One of the most important part in Geometry is recognizing the cuts of 3D-shapes .We are trying to show you this issue in easy ways and in different parts may teach how to use software for building shapes and take your doing easily. Our first lesson is about Cones and its cuts. Imagine you are going to cut two cones top to top in different directions . As you know 3D- shapes have three direction X ,Y & Z that X ,Y use for surface "two dimension width and height" and Z use for deepness . Now look at the animation of cutting shape in different deep. You can see the cutting in left animation. |

When the section plane is parallel to horizon sections will be circles. Do you know when the cutting, show a point? |
