# Map

:lock: Map.**Show**

A **Map** can be seen as an instance of a **Map Definition**. It contains the actual data for each layer. A **Map** may be linked to a **Material** and the **Map** quantity can be synchronized with the **Material** quantity if the following conditions are met:

1. The **Material** master **Map** default layer must be of either type
2. The **Map** units must be defined and match either the **Material** *Primary or Secondary Units*.

!!! info
	Maps are part of Mapping which is a Critical Manufacturing optional module.

Internally, and also for loading and exporting, Critical Manufacturing uses the G85-0703 format. Please refer to [this link](https://store-us.semi.org/products/g08500-semi-g85-specification-for-map-data-format) for more information on the G85 format

!!! info
	The setting `/Cmf/System/Configuration/Mapping/CheckUpdatesAgainstMark` determines whether the system checks for every unit update or the unit is part of the Map Definition mask. If set to true, there is a performance penalty incurred for every update.

## Sequence of Steps

The necessary steps for correctly creating and using a **Map** are:

1. Create a **Map Definition**.
2. If it is intended to link the **Map** to a **Material**, create the **Material**.
3. Create the **Map**.
4. If it is intended to link the **Map** to a **Material**, link the **Material** with the **Map**.
