# Getting Started - Chapter 2 - Mesh Placement

## Place and Scale a Mesh

### Size

Some meshes, such as box, have properties that you can set to change during their creation.

const box = BABYLON.MeshBuilder.CreateBox("box", {width: 2, height: 1.5, depth: 3})

After creation, and for meshes that do not have sizing options, changes in size are achieved by scaling the mesh.

const box = BABYLON.MeshBuilder.CreateBox("box", {}); //unit cubebox.scaling.x = 2;box.scaling.y = 1.5;box.scaling.z = 3;
const box = BABYLON.MeshBuilder.CreateBox("box", {}); //unit cubebox.scaling = new BABYLON.Vector3(2, 1.5, 3);

As you can see, from the above codes, scaling is a vector object with properties x, y, and z.

All three of the above sets of codes will produce boxes of the same size

## Position

For the majority of meshes the position property places the center of the mesh at that position. Position is also a vector object with properties x, y, and z, so that the following two sets of codes position the box in the same place.

box.position.x = -2;box.position.y = 4.2;box.position.z = 0.1;
box.position = new BABYLON.Vector3(-2, 4.2, 0.1);

We can now use positions to place the boxes sized in three different ways in one playground. In each case the height of a box is 1.5 and therefore for each box position.y = 0.75 to place it on the ground.

Positioning Meshes

### Orientation

As for scaling and position the rotation property of a mesh is a vector object with properties x, y and z. However when building our first world we will only consider rotation about one axis since a setting a rotation about all three axes can be surprisingly confusing.

Rotations are given in radians. If you prefer working in degrees Babylon.js provides a conversion tool. Both these lines of code will produce the same rotation.

box.rotation.y = Math.PI / 4;box.rotation.y = BABYLON.Tools.ToRadians(45);
Rotating Meshes

We can now change the size, position and orientate a mesh adding a little more variation to the box as a building. Before we place more boxes in the scene let us see if we can make them a little more building like.
