It is mainly used for artistic sketching and drawing, for stenography or notes. Its benefits are the simple usage as well as being able to remove what you've drawn with an eraser. What makes the pencil a writing utensil is based on the crystal structure of the graphite and a low Van der Waals force.
It contains a protractor, time-minute scales used for adding marks every minute along the track, time-in-turn scales for doing the same in turns at various bank angles and air speeds, a nautical mile scale for distances, a 1000 meter grid for plotting exact coordinates on a 1:250 000 scale map and some figures used for various annotations on the map
Efficient to Use - Draw horizontal and vertical parallel lines with ease. Also allows for easy drawing of circles, curves, or arcs.
Drafting brush: a hand brush used to sweep away debris from a drawing to prevent smearing.
The drafting machine, introduced about 1930, allows a straightedge to be moved while maintaining any desired angle between it and the edge of the drawing board. Combining the functions of the T square, triangle, protractor, and scale, it greatly increases the efficiency of producing a drawing.
Electrical, HVAC, and design planning templates are used to create mechanical or architectural drawings via pre-cut holes and guidelines. They make it easy to draw or measure precise shapes and lines repeatedly and consistently
A ruling pen is a drawing instrument for drawing with ink or with other drawing fluids. Originally used for technical drawings in engineering and cartography together with straight rulers and French curves, it is today used for specific uses, such as picture framing or calligraphy.
What is a drawing tube used for? A drawing tube can be used for storing maps, artwork, posters, blueprints, and other large-format documents. It can protect them from folds, tears, and other exterior elements while also making it easier to move them from one place to another.
Mechanical pencils are used to provide lines of constant width, without need of sharpening, for tasks such as technical drawing as well as for clean looking writing. They are also used for fine-art drawing. Since they do not have to be sharpened, they are also popular with students.
Used for position plotting on small scale charts (such as weather maps), converting seconds scale on a chart to decimal minutes, interpolating depth contours on charts and many other applications.
for Geometry, Drawing, Drafting, measuring precise distances between two points and drawing arcs.
