Lesson Note on BASIC TECHNOLOGY for JSS3 FIRST TERM MS-WORD Price: € 5 This lesson note covers all 3-terms and serves as a reference material to help teachers draw out their lesson plan easier, saving you valuable time to focus on the core job of teaching. ORTHOGRAPHIC PROJECTION I. Each question in Section A is followed by four options, choose the correct option for each question and shade the correct answer corresponding to […] While isometric drawing looks at all the three views (or faces) of an object together, orthographic looks at the same three views separately but linked together. Definition (Define Enlargement and Reduction) II. There are two main methods or orthographic projection as earlier said, they are: The principal views are the front elevation side (end) elevation and the plan. this way both planes are brought in the same plane containing vp. You might think that orthographic projections are of no use today. Suppose you want someone in another country to design this triangular structure for you. Orthographic projection, common method of representing three-dimensional objects, usually by three two-dimensional drawings in each of which the object is viewed along parallel lines that are perpendicular to the plane of the drawing.
