I’ve been a bit lazy about updates. I updated the Linkage software to version 3.10.5 a few weeks or months ago. It’s no longer a beta program.

This new version has a method of simulating links that are positioned by three other links. the algorithm to do this is weird because it needs to do a mini simulation on just the three links and the one that connects them all together. Want to know more? Check out this set of posts:

I took some shortcuts and some mechanism fail during simulation. Others have trouble with getting multiple results that cause a jump in the position of the links. It’s experimental, for sure. So if you have a mechanism and a link is held in place by three other links, it cold fail. But hey, it’s better than before when it would not even try to simulate it!
