I use Inkscape and Fusion. Mainly Fusion as I feel my time is better spent there for the long run. Never know where this hobby will take me and I don’t really do artwork. With that said, knowing how to use the basics of Inkscape has definately come in handy countless times for me. You are just going to have to start somewhere and it likely doesn’t really matter where. You might decide that solidworks for ex. is what fits you best, or maybe not. Won’t know without trying. I tried Fusion, Solidworks, Sheetcam, and Inkscape. I now just lay my parts out in Fushion and then they are set. However, if I was doing a lot of one off parts, I just cut the same parts over and over again, where I needed to nest on a regular basis, i’d use sheetcam more. Fusion now has nesting but I havn’te experimented with it. Watching youtube videos and messing around in Fusion has been how i’ve learned. I set out with an idea and would start playing around with it. To start, for awhile, I would end up scraping the project before I started to get the hang of doing what I want Fusion to do for me. Has taken a lot of patience and time but I feel I’m better overall for all of it. Good luck. The rabbit hole is deep.
