<p>Next, add a <em>Nose cone</em> to the design by clicking the
corresponding component addition button. This opens the nose cone
configuration dialog.

<p>The configuration dialog contains settings for the nose cone shape,
dimensions and material. Set the nose cone length to 10 cm,

<p>The design window displays the nose cone. Next, add a <em>Body
tube</em> to the design.

<p>Change the body tube length to 25 cm. The <em>Automatic</em>
option for the outer diameter is ticked by default, in which case the
diameter is automatically the same as that of the nose cone.

<p>Next, add a <em>Trapezoidal fin set</em> to the rocket. The body
tube must be selected in order to add the component.
