I've used the regular Fusion program and to me it feels like sketchup merged with CAD, you can do some easy push pull sort of designing, but I don't think it has proper sheetmetal support.
The page says so itself, it can be really useful for designer and sculpting project, CNC milling, Blow molds and 3D printing come to mind. But if you are looking for sheet metal fabrication or complex assemblies Fusion360 is not the way to go I think, it is the same as Sketchup in that regard, nice to flesh out ideas but not meant to replace CAD programs like Inventor and Solidworks.
