Hello - please see the attached python - (7.1 KB)

To use the Python script use RunPythonScript, or a macro:

_-RunPythonScript "Full path to py file inside double-quotes"

A plug-in version - Unblock it in Windows and then drag and drop onto Rhino (7 or later)

thank so much

IF i modify the isocurves, does the contour change also?

Hopefully not, using the tool I posted - you tell me if it does!
