Our spacecraft needs a few weapons and guns attached to the wing to make it more interesting. And that's what we will do now! To create guns and weapons for the model, select the faces pointed in the following image and extruding them three times. The object created with this move will be the base for the two weapons that will be attached to the wing.
When the extrusions are finished, add two new edge loops to the model right where the next figure shows. Use the middle mouse button to add the loops at the middle point of each face (section A).
The weapon model that we will create has a cylindrical shape, and to create a shape like this, we need a circle or cylinder to start. There is an easy and quick way to mix the shape of a square and a circle in Blender, which we will see next. To start, select the faces shown in the previous image (section B) and erase them. Erase the faces, but leave the edges around the deleted faces selected.
