Model the bodies that comprise your multibody system. Treat each body as a group of rigidly connected solid sections. Represent the solid sections using the Solid block and connect them using Rigid Transform blocks or direct frame connection lines. For an overview of the body modeling steps, see Creating Body Subsystems. For an example showing how to model a body, see Model a Compound Body.
