Product Description: Quantity: 1 piece Name: Multifunctional compass ruler, multifunctional drawing ruler, scale, proportional divider Color: Black Size: 26*1.8cm Product standard configuration: a single pearl bag, including a 3-head scale (1 for green/blue/orange). Function description of the multifunction drawing scale: 1. The multi-functional drawing ruler can be used to transfer the subject to canvas or paper while maintaining proportion. easy to use. Increase, decrease or measure the size to be drawn. Ladder dividers measure 10" x 0.5" x 0.25". 2. The multi-functional drafting ruler is convenient for architects and artists to transfer different measurements to paper while maintaining the same scale. This ensures that the drawings are scaled relative to each other. 3. The multifunctional drafting ruler is made of strong tempered plastic POM (commonly known as racing steel), 10 inches long. 4. Easy to Use: Multifunctional drawing ruler is the best secret to improve your drawing, this easy to use tool scale divider can transfer subject file to canvas or paper. Take the guesswork out of painting anytime, anywhere. 5. WIDE RANGE OF USES: Scale dividers allow sketchers or artists to create exact scale replicas of the original paintings. Suitable for many fields including art, architecture and engineering etc. 6. Precise production: Proportional valves are precise, pocket-sized and require no special electronics, so they are popular tools in these areas. Artists have found that proportional dividers are particularly useful for transferring very small proportions that might otherwise be difficult to reproduce. Instructions: With the Ruler Scale Divider Versatile drawing, you can easily make incredibly realistic drawings. Learn how to use it in minutes and draw like a mast. Step 1: Slide the locking clip up up and down to adjust the scale, move the green tab towards the middle of the dispenser to reduce the size of the transfer. Move the green tab towards the end to enlarge the transfer size. Step 2: Hold the proportional valve with one hand and extend your arm directly in front of you. Then place the item to be drawn in the window with the small opening in the scale divider. Adjust the divider with one hand until the two pinpoints on the short end accurately reflect the distance of objects. Step 3: Bring the proportional divider back to your drawing paper or canvas and use a pencil to mark the length created by the largest opening in the divider. Since the proportional divider operates on a pivot, the small and large apertures are proportional to each other. So even if you are measuring an object with a smaller aperture, a larger aperture transfers the measurement to a larger scale. Step 4: Continue to measure the object through the small opening in the scale divider and transfer the scaled measurements to graph paper. Use these measurements to draw scale artwork. hint: Carefully place the scale divider on the drawing paper or canvas to keep the legs from moving. Even a slight movement makes the proportions imprecise. Always measure objects using the scale dispenser with the arm fully extended to maintain consistency of measurement method.
