Cách sử dụng
A pantograph is a tool used for copying or resizing a physical drawing or picture onto another surface. It works by using a system of rods and hinges to trace the outline of the original image and transfer it onto a larger or smaller surface, while maintaining the same proportions. Pantographs are commonly used in art, engineering, and architecture to create detailed and accurate copies of designs. They can be used with pencils or other drawing utensils, or with electric cutters or routers for more precise reproduction. Overall, a pantograph is a handy tool to have when trying to replicate a design or image with consistent accuracy.
