Didn't know about Fusion 360. I've watched Autodesk from version 1 of autocad - the draftspersons took to it easily.
I used sketchup. It took some getting used to how to draw things. Nice drawing paradigm which suited me. Needed to know its limitations. One of those trade-offs between learning how to drive something fully featured vs something I could use rapidly.
When it came to making things the simple 2D components were redrawn by workshops (fibreglass foam and steel laser cut) to produce dxf files that were known to work with their CAM systems. Producing STL (3D printing) is possible but also a bit unreliable and I haven't tried. Perversely STL seems to represent the surface of a solid object as connected triangles which are then sliced to get to a format the printer uses.
Gait F360 is also free for hobbyist and even businesses under $100k a year. Its a good package and the license is yearly but its ongoing and has been for a while. its a solid package and I like it. Im a former drafter and have used microstation, autocad etc and its reasonably good.when I want a printed circuit board, or even a complete circuit, I log on to a website, draw the schematic, convert it to a board layout, press a button for quote and order. Totally confident I get what I intended. As a low volume customer, with laser cutting, machining and 3D printing I have to go through a contorted process, a compromise between file format conversions or redrawing with possible errors and dollars.
Its hard to find a job shop for small orders in Aus.
Had a look at Fusion 360. Thought I'd download before a couple of mobile Gb expires. I'm not a student or educator and that free licence is 3 years. Otherwise 30 days trial. Anything that expires is bad. Yes, I know there are "work arounds".
I have an old copy of Sketchup (pre the last time the business changed hands). No strings. Locked in a time warp - but it works.
