Points to note when making a drawing using first angle orthographic projection: 1. Corresponding heights in the front view and side view are the same. For example, the height of the hole from the base, H, is the same in both front and side views. The thickness of the base, T, is .

The general recommendation are that thick lines are twice as thick as thin lines. A thick continuous line is used for visible edges and outlines. A thin line is used for hatching, leader lines, short centre lines, dimensions and projections.

Note: 1. ORTHOGRAPHIC PROJECTION INTRODUCTION Any object has three dimensions, that is, length, width and thickness. A projection is defined as a representation of an object on a two dimensional plane. The projections of an object should convey all the three dimensions, along with other details of the object on a sheet of paper.

To obtain an orthographic projection, an object is placed in an imaginary glass box as shown in Figure The sides of the glass box represent the six principle planes. Images of the object are projected onto the sides of the box to create the six principle views. The general recommendation are that thick lines are twice as thick as thin lines. A thick continuous line is used for visible edges and outlines. A thin line is used for hatching, leader lines, short centre lines, dimensions and projections.
