📄️ Overview
The Geometry panel in MotionGen provides powerful tools for performing classical geometric constructions used in mechanism and linkage design. These constructions form the foundation of graphical synthesis methods that have been used by engineers for over a century.
📄️ Using the Geometry Panel
The Geometry panel provides tools for creating geometric objects such as points, lines, segments, and circles. These objects can be used to perform classical geometric constructions for mechanism design.
📄️ Essential Constructions
Before diving into linkage synthesis, it's helpful to understand some fundamental geometric constructions using compass and straightedge.
📄️ Two-Position Synthesis
Two-position synthesis is used to design a four-bar linkage that moves a body between two specified positions. There are two common cases: Crank Output and Coupler Output.
📄️ Three-Position Synthesis
Three-position synthesis is used to design a four-bar linkage that moves a coupler through three specified positions. There are two common cases: Finding Fixed Pivots and With Fixed Pivots.
