The main purpose of this project is to use asymmetric polygon shapes. I will explain how to do it step by step. All measurements in the example are based on a scale of 1/32.

Sequence 01: We start by making the main piece of the truck. You can see below the rounded effect applied to the corners of the base. |

Sequence 02: The front side of the truck uses two Polygon sequences - one small polygon to give a rounded shape to all corners and a second polygon to cover the rest of the front engine side of the truck. This is the first polygon description. We now need to make a small piece in the front capot side of the truck. We need to not only give a rounded corner shape but also a rounded front shape. For the front round shape we will move the top points of the polygon to the center of the truck. The right hand diagram shows the bottom points in blue and top points in red. You can see that points 1, 2, 3 and 4 have been moved on the top surface of the polygon. |

To position the top
points coordinates to a different coordinate from the bottom ones you
have to first uncheck the Synchronize points changes
as shown on the left. When any point on the base doesn't have the same coordinates as the top points you will get a warning message telling you so. I will also raise points 5 and 6, just a little bit, to start giving to the polygon the required front angle.

Sequence 03: The second polygon used on the engine side of the truck. Notice that points 3 and 4 are also raised so the top side will be at a given angle. |

Here we can see the positions of the first 3 sequences or parts of the truck. |

Sequence 04: We now need to add a small part to align the front engine section with the rest of the truck as shown here. |

Sequence 05: This is the front cabin part of the truck. If you take a closer look at the cabin you can see that we can made it using a polygon with a larger base than the top section. |

The left graphic shows both sections superimposed. The angle of the cabin is given by the plane made by the points 1 and 2 from the base and 1 and 2 from the top. |

Sequence 06: Now we complete the rest of the truck by adding the entire section behind the driver's cabin. Note that the roof is not made as it is much better to use another polygon to give a rounded shape. |
![]() |
Sequence 07: For the roof I use a polygon 1 meter high and move the top points to the center to create a rounded shape all over it. |
![]() |
Sequence 08, 09, 10 and
11: We need to start covering the wheel section now. This sequences uses a polygon placed in a horizontal position. This part has a cavity
to allow showing the wheel inside it. Therefore we will only draw
the internal back side as well as the internal sides 2 to 6. |

Sequence 12, 13, 14 and
15: Finally we place the wheels using the wheel tool. A wheel is made very quickly if you use a small texture like 32x32 or 64x64 pixels. I use the NOVA051 texture for this purpose. This will finish the truck. |

Finally, and this is very
important, we have to maximize the macro since we have identical parts
but placed at different locations.
All the wheels and wheels covers are maximized. You can see that wheel covers 3 and 4 are rotated 180 degrees. If we consider that wheel covers 1 and 2 are in my front view I will need to rotate the back two wheel covers 180 degrees to make them visible from the right side. |
