? Linkage I don’t know if there is a name for this type of linkage. The green triangle link in the image above has a position (location and orientation) defined by the three ground connections and the lengths of the three connecting links. A search for equations to…

  Upon further inspection, A Stephenson value gear mechanism cannot be built with the Linkage program. I don’t have the necessary simulation code to handle the complexity of the links. The problem comes from the connection of the “Link” to the rest of the mechanism. The position of…

A user asked me about curved links in the Linkage program. I think that it is safe to say that curved slider paths is the desired feature because the visual representation of a link is fairly meaningless. It is the connectors that matter. Straight Sliding Connector The straight…

Computer monitors, the old CRT kind, scan from top to bottom like a TV. Before computers, that didn’t cause any problems but when people started accessing the screen, a new coordinate system (variation) was born. It was the “inverted” Cartesian coordinate system. Well, I don’t think that there…

It turns out that moving the sample gallery into the main menu was only a little bit troublesome and only took an hour for me to figure out how to fix. The problem appeared to be that the MFC code created a new gallery window of some sort…

The setup program now works correctly to update the Linkage program. It turns out that there are a few more manual steps I need to take when creating the installer (MSI file) so that an update actually updates the linkage.exe executable file. Microsoft really dropped the ball when…

I was contacted by a very helpful person who tried the Linkage program and had some very good suggestions. I fixed a few bugs and then implemented a few of the less complicated features that we discussed. Fixed a problem where I had added , and . shortcut…

Someone suggests adding the ability to lock the length of a link. After giving this some thought, I can think of a few ways to handle it. There are some complications though and I’m not sure how to handle them. First, the questions: If someone moves a connector…
