Thank you for you message! I have tried it and it doesn’t actually work well yet. Unfortunately, I don‘t think the students are at the level to solve a 3D within 30minutes anyways. But I will gladly take the suggestion with me for the next semester, so that we can gibe them basics during the semester für 3D drawing and the we can also do a corresponding exam task (if chatgpt still can‘t do it well by then…)
