# Calculations

Calculations can be used in PlantDataManager as well. They work the same way and use the same calculation configurations as PlantExpressTools. You can define and update Calculations (see [Calculations)](/plant-tools/plantexpresstools/how-to-use/calculations.md).

The Calculation functions can be found under the Calculations menu.

As with Link Configurations, AutoCAD properties cannot be calculated within PlantDataManager. Therefore these calculations will be disabled automatically.

When updating calculations you will get a "Results" dialog.

Details about links can be found under [Calculations](/plant-tools/plantexpresstools/how-to-use/calculations.md).

There are also some cases where PlantDataManager fixes wrong calculations if they are either duplicate calculations or the file name is wrong. Details for that can be found under: [Correcting Calculations](/plant-tools/plantexpresstools/how-to-use/calculations/additional-information/correcting-calculations.md)
