Arahan Operasi
This ruler is a versatile tool for various drafting, drawing, and measuring tasks. Below are common uses:
1. Basic Measurement:
- Place the ruler flat on the surface of the material to be measured.
- Align the '0' mark of the desired scale (inches or millimeters) with the starting point of your measurement.
- Read the measurement at the endpoint. The transparent design allows for precise alignment with underlying lines or objects.
2. Drawing Straight Lines:
- Position the ruler firmly on your drawing surface where you intend to draw a line.
- Hold the ruler securely to prevent slipping.
- Use a pencil, pen, or other drawing instrument to draw along the edge of the ruler.
3. Utilizing the Zero Centering Scale:
- Locate the '0' mark in the center of the ruler's zero centering scale.
- Align this central '0' mark with the point from which you wish to measure outwards symmetrically.
- Measurements can then be read equally to the left and right of the center point, simplifying tasks requiring symmetry.
4. Using Graph Markings:
- The grid lines (8ths graph and 16ths to the inch) are useful for drawing parallel lines, creating grids, or aligning objects precisely.
- Align one of the grid lines with an existing line or edge on your paper.
- Use the other grid lines to draw parallel lines at desired intervals.
