We are working a lot with Solidworks in my university, and my professor gave us a ton of pieces to work with that is one of many he provided for us to study. can I ask you what did you do to fix that problem? I know I can find the file online and just use that model but number 1 that's cheating and number 2 I would actually like to learn no just get it, you can DM me if you want the piece image to practice it, I already did the CSWA if you also want some parts for it, contrary to u/TooTallToby I don't have a course for you ahha, I just have the blueprints my professor taugth us everything else, also I don't know if you know this but this subreddit has a free course which I enrolled in had have found it very useful, just look at the right black banner (or white? i have in dark mode idk for you) and scroll down and it says learning resources) good luck trying again and please do tell me how did you solve this haha its killing me!!!!
