3-D models are graphic and mathematical representations of real or imagined physical structures. Artists, designers and drafters use computer-aided design (CAD) programs to create these models, which can represent everything from clouds, to models of the atom, to humans. Making a model of a 3-D boy or girl builds skills you can apply to other 3-D models, and to other 3-D projects that use these models. For example, you can convert your 3-D boy or girl into a model with a poseable armature (i.e. skeleton), which you can then animate within a 3-D game, simulation or short film.

Download, make or locate an image file displaying the front of a boy or girl.
Open your CAD program and click its "Create" or "Draw" menu heading, followed by the "Plane" item in that heading. (Search your program's help file on topics related to object creation, to locate your program's equivalents for these headings and items.) You'll load the child's image onto this plane, then create your model from the image.
Drag in the drawing window to create the plane, then click the mouse to end plane creation mode.
Click the menu or toolbar item that opens your program's material and texture toolset, which allows you to apply images and simulated textures to 3-D objects.
Click the button for creating new materials from bitmapped images. Find this button's specific name by searching your program's help file for "bitmaps."
Open, using the file dialogue box of the bitmap tool, the child image file from step 1.
Drag the bitmap you just loaded onto the plane from step 2. The plane will display the child's image.
Click the "Create" menu's "line" or "spline" drawing tool.
Drag the mouse pointer directly over the image of the child in the plane. This action creates an outline of the child. You'll expand this outline into 3-D space to form the child's 3-D model.
Click your program's "Extrusion" tool, which your program will list under the "Modifier" or related menu. (Extrusion expands 2-D shapes into 3-D objects.)
Click the outline, then drag to extrude the child's outline into a 3-D model.
Load, using the instructions from steps 5 to 7, the child's image file (from step 1) onto the 3-D model you just extruded.
