So i realized autodesk 123D cannot open stl files recently which is a huge limitation for me since I am a novice and use thingiverse so much to modify objects. So i started using the online version of 123D on the autodesk website and it let me open/import stl files. then all of a sudden i went to open a file and all my files in every different format includin stl were that light faded color you cant click on. so on the downloaded design app i cannot browse my computer for stl and on the online design site i cannot browse and open anything. help please? i do love the software though. thanks!
