No matter what I do, this file refuses to open. I downloaded all the tutorial files for Autodesk Inventor Fusion, and unzipped them to my hard drive. But when I try to open the file the page just flickers a bit, and then nothing. I can get the car file to appear on the grid section of Fusion, but when I click it or try to open it from the open files menu, it does nothing. Can someone please tell me what I am doing wrong? Thank You!
