Crossed Hinges Simulator

A web-based interactive tool for engineers, designers, and makers to design and analyze cross (X-shaped) hinge mechanisms for boxes with hinged lids. Real-time visualization and analysis of four-bar linkage mechanisms.

• Interactive Design — Drag-and-drop pivot positioning with real-time visual feedback
• Motion Simulation — Animate the lid opening/closing to visualize the full range of motion
• Geometric Analysis — Automatic calculation of link lengths, angle limits, and minimum clearances
• Motion Path Visualization — See the trajectory of the lid corners throughout the opening motion
• Configuration Management — Save and load hinge configurations for different box designs
