<p class="has-luminous-vivid-amber-background-color has-background"><strong>INTRODUCTION</strong></p> <!-- wp:paragraph --> <p>Working drawings, or orthographic projections, are drawn to scale. A scale drawing shows a real object with all its dimensions in proportion, but the object is shown bigger or smaller than it really is. The amount by which the drawing is enlarged or reduced is called scale, or the scale factor.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Scale drawings are used to illustrate items that are not convenient to draw at their actual size. This may be because drawing the item at full size would be unmanageable, or would not easily fit on a single sheet of paper (such as a building), or alternatively because items need to be drawn larger than full size to adequately represent all the detail that needs to be communicated (such as a complex connection).</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Scale drawing is a drawing which has been reduced or enlarged from its original size, to a specified scale. The scale of drawings is described as a ratio using the notation.</p> <!-- /wp:paragraph --> <pre class="wp-block-preformatted has-normal-font-size"><strong>Reading Graduation on the Meter Rule <div class="sign-up-notice-after-excerpt-two" style="background-color:powderblue;"> You are viewing an excerpt of this lesson.
