This is one of the most common topics of discussion in the community of mechanical engineers and designers alike. Beginners who are new to the concept of orthographic drawings often get confused about the two and if you’re one of them, you’re not alone. Ask any professional with a hands-on experience of design and tools, he or she will say this is nothing but the means of representing three-dimensional objects in two dimensions. First and third angle projection are nothing but ways of describing what an object looks like from different directions. This is called orthographic projection and orthographic is nothing but engineering drawings or plan views. Now that you understand the concept of orthographic projections, let’s discuss the difference between first and third angle projection. What is First Angle Projection? This is one of the most common methods used to obtain engineering drawings, mostly for orthographic projections. Orthographic projection is a graphical method used...
