✔ Proper engineering drawing tools are essential for creating high-quality drawings. These tools are commonly used by architects, drafters, engineers, painters, and other technical professionals.

✔ Using drawing tools can significantly improve any artistic creation’s accuracy and final outcome.

✔ Proper drafting tools are crucial for accurate output, whether for artistic or structural drawings. This article will cover the essentials.



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.

Drawing Paper


a. Types of Drawing Paper

Type of Drawing PaperDescriptionSuitable For
Bond PaperHarder and more durable than ordinary papers.Letterheads, Typed reports, Envelopes
Gloss Coated PaperCoated with gloss, it is highly shining in nature.Flyers and Brochures
Matt Coated PaperOpposite of gloss-coated Paper, not shiny.Reports, Flyers, and Leaflets
Recycled PaperMade from recycled paper, it reduces environmental impact.Reports, Memo papers, and Forms
Silk Coated PaperInterim between gloss and matt, smooth coating.Magazines, Books, and Catalogues
Uncoated PaperAbsence of coating, commonly used for official purposes.Forms, Letterheads, Applications writing, Files printing, and Memo paper
Watermarked PaperIt provides a luxury and premium look with a watermark.Documents, Exam Certificates, and Game Certificates


b. Different Sizes of Drawing Paper

Paper SizeDimensions (cm)Paper Area (m2)
A514.8 x 210.03108
A421 x 29.70.0612
A329.7 x 420.125
A242 x 59.40.25
A159.4 x 84.10.50
A084.1 x 118.91


c. Weight of different drawing papers

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 HardnessUsed In Making
1.3B to 8BArtistic and pictorial drawing
2.H, F, H.B., B, and 2BAll Common Drawing and Writing
3.2H to 6HTechnical 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
