QCAD.org Forum

What I am trying to do is basicaly this:

- create a live link between Sverchok and QCad.

This could be easy to do with a watchdog, that can be activated somehow with a checkbox.

Here is an example of reading a dxf file opened in QCad and creating 3D geometry in Blender.

Next - I will showcase the reverse.

Question:

- on windows 11, it is possible to do with a javascript script to call somehow the revert function with a trigger outside qcad?

If QCAD is running, you can load additional files or run a script by launching it again with the appropriate parameters:

For example, to trigger the revert menu, you can launch:
A more sophisticated solution would involve QFileSystemWatcher.

Thank you!

I will use the simple aproach!

I will come back with feedback if/how I've solved it.

Thank you for the tip! This code does the trick for me in python.
I've realised I don't need a live update.
But I can use a watchdog to do it if I would find it more conveninent.


import subprocess

# Set up the paths
qcad_path = "C:\\Users\.......\\Downloads\\qcad-3.31.2-pro-win64\\qcad-3.31.2-pro-win64\\qcad.exe" # Path to the exe
dxf_file = "model_export.dxf"

# The Revert comamnd
command = [qcad_path, "-exec", "scripts/Pro/File/RevertFile/RevertFile.js"]

# Run the comand
subprocess.run(command)

print("The DXF file has been reset in QCAD.")
