==Description==

The [[Image:Reinforcement_SlabRebars.svg|24px]] [[Reinforcement_SlabRebars|Reinforcement SlabRebars]] tool allows the user to create reinforcing bars inside a Slab [[Arch_Structure|Arch Structure]] object.

This tool is part of the [[Image:Reinforcement_Workbench.svg|24px]] [[Reinforcement_Workbench|Reinforcement Workbench]], an [[External_workbenches|external workbench]] that can be installed with the [[Image:Std_AddonMgr.svg|24px]] [[Std_AddonMgr|Addon Manager]].

In this example we will create Slab Reinforcement for Slab spanning in one direction as shown in below figure.
