I have the user interface in the Linkage program working somewhat. I have a serious dilemma with the simplicity of it. The concepts are good, but the details are troublesome. I’ll explain. Various gear Configurations In the image above, there are four gear interface situations shown. The user…
Continue readingI have a little bit of the user interface working. I took out an optimization feature where joining a lone connector to another connector would just discard the link that was part of the lone connector. Now, a lone connector might have a link that is a gear,…

Continue readingI discovered that my code was using the screen zoom in one of the DXF export calculations, and that the math used to guess at a good connector radius was not quite right. After fixing those two issues, I also made a change to improve the solid link…
Continue readingThe Linkage program is showing a really weird bug. Bug In the picture, it is obvious that the dotted line that is the arc between two connectors A & C, is not passing through the sliding connector D. This gets worse with time until the triangle shaped link…
