The Cone.

 

cone1.gif (1065 bytes) The cone, like the pyramid, is a perfect tool to use for making a roof.

All sides of the cone are made using triangles. You can also use 3 points to delimit the surface of the texture to be applied to each side of the cone.


Only two variables are needed;
the Cone diameter and the Cone height.

You can have several sides to a cone but I would not recommended making a 20 sided cone unless you have a really big shape to design.

There is one very important point to take into consideration here, the Diameter.

If you need to make a very small cone, like one with a diameter of 3 or 4 meters, you may encounter a compilation error. When you save the file you may get a message saying the polygon is corrupted.

This means, that for small objects, you must increase the size of both your diameter and height. If you multiply the real sizes, let's say by five times, and use a scale of 1/5, or 0.20, that will give you the right size for the object and it will compile correctly. You can also see more scale options
