Got it, let's walk through exactly how to run your SolidWorks VBA macro straight from Python—no need to manually open SolidWorks or run the macro inside the app. Here's a step-by-step solution with two solid options:

First up, prerequisites you'll need:

• Install the pywin32 library (to handle COM interactions with SolidWorks):

  pip install pywin32
  

• Ensure SolidWorks is installed on your machine, and API automation is enabled (this is on by default for most installs; if not, check Tools > Options > System Options > General > Enable SolidWorks API in SolidWorks).

Option 1: Call Your Saved VBA Macro File #

First, save your existing VBA code as a .swp file (e.g., CreatePartMacro.swp) in a directory you can easily reference. Then use Python to launch SolidWorks (if it's not running) and execute the macro:

import win32com.client
import os

def run_solidworks_macro(macro_path):
    # Connect to SolidWorks, or launch it if it's not already running
    sw_app = win32com.client.Dispatch("SldWorks.Application")
    # Set to False to run SolidWorks in the background (no visible window)
    sw_app.Visible = True
    
    # Verify the macro file exists
    if not os.path.exists(macro_path):
        raise FileNotFoundError(f"Macro file not found at: {macro_path}")
    
    # Execute the macro: returns 0 = success, 1 = error, 2 = cancelled
    error_code = sw_app.ExecuteMacro2(macro_path, "", "Main", 0, 0)
    
    if error_code == 0:
        print("Macro executed successfully!")
    else:
        print(f"Macro failed with error code: {error_code}")

# Replace this with your actual macro file path
macro_file = r"C:\Your\Path\To\CreatePartMacro.swp"
run_solidworks_macro(macro_file)

Option 2: Translate VBA Logic Directly to Python #

Instead of relying on a separate macro file, you can rewrite your VBA code directly in Python using the SolidWorks COM API. This keeps everything in one script and avoids needing to manage a separate .swp file:

import win32com.client
from win32com.client import constants as sw_const

def create_solidworks_part():
    # Connect to SolidWorks instance
    sw_app = win32com.client.Dispatch("SldWorks.Application")
    sw_app.Visible = True
    
    # Grab the default part template path
    default_template = sw_app.GetUserPreferenceStringValue(sw_const.swUserPreferenceStringValue_e.swDefaultTemplatePart)
    
    # Create a new part document
    sw_doc = sw_app.NewDocument(default_template, 0, 0, 0)
    
    # Select the Front Plane to sketch on
    bool_status = sw_doc.Extension.SelectByID2("Front", "PLANE", 0, 0, 0, False, 0, None, sw_const.swSelectOption_e.swSelectOptionDefault)
    
    # Start the sketch
    sw_sketch_manager = sw_doc.SketchManager
    sw_sketch_manager.InsertSketch(True)
    
    # Draw your outline lines (matches your VBA code)
    sw_sketch_manager.CreateLine(0, 0, 0, 0, 1, 0)
    sw_sketch_manager.CreateLine(0, 1, 0, 2, 1, 0)
    sw_sketch_manager.CreateLine(2, 1, 0, 2, 2, 0)
    sw_sketch_manager.CreateLine(2, 2, 0, 4, 2, 0)
    sw_sketch_manager.CreateLine(4, 2, 0, 4, 1, 0)
    sw_sketch_manager.CreateLine(4, 1, 0, 6, 1, 0)
    sw_sketch_manager.CreateLine(6, 1, 0, 6, 0, 0)
    sw_sketch_manager.CreateLine(0, 0, 0, 6, 0, 0)
    
    # Clear sketch selection
    sw_doc.ClearSelection2(True)
    
    # Switch to isometric view (use "*Trimétrica" if you're on a Spanish-language SolidWorks install)
    sw_doc.ShowNamedView2("*Isometric", 8)
    sw_doc.ViewZoomtofit2()
    
    # Select the bottom line for the revolve feature (coordinates from your original VBA)
    bool_status = sw_doc.Extension.SelectByID2("Line8", "SKETCHSEGMENT", 2.27939213179474, 0.424565217882254, 0.640103542052883, False, 16, None, 0)
    
    # Create the revolve feature
    feature_revolve = sw_doc.FeatureManager.FeatureRevolve2(
        True, True, False, False, False, False,
        0, 0, 6.2831853071796, 0, False, False,
        0.01, 0.01, 0, 0, 0, True, True, True
    )
    
    # Clean up selection settings
    sw_doc.SelectionManager.EnableContourSelection = False
    sw_doc.SetPickMode()
    sw_doc.ClearSelection2(True)
    
    print("Part created successfully!")

# Run the part creation function
create_solidworks_part()

Quick Notes: #

• If you don't need to see SolidWorks run, set sw_app.Visible = False to run it in the background.
• The coordinate values in the SelectByID2 call are copied from your original VBA. If the sketch doesn't select the correct line, you might need to adjust these or use a more robust selection method (like selecting by sketch segment index instead of coordinates).
• If the default template path isn't working, you can hardcode it (e.g., r"C:\ProgramData\SolidWorks\SOLIDWORKS 2024\templates\Part.prtdot").
