@asdasd201@lemmygrad.ml The sad reality is that you will likely have no choice but to use AutoCAD since that's what your instructor wants you to use. Even if you are able to use something free/open, there is always a chance that something in the file will render incorrectly when loaded into AutoCAD. The best thing (I think) you could do is do the assignment in both #AutoCAD, and #CAD software of your choosing be that #FreeCAD, #QCAD, #blender, #LibreCAD, or something else with which I'm unfamiliar. After class, speak with your instructor and teach them that these things can be done using #FOSS solutions as well, could be they don't even know. Worst that happens is you'll have taught yourself how to do the same thing in different software. Everything that was taught (that I can recall) in the #drafting classes I took 30 years ago can be done in any of the softwares I mentioned, but I'm sure things are a bit different these days. It's quite irresponsible of educational institutions to push students into specific software, versus teaching concepts which can be translated across multiple. Teaching students only about expensive licenced software (regardless of providing free student licences) over the concepts used to accomplish the task, promotes ignorance over education, and encourages software pirating.
