Thanks to a user, I fixed a few bugs in the spline/cam simulation code. Splines that are not fastened to a link or connector are now treated as part of the “ground” and can be used as cam-like shapes without producing simulation errors. Speaking of connectors; a cam…
Continue readingI was just looking at http://www.snappyxo.com and their site mentioned that they had the first planar linkage design software. I sent a contact form letting them know of their mistake and I got a really nice reply from the CEO that he knows they are not the first…
