# Unigine::BodyRope Class (CPP)

**Header:** #include <UniginePhysics.h>

**Inherits from:** BodyParticles


This class is used to simulate [ropes, cables, wires](../../../principles/physics/bodies/rope/index.md), etc. This body uses the [Mass-Spring model](../../../principles/physics/bodies/rope/index.md#model) for simulation, ensuring the rope ability to [fold, stretch](../../../principles/physics/bodies/rope/index.md#stretching) and even [tear](../../../principles/physics/bodies/rope/index.md#tearing). Unlike the flat [BodyCloth](../../../api/library/physics/class.bodycloth_cpp.md), they always preserve the same number of polygons in cross-section as in the source rope mesh. It means, the rope, when twisted, will never appear flat.
