# Data for visualisation and collision monitoring

Tools and tool heads are displayed as graphical objects as part of machining simulation. An additional member of the kinematic chain, what is known as a linkpoint, is appended to the connected graphical tool objects for the purpose of visualisation.

The specific data required is transferred in the tool data at tool change and sent to the machining simulation by appropriate commands (#SCENE ..., V.G.WZ_AKT.LINKPOINT...@@[PROG]) in the NC program.

## Release Note

The availability of this function depends on the configuration and the scope of the version.
