No Splines as Links?

I’ve been torn on changing the test software from using splines as a sort of decoration on links into actual links themselves. There is no reason to drop in a spline as a drawing element then add a slider to it to turn it into a cam when the spline could just be a link with connectors. The only reason right now to leave it as a separate element is because links can be gears and it seems weird to have a link be both a gear and a cam. I’m still unsure about the direction to go with this but I do dislike the whole “fasten” idea for non-drawing elements. I also need to somehow deal with the parts list feature since the cams need to get into that and be on the links that they go with. Ugh, I’ve created a software monster but at least it’s fun to play with from time to time.
