Hi @wim,
Just to make sure … if you type the ‘EditPythonScript’ command from Rhino wip and then select “options…” from the “Tools” menu do you see that directory in the “Module Search Paths” box? I’m asking because you have \6.0\ in your path and instead it could be something like \wip\.
After you check that can you confirm that userinterface.py contains the missing (GetReal, GetString, …) functions?
Thanks,
Alain
