18. Teeth

This exercise was designed to illustrate the use of the “multiple copy on faces with variable scale” feature. The concept is the following: 1. Make the object to be copied. (Here it is a cone, which roughly resembles a tooth.) 2. Prepare a surface with different sized faces. The object will be copied on these faces (like the teeth in a jaw?). 3. Duplicate and give a size to each object that is proportional to the size of the face onto which the object is copied.

Half jaw

q Tool: Duplicate with variable scale q Open the model file: D01 q Do it: 1. The cone is the current object. 2. Select the Duplicate tool and press the spacebar to be in the multiple copy mode. 3. Click on the surface with different sized faces. 4. Then click on the “variable size copy icon”. 5. With the wand (+ Click) select the reference face. This face defines the size ratio between the face and the copied object. The reference face is the scale 1 for the object. The other objects will be copied proportional to the size of the face where they are copied. You might want to use this tool for making scales (of a fish) or other multiple objects with variable scale. q See the detailed explanations in the chapter: User Manual/Tools/Assemble/Duplicate/Multiple copies along a path or on the facets of an object
