This is my second time attempting to make something on solidworks. I calculated my dimensions from the exact rules and constraints needed (based on the radii and center lengths and slot numbers etc), plugged in the exact values (like using 2^0.5 instead of rounding), and still it doesn't work, in fact I got interference. So I added clearance, and it still doesn't work even without the interference. I get this red bar on the timer, it doesn't even jam, I think the computer just stops trying. 

So, I go and find a tutorial on youtube. I copy their exact dimensions, I copy their exact motion study settings, and still it doesn't work. Matter fact I get interference here too even though it worked in their video. So now I'm thinking that it has nothing to do with my math and dimensions, but instead it's my settings or something. 

i uploaded two attatchments. one where the pin is slightly smaller than the opening, and one where theyre the exact same size. neither of them work
