Orthogonal View into Perspective
As a designer you need to be able to quickly visualise and draw an object or product in perspective that is accurate and realistic.
Starting by drawing the object or product from it's orthogonal views (Plan, Front & Side Views) is a great way of ensuring this so that you can easily and accurately transfer this into perspective. Later on when you get used to drawing objects using this method you will be able to go straight into drawing the object without creating an orthographic of the object.
How to Divide a Rectangle in Perspective
The diagram below shows you how to divide rectangles in Orthographic and Perspective to find specific points/intersections that would enable you to accurately draw an object/product
How to Multiply a Rectangle in Perspective
The diagram below shows you how to multiply a rectangle in orthographic and Perspective to find specific points/intersections that would enable you to accurately draw an object/product
Summative Task 1
Below is an orthographic view drawn on grid paper of a 'block' that has sections removed and tapered edges. Study this orthographic projection and attempt to draw it accurately in Perspective using the 'Divide & Multiply' methods in perspective. Click here for the rubric for this summative.
