DRAWING INSTRUMENTS AND MATERIALS.

Drawing instruments are tools used by artists, architects, engineers, and designers to create accurate and precise drawings.

The following are common drawing instruments and their uses:

  1. Pencils: Basic tools for sketching and drawing, available in various hardness grades.
  2. Erasers: Used to remove or correct pencil markings on paper.
  3. Rulers and Scales: Straightedges with marked measurements for drawing straight lines and measuring lengths.
  4. Compasses: Instruments for drawing circles or arcs of specific diameters.
  5. Protractors: Used to measure and draw angles accurately.
  6. Triangles: Typically made of plastic or metal, used for drawing straight lines and angles.
  7. Drafting Compass: Similar to a regular compass but designed specifically for drafting and technical drawing.
  8. Templates: Pre-cut shapes or symbols that can be traced for consistent and precise drawings.
  9. T-squares: T-shaped rulers used in combination with drawing boards for straight-edge drawing.
  10. Drawing Boards: A flat surface on which paper is placed for drawing, often equipped with parallel rulers or T-squares.
  11. Technical Pens: Precision pens with various nib sizes for detailed and technical drawings.
  12. French Curves: Templates with curved edges used for drawing smooth curves.

These instruments help professionals and artists produce drawings with accuracy, clarity, and consistency. The choice of drawing instruments depends on the specific requirements of the drawing task and the desired level of precision.
