Linkage Program

I’m not sure what to call them. On an actuator, there is a small circle that can be used to change the throw length. That little circle is an adjuster knob or adjustment controller or something like that. I’m working towards in-mechanism editing of cams and changing the…

A new version is available in the usual place. I was finally able to spend the hour needed to fix the crash that happened when deleting links that were fastened to gears (or vice-versa). Version 3.3.13 has this fix. A few other changes and fixes: You can now…

The whole “fastening” thing is a bit troublesome for me. I originally wanted to be able to move drawing elements with links and decided to allow “fastening.” This worked pretty well, though there is a bug where deleting a fastened element somehow causes a crash. But fastening isn’t…

I have a new Beta test version of the Linkage program. This version has an okay link triangle handling feature as well as a few connector alignment tweaks. it also has a way of selecting links and connectors by name or identifier. It’s still all being tested by…

I have a first draft working for the link triangle simulation. Like I said recently, I am opting to support the most common type of link triangle configuration and ignoring all others. Here are videos of the two variations of supported link triangles: What I did on this…

I decided that I’m going to make an alternate link-to-link simulation function that accepts a link triangle as one of the links. It won’t work for both to start with because, well, no one makes mechanisms like that. The fact is, there’s only really one type of link…

I got my new code singing certificate and I fixed a few minor bugs. Super short dimension lines were becoming infinite due to the space calculated for the arrow heads. There was also a problem with gear and link rotation angles that went wrong after about two rotations…

I have a plan. It’s not a very good plan, but it is a plan. The mechanism above presents a problem that I have written about a few times in the past. The EGJ triangle is what I call a “link triangle.” It is a set of links…

Somehow, I missed that my code signing certificate was about to expire. And Symantec needs me to do the whole notarized identification thing to renew it. This means that I can’t produce a new Linkage program with a bug fix that I wanted to distribute, at least not…
