Step 1
Launch the Blender application. You will see its default preview, with a camera, a cube primitive and a point light in the scene.
Step 2
Before we start modeling, we have to remove the camera and the light from the scene. So select the Camera and the Light by pressing the Shift key and Right Clicking on each, and then press either the X or Delete key. A popup menu will appear in the viewport, select the Delete command to remove the selected objects from the scene.
Step 3
Now we need to setup the reference images in the front and the side viewports. So go to View > Front or press the 1 key on the Numpad to jump into the Front viewport.
Step 4
Press the N key to open the Properties panel of the selected viewport camera as shown in the image below. Here you can set the values for the front camera properties.
Step 5
Turn on the Background Images button and then click on the drop down arrow to expand the properties. Click on the Add Image button and then on the Open button.
