3D models are used for a variety of purposes, from movies, video games and ads to medical and architectural animations. You used to have to be a graphic artist with access to an expensive and complex 3D modeling program to create a 3D model. There are now several easy-to-use and inexpensive modeling programs that will allow you to create your own 3D models. In this article, the Hexagon program will be used to create a 3D pushpin used for holding paper on bulletin boards, but the techniques used are applicable to almost any 3D modeling program.
1. Open the Hexagon program. Click on the “Primitives” tab and select “Cylinder.” Go to the “Perspective” view and draw the cylinder. Make it about twice as high as it is wide.
2. Go to the “Selection” modes at the top and change to “Edges.” Select the top edge of the cylinder. Use the “Scale” function of the “Universal Manipulator” tool to make the top of the cylinder slightly wider than the bottom.
3. Select the “Vertex Modeling” tab and click on the “Tessellation by Slice” tool. About one-sixth of the way up the cylinder, click with the tool to create a new edge. Use the tool to create another edge about one-quarter of the way down from the top. Use the “Scale” function of the “Universal Manipulator” tool to make the width of these two edges slightly smaller, thus moving the surface between the edges inward.
4. Select the “Primitives” tab and click on “Cone.” Draw the cone in the view. Then use the “Scale,” “Rotate” and “Positioning” functions of the “Universal Manipulator” tool to position the cone at the bottom of the cylinder to serve as the metallic point of the pin. You now have the shape of your pushpin.
5. Select the top part of the pushpin (the cylinder) and click on the “Materials/Shading Domain” tab on the left. Go to the “Materials” section and change the color to red or blue. Select the bottom part of the pin (the cone) and change its color to a light gray. Select “File,” click “Export” and then “Wavefront OBJ.” Name the file “Pin” and save it. You now have a 3D pushpin that can be imported into any 3D program.
