Linkage is a Windows-based mechanical-engineering application developed by David Rector that provides a specialized environment for the parametric design, real-time simulation, and kinematic analysis of planar linkage mechanisms. Intended for engineers, hobbyists, and educators, the program lets users sketch bars, joints, and anchors on an infinite grid, define precise dimensions and constraints, then immediately animate the resulting assembly to observe motion paths, velocity vectors, and force transmission. Common use cases range from prototyping cam-driven packaging machines and optimizing suspension geometry for small vehicles to creating classroom demonstrations of four-bar linkages and quickly verifying that a planned mechanism will clear surrounding hardware before any metal is cut. Because the solver runs continuously in the background, every edit—whether lengthening a crank, relocating a pivot, or adding a spring-damper—updates the animation on the fly, giving instant visual feedback on Grashof condition, toggle positions, and transmission angles. Export options generate DXF sketches for CAD refinement, CSV tables of coordinate data for further numerical analysis, or SVG frames that can be stitched into presentation videos. The single-version release, 3.16.42.0, ships as a lightweight, portable executable that requires no installation, stores each mechanism in human-readable XML, and supports both imperial and metric units. Linkage is classified under Engineering / CAD / Simulation and remains the only offering in its product line. The software is available for free on get.nero.com, with downloads served through trusted Windows package sources such as winget, always delivering the latest build and enabling batch installation alongside other applications.
