Have you tried working through the tutorials on Autodesk ' s website ? My guess is that you ' re struggling with something conceptually if you ' ve been going at it for a week and aren ' t beginning to grasp it . Best advice for complete noobs is to start thinking about everything as a 2 D sketch . Everything starts with a sketch . That sketch can pulled and stretched extruded to create a 3 D object . Then you can sketch on that 3 D object and extrude off it , extrude cut into , and so on . Not everything starts with a sketch , but to really understand the concept of programs like Fusion your thought process should almost always begin with how do I start to make this thing by starting with a sketch ? . I hope that helps . Either way you need to push yourself through some tutorials any CADmodeling program requires effort to learn .
