A typo in my post a moment ago made me wonder if I should just add a letter to the word “linkage” and use that as the new name of the program. “Linkjage” has a certain ring to it. Oscillating input is something that I have thought about…

I moved the pink entry to a later position in the color table. Linkage should now have pink links only after there are more than 15 or 20 links in the mechanism. I started to notice that all of the images  that I was posting were a bit…

Curved Sliding Connector Paths are working! There is a type of configuration that is not handled by the simulator but the simpler situations are now handled. Valid Sliding Connector Curved Paths   Invalid Curved Paths   I am planning on improving the simulator so that it can handle…

I would just like to thank you guys for using the Linkage program. The feedback I’ve gotten has been great and being able to provide features that people actually want is a very satisfying software development experience. When I first added the sliding connector feature, I wasn’t aware…

This video shows how a link may look when it represents just the curved slider path and nothing else. I may also implement this for links with more than two connectors although it will be harder to make solid links look this good. Link as a Curved Path

I have not gotten to the more complicated sliding connector situations and have only dealt with the simple cases so far. The simple cases like the one in the image below was not too difficult to implement. Curved Slider Path The mechanism in the picture above has a…

I uploaded a new version of the Linkage program. This update has some new features and some bug fixes. Some of the features listed below were made available in earlier versions but are recent and worth noting here. Fixed small drawing glitch in solid links that caused a…

Circle Drawing Features   I created a mechanism to simulate the orbit of an imaginary moon around an imaginary planet. I am still working on some point movement prediction and math rounding error code but I realized while doing this that I had no way to visualize the…

I added the ability to set the linear actuator throw distance in the Link Properties dialog box. I threw together this quick test mechanism and added to the sample gallery so that there would be a sample that had points, lines, and measurement lines. New Throw Distance Setting…
