True)
      s = time.perf_counter()
      elapsed = time.perf_counter() - s
      print(f"{__file__} executed in {elapsed:0.2f} seconds until while-loop")
      time.sleep(2)
      while True:
          Model.ViewRotateplusy()
          time.sleep(0.1)
  
  # If running as a script, execute the main function
  try:
      if __name__ == "__main__":
          asyncio.run(main())
  except KeyboardInterrupt:
      sys.exit()

If Solidworks is not open it open it If there is no open part open it create a new part Then it write Hello Python

If you are not using Solidworks 2023 change the year at the beginning of the code
