# Auto Pivot & Scale Calculation

After adding [**Buildable Grid Object**](../primary-components/buildable-grid-object) or [**Buildable Free Object**](../primary-components/buildable-free-object) component to your prefab, simply click on **Calculate Size & Pivot** button to do the calculation automatically. You can see the same process in the video down below.

For the objects that were originally prepared for the Grid Axis XY (Ex: 2D prefabs) set **Rotate Scale & Pivot For XY** property enable, then hit **Calculate Size & Pivot** button. You can see the same process in the video down below.

_**NOTE:** If you are having any issues with objects appearing below the grid level (especially 2D objects) simply manually offset the **Object Custom Pivot** values to fix your issues._
