15+ Engineering Drawing Tools
1. Drawing Paper
Drawing Paper is specially made for drawing on.
Drawing Paper is a crucial tool for producing diverse drawings, ranging from creative sketches to intricate architectural designs.
It serves not only for manual artwork but also for printing physical copies of digital drawings. The type of Paper used depends on the specific kind of drawing and the desired outcome.
a. Types of Drawing Paper
| Type of Drawing Paper | Description | Suitable For |
|---|---|---|
| Bond Paper | Harder and more durable than ordinary papers. | Letterheads, Typed reports, Envelopes |
| Gloss Coated Paper | Coated with gloss, it is highly shining in nature. | Flyers and Brochures |
| Matt Coated Paper | Opposite of gloss-coated Paper, not shiny. | Reports, Flyers, and Leaflets |
| Recycled Paper | Made from recycled paper, it reduces environmental impact. | Reports, Memo papers, and Forms |
| Silk Coated Paper | Interim between gloss and matt, smooth coating. | Magazines, Books, and Catalogues |
| Uncoated Paper | Absence of coating, commonly used for official purposes. | Forms, Letterheads, Applications writing, Files printing, and Memo paper |
| Watermarked Paper | It provides a luxury and premium look with a watermark. | Documents, Exam Certificates, and Game Certificates |
b. Different Sizes of Drawing Paper
| Paper Size | Dimensions (cm) | Paper Area (m2) |
|---|---|---|
| A5 | 14.8 x 21 | 0.03108 |
| A4 | 21 x 29.7 | 0.0612 |
| A3 | 29.7 x 42 | 0.125 |
| A2 | 42 x 59.4 | 0.25 |
| A1 | 59.4 x 84.1 | 0.50 |
| A0 | 84.1 x 118.9 | 1 |
c. Weight of different drawing papers
| Paper Weight (gsm) | Feels Similar to: |
|---|---|
| 35-55 | Most newspapers |
| 90 | Mid-market magazine’s inner pages |
| 130-250 | A good quality promotional poster |
| 180-250 | Mid-market magazine cover |
| 350 | Most reasonable quality business cards |
2. Masking Tape
✔This tape is used for attaching drawing paper to a board without damaging it.
3. Pencil Sharpener
✔ A mechanical tool commonly used to sharpen pencils is known as a pencil sharpener.
4. Eraser
✔ To remove unwanted drawings or dirt from a piece of artwork, an eraser is the tool commonly used.
✔ A soft eraser is more appropriate for eliminating smudges and pencil marks, while a harder eraser is ideal for making changes and correcting errors in the drawing.
5. Drawing Pencil
✔ When it comes to sketching on Paper, the Pencil is an indispensable tool. Graphite pencils are the norm for drafting, and the grade of the Pencil depends on the type of work.
✔ For extreme precision and working with graphs, diagrams, and charts, hard pencils like 2H, 4H, and 6H are the best.
✔ For general-purpose drawing, medium pencils like H.B. are great.
✔ On the other hand, soft pencils like 2B, 4B, and 6B are too delicate for mechanical drafting but excellent for various artwork types.
a. Hardness of Pencil
| S.N. | Pencil Hardness | Used In Making |
| 1. | 3B to 8B | Artistic and pictorial drawing |
| 2. | H, F, H.B., B, and 2B | All Common Drawing and Writing |
| 3. | 2H to 6H | Technical drawing |
6. Triangular Scales
✔ A tool used to reproduce drawings in regular proportions, either full size, reduced, or enlarged.
7. Erasing Shield
✔This is made of thin metal or plastic with irregular holes. It is helpful to preserve the rest of the drawing while removing smudges, unnecessary pencil lines, and other debris.
8. T-square
✔The T-square is a practical instrument for drawing straight horizontal lines.
It can also assist in producing perpendicular and vertical lines when used alongside set squares.
T-squares are commonly made from wood, plastic, or both materials.
9. Triangles Scales
✔ It is a three-sided ruler, which contains two equal sides intersecting at a 90-degree angle and the third side at 45, 30, and 60-degree angles.
Commonly used triangles are:
a. 30 degrees X 60 degrees
b. 45 degrees X 45 degrees

10. Compass
✔ A compass is a device that can be used for drawing arcs and circles, much like a divider. This device comprises two legs, a pen leg, and a needlepoint leg, connected by a handle.
11. Divider
✔ It is utilized when moving measurements, dividing lines, and arcs into a given number of equal parts.
✔ It can quickly move accurate measurements by adjusting the divider points.
12. Protractor
✔ A protractor is divided into 180 degrees for measuring angles and circles.

13. Drafter
✔ Drafters are used for preparing technical drawings and plans.
✔ Drafter is utilized in making technical drawings to design everything from microchips to skyscrapers.
14. Drawing Table
✔ The drawing table is made up of wood, plastic, or glass and has smooth surfaces where drawing Paper is placed and fixed with the help of tape.
| Designation | Length x Width (mm) | Recommended for use with sheet sizes |
| D0 | 1500 x 1000 | A0 |
| D1 | 1000 x 700 | A1 |
| D2 | 700 x 500 | A2 |
| D3 | 500 x 500 | A3 |

15. Drafting Lamps
✔ Drafting lamps greatly benefits engineers and architects by offering adjustable arms and utilizing fluorescent, halogen, or LED light bulbs.
✔ These lamps enable professionals to work efficiently during the night and easily concentrate on specific areas.
16. Magnifying Glass
✔ A magnifying glass is used to closely watch the small components in the drawing that are less visible to our eyes.
17. Electric Erasers
✔ Using an electric eraser can offer several advantages in accurately removing small lines and borders from drawings.
✔ One of the main benefits is that it can significantly decrease the probability of smudging the drawing paper, thus saving the user considerable time.
18. Blue Print Measuring Tool
✔ Architects and engineers rely on blueprint measuring equipment to streamline their work.
✔ This innovative tool facilitates takeoffs from architectural and engineering drawings, as it can accurately calculate the linear measurements of any shape.
✔ The measuring wheel can be digital, analog, or hybrid and can traverse maps, plans, blueprints, and other flat objects to obtain the necessary dimensions.
19. French Curve
A French curve is a drawing instrument composed of several angles and is commonly made from wood, plastic, or metal.
✔ French curve set ( Burmester set ) commonly consists of 3 curves.
✔ The Bottom Curve is mainly utilized for hyperbolas.
✔ Smaller Curve in the middle is used for ellipses.
✔ Large one Curve is used for parabolas.
