Hello,
I’m a student from South Korea currently developing a conceptual design framework for eVTOL aircraft using SUAVE.

For my project, I’ve installed SUAVE in developer mode and have been experimenting with the eVTOL tutorial and associated videos.
In the tutorial video, I noticed the use of [SUAVE.Input_Output.OpenVSP.write] to export the aircraft geometry parameters—defined in the main script—to an OpenVSP file.

However, when I tried the same approach, I received the following message:
Resetting OpenVSP Model in Memory
VSP import failed

As a result, the geometry file was not generated as shown in the video.

Currently, I'm running the project in a Python 3.8.10 virtual environment within VS Code. I have also installed OpenVSP in this environment.

Has anyone else encountered this issue?
Or is there a specific installation step required to integrate OpenVSP when setting up SUAVE in developer mode?
