They are marked with a range of scales or ratios, used for making or measuring reduced-scale drawings like blueprints or floor plans.Ī metric ruler, also called a rule or, especially in the printing industry, a line gauge, is a measuring instrument used in technical drawing, geometry, engineering, printing and construction to rule straight lines and calculate distances.
Triangular scale rulers, scale-measuring devices that are triangular in shape, are used by architects, engineers, builders and designers. Scale ruler (plural scale rulers) A ruler marked with a range of calibrated scales (ratios) for drawing and measuring from reduced scale drawings, such as blueprints and floor plans.
There are many variations of these basic tools.
The types of tools to measure angles fall into one of three categories: protractors, squares and compasses. What are 3 devices used to measure angles? To measure the size of angle ABC, place the protractor over the angle so that the centre of the protractor is directly over the angle’s vertex, B and the base line of the protractor is along the arm, BA, of the angle. The two scales make it easy for us to measure angles facing different ways. This is worked out by dividing the real life size (100cm) by 50 (1:50 scale). So, if we were drawing a table that measured 100cm wide by 200cm long at a scale of 1:50, you would draw the table 2cm wide by 4cm long on your piece of paper. You could also say, 1 unit in the drawing is equal to 100 units in real life. An architect uses the scale ruler to convert dimensions into a smaller drawing of a building plan. How do scale rulers work?Ī scale ruler is the three-sided ruler used by architects and readers of blueprints to convert between scaled drawings and the actual dimensions without having to resort to any mathematical calculations. Double click finishes the selection of points. The example is for a scale of 1:200 Click OK Continue with measuring. Enter the scale you want for this particular measurement. Select the line, triangle or shaded triangle in the Measuring toolbar depending on what you want to measure. Drafting Triangle Drafting triangles, usually made of clear plastic, are used to measure angles and draw vertical or inclined lines.
