Hello Daily AutoCAD readers,
In the second article of my series of articles about 3D modeling, I will explain about the primitive solid entities. In Fig. 1, you can see all of these entities together. Instead of explaining how each entity is drawn in AutoCAD, I will give you some figures that show the physical structure and what are the variables that AutoCAD needs to draw these entities.

Fig.1
Let’s learn about these primitives one by one:

Fig.2 Box

Fig.3 Wedge

Fig.4 Cone

Fig.5 Cylinder

Fig.6 Pyramid

Fig.7 Torus
These are the primitive shapes that you can use when making 3D solid modeling. You may also remember these shapes from high school. You can call all of these shapes can be drawn by calling from DASHBOARD that we have placed on screen as described in the previus lesson. I will explain command options in detail in my future articles. So, I am giving only the representing figures.
Good bye.

I am trying to use the torus command to acheive a football shape, but the radius of both axis that results is incorrect. I feel like I’m missing a step in acheiving the desired shape. Any assistance you can provide would be greatly appreciated.
