# Transformation

The transformation window displays the current transformation applied on your selection, relative to its parent (if any, else relative to the World Space). This is called Object-Space transformation.

It can be used to position with precision objects (or to correct a position).

## Relative positioning

The transformation window displays the relative transformation of your selection within its parent. (also known as Object-Space)

This means the transformation window allows you to control the position of the selected object within its parent and not the global transformation from the World Space.

![The first Geyser P7 is positioned at -50cm on X, within its parent. Position from World Space is 40cm on Y (inherit from its parent) and -50cm on X (inherit from itself)](/files/oPfaFbIioalvBz8XfO8k)

## Usage

The transformation is made of translation and rotation along 3 axes (X, Y, Z), where each of the axes can be adjusted by entering a value and clicking the "Apply" button.

### Position

To adjust the translation position from the transformation window, set the X, Y, or Z position value as needed:

### Rotation

To adjust the rotation angle from the transformation window, you can either:

* Set the desired value and press the "Apply" button,
* Or click on the square button to apply 45° increment.
  * Left click to rotate clockwise (CW).
  * Right click to rotate counterclockwise (CCW).

### Size

An additional Size parameter is available to adjust the scale of the selected object (where 2 means 2 times bigger and 0.5 means 2 times smaller).

### Reset

To reset each type of transformation, double click on "Position", "Rotation" and/or "Size". 

Apply the reset by clicking the "Apply" button.

### Cancel

Until you click on the "Apply" button, new transformation values are not applied.

To cancel the update, select another object (from any view or 3D hierarchy).

## Unit

If needed, you can change the current value unit. Right-click on the value to select another unit:

Note: the units displayed depend on your Depence preference.
