## Transform Manipulators

Objects in 3D can be transformed to alter how they are viewed. Below are the three most common transformation operations.

Transformations occur on three axes - X, Y and Z. Clara.io uses a right handed coordinate system where X points right, Y points up and Z points out of the screen.

• The translation of an object refers to its position. Position in 3D space is measured as an offset from the origin in the three axes.

• The rotation of an object refers to its angle. Rotation in 3D space is measured as the angle offset around the axis. In Clara.io the angle is measured in degrees. In some spaces, the axes of rotation are referred to pitch, yaw and roll representing X, Y and Z respectively.

• The scale of an object refers to its size. Scale in 3D space is measured as a stretch or squash factor along an axis.

There are two methods of transforming an object.

### Manipulators

Manipulators are visual handles that allow you to drag the mouse to perform transformations. They are accessed by using the Move, Rotate, and Scale tools in the Selection Panel. These tools display a manipulator over the current selection and will transform all selected objects.

Each axis of the manipulator is colored for easy recognition.

• The X axis is red
• The Y axis is green
• The Z axis is blue

In the case of Move and Scale, between each pair of axes exists a square representing a plane defined by two axes.

• The XY plane is yellow
• The XZ plane is magenta
• The YZ plane is cyan

To use a manipulator, click and drag over one of its axes or planes. This will turn the axis or plane yellow and transform the object in that direction. ### Transform Properties

The second method of transforming an object is to use its Transform Properties (found in the Properties panel under the Transform rollout). Here, Translation, Rotation and Scale are represented as XYZ fields and can be manipulated numerically. This method is recommended for precise operations. These fields can also be handled by dragging up or down from the field. ### Transform Coordination

The Transform Coordination feature allows you to choose between World (also known as Global), Local, and View. You can learn more about these features here.
