• Technical Pens, Pencils, and Leads

• Scales and Compasses

• Erasers and Erasing Shields

• Rulers, Templates, and Curves​

The Perfect Drafting Kit

• Everything has its place.

• Avoid clutter and distractions.

• Promotes focus and efficiency.

​

​Workspace Organization

• used by engineers, architects, and drafters

• specialized in creating lines of uniform thickness.

Use of Drawing Instruments -
Technical Pens

• to create fine, precise lines

• the harder the lead, the lighter and thinner the lines appear and vice versa

Use of Drawing Instruments -
Pencils

Kneaded - Ideal for cleaning and lightening Graphite, Charcoal and Pastels
Vinyl - Ideal on Pencil drawings for detailed and precise cleaning and erasing

Use of Drawing Instruments -
Erasers

Architectural Scales - to draw floor plans and building designs (ft & in)
Metrics does the same as the above scale but uses m and cm.
Engineering Scales - to design things like roads, bridges, or machines

Use of Drawing Instruments -
Erasers

It is a drawing tool that can be used to draw circles or arcs

​

​Use of Drawing Instruments - Compass

It is a drawing tool used to measure angles between two lines, or to draw angles of a certain degree

​

​Use of Drawing Instruments - Protractor

It is a drawing tool that can be used to draw circles or arcs

​

​Use of Drawing Instruments - Set Squares

Architectural Templates - standard drafting symbols cut through them for accurately adding detail to floor pan and elevation view drawings in the scales of 1/16”, 1/8” 3/16”, & ½ inch equal to 1 foot.

​

​Use of Drawing Instruments - Templates

Drawing Templates - enables you to create exact circles, squares, lines, arcs, and more without reaching for a compass, ruler, or protractor.

​

​Use of Drawing Instruments - Templates

• To draw straight horizontal lines on a drafting table.

• Used in conjunction with a set square to draw vertical and angled lines.

​

​Use of Drawing Instruments - T-Squares

• ideal for drawing elipses & irregular curves

​

​Use of Drawing Instruments - French Curves

Conclusion

• The right tools are indispensable in construction drawing.

• An organized workspace boosts efficiency and accuracy.

• Your journey to becoming a skilled draftsman begins here!
