CubePy can be imported directly within the CUBE GUI. Python scripts can be included in Application Editor through what called "CubePy" programs. The default interpreter is the one coming with the CUBE installation, but it is possible to define a different interpreter through the Tools > Options > CubePy window . At the current state of development, it is not possible to set up a virtual environment as part of the project level settings, therefore to use external packages with the default interpreter it is necessary to install them manually through:

“C:\Program Files\Bentley\CUBE7\Python\python.exe” -m pip
