Thanks for the quick replies, I uploaded an image of what I'm after: https://www.tomvandeputte.nl/axostirling.jpg in architectural drawings, the idea of such an axonometry (maybe I'm mistaken with the name) is that one can simply rotate a building plan - which remains the same (the proportions remain the same, it does not distort) in the axonometry. I hope I make myself clear, and someone knows how to fix this!
