French Curves and Set Squares (for drawing office use)

Abstract

I. Product and its Uses French curves are used commonly for drawing large or composite curves on drawings. They are also called as architectural french curves generally made of transparent plastic sheet The thickness of French curves is generally 'not more than 2 mm. A set of six french curves large or small sizes are used. Curves from No. 1-90 mm to No. 24-12" or 300 mm are in use. Set square are used commonly for Geometrical drawing surveyors and Engineers for measurement of angle or laying angles. This is also widely used by Schools, College students for preparing Geometrical lining and drawings. They are used by Engineers, architects etc., surveyors and draughtsman. They are available in sted sheets also. They are made of transparent Acrylic plastic in two process-one is moulded process and Acrylic sheet cutting process. But this project has been based from transparent Acrylic Sheet in cutting process.
