Q & A

What are the different types of paper commonly used in technical drawing?

The common types of paper used in technical drawing include Padalarang paper, tracing paper, and white HVS paper. White HVS paper is typically used in technical drawings, and it comes in various sizes such as A0, A1, A2, A3, and A4.

How are the different sizes of paper measured in technical drawing?

The sizes of paper are measured in millimeters, with A0 being the largest size. For example, A0 measures 841x1189 mm, and A1 is 594x841 mm. The sizes are halved as you go down the series (A0, A1, A2, etc.).

What are the two types of pencils used in technical drawing?

There are two main types of pencils used in technical drawing: manual pencils, which are commonly used in daily life, and mechanical pencils, which can be refilled with lead.

What are the different levels of hardness for pencils used in technical drawing?

Pencils used in technical drawing have three levels of hardness: hard, soft, and very soft. The hardness scale includes grades such as H (hard), B (soft), and varying numbers indicating the degree of hardness or softness (e.g., 2H, 7B).

What is the purpose of a rapido pen in technical drawing?

A rapido pen is used for making lines in technical drawings. It has replaceable tips in different sizes and functions similarly to a pencil but is used for more permanent and precise line work.

How is an eraser used in technical drawing?

An eraser in technical drawing is used to remove unwanted lines, letters, numbers, or markings from the drawing. It helps correct mistakes made during the drawing process.

What is the primary function of a compass in technical drawing?

A compass is primarily used to draw circles. However, it can also be used to divide angles, divide lines, and create other geometric shapes or constructions.

What are the types of rulers commonly used in technical drawing?

Common rulers used in technical drawing include the triangle ruler, which has special angles of 30°, 45°, 60°, and 90°, as well as other rulers like the crystallizer and scale rulers, which are used for measurement and drawing at specific scales.

How is a protractor used in technical drawing?

A protractor is used to measure angles. For example, it can be used to measure a line at a specific angle like 45°, which is common in certain drawings.

What is the role of a drawing table in technical drawing?

A drawing table provides a smooth surface for drawing and must be larger than the drawing paper to accommodate various paper sizes. If a drawing table is unavailable, other smooth surfaces can be used as a replacement.
