# Inline Instruments / Relief Valves Class

Typically you don't need to make any changes to the Inline Instruments or Relief Valves classes, because when you later will configure PlantSpecDriven with [The Wizard](/plant-tools/plantspecdriven/how-to-use/configuration/the-wizard.md) the properties from Inline Assets and its sub-classes will be created automatically for the Inline Instruments classes and its sub-classes.

All properties will be created for the Inline Instruments class with the exception of the Size2 property.

This is because the Relief Valves class already has a Size2 property.

[The Wizard](/plant-tools/plantspecdriven/how-to-use/configuration/the-wizard.md) will take of this and add the Size2 property for all sub classes under the Inline Instruments class.
