I created a Solidworks model of the Peaucellier-Lipkin linkage to better visualize the kinematics of the linkage and to document my Solidworks CAD capabilities. I modeled several parts: pins, links, and brackets. The brackets have zero degrees of freedom to simulate being secured to the ground. The links are of lengths 50, 75, and 150mm from axis to axis.

I also generated a .gif animation to show the pure translation of the end joint (shown as the red pin). I have posted here all of the CAD files.
