Create your FreeCAD Python script (e.g., my_script.py) containing the FreeCAD
API calls as if it were a macro. Use Pythons subprocess module to execute the
freecadcmd (or FreeCAD.exe --console or similar, depending on OS) executable,
passing your script as an argument. Example Script: python import subprocess
import os
# Define the path to the freecadcmd executable or AppImage
# Adjust this path based on your installation
# Example Linux: FC_PATH = '/usr/bin/freecadcmd'
# Example Windows: FC_PATH = 'C:\\Program Files\\FreeCAD X.YY\\bin\\freecadcmd.exe'
# Example AppImage: FC_PATH = '~/Downloads/FreeCAD_*.AppImage'
FC_PATH = 'freecadcmd' # Try this if the executable is in your system PATH
script_to_run = 'my_script.py' # Your automation script
try:
# Run FreeCAD in no-GUI/console mode, executing the script
result = subprocess.run([FC_PATH, script_to_run], capture_output=True, text=True, check=True)
print("Script ran successfully.")
print("Output:\n", result.stdout)
except FileNotFoundError:
print(f"Error: FreeCAD executable not found at '{FC_PATH}'. Check your path.")
except subprocess.CalledProcessError as e:
print("Error running FreeCAD command.")
print("STDOUT:", e.stdout)
print("STDERR:", e.stderr)
