Here is an easy way to understand first angle projection. Imagine an observer looking at the car using binocular that is moving towards him. This single image is what I imagine to remember the symbol correctly. You will understand why I chose a moving car instead of any stationary object while reading the article Third Angle Projection Symbol – What is it – How to remember.
In this article, we will mainly see what is the symbol for third angle projection of and how to remember it easily. Before that, please read the article “First Angle Projection Symbol – What is it – How to remember”. I will list down some important points to remember as well.
In technical drawings, orthographic two dimensional views are drawn at right angles to represent three dimensional objects. These views are drawn mainly using two schemes.
