Assembly

Connect bodies through joints, gears, and constraints

Assemble bodies into multibody systems. Use joints, gears, and other constraints to model the relative degrees of freedom between bodies. Specify joint state targets to guide model assembly. For an overview of the multibody assembly steps, see Assembling Multibody Systems. For an example showing how to assemble a multibody system, see Model Double Pendulum.
