Summary

In this video, Putri introduces viewers to the basics of technical drawing, focusing on conventional tools and techniques. She explains how to correctly place drawing paper on a drawing board, the proper use of pencils and mechanical pencils, and the importance of selecting the right tools based on the type of lines being drawn. Additionally, she demonstrates how to use rulers, triangular rulers, and compasses for precise line and circle creation. Finally, she shares tips on setting up a drawing workspace to improve comfort and accuracy, all aimed at helping beginners get started with technical drawing.

Takeaways

• 😀 Always place the drawing paper on a smooth and flat surface, closer to the left and bottom of the drawing board to avoid misalignment.
• 😀 Drawing paper can be placed in either landscape or portrait orientation depending on the requirement.
• 😀 Use removable adhesive tape to keep the paper in place, ensuring it doesn’t shift and cause inaccuracies.
• 😀 Select the appropriate pencil type based on the paper and the kind of line you want to create.
• 😀 For pencil drawing, keep the pencil rod at an angle of 60°-85° and rotate it using your thumb and index finger for even lines.
• 😀 If using a mechanical pencil, ensure the pencil lead matches the type of line you want to create and hold the pencil perpendicular to the drawing plane.
• 😀 Use a T-ruler, which can be moved up and down with a consistent slope, for straight lines and accurate measurements.
• 😀 A pair of triangular rulers can be used in conjunction with a C-ruler to create various types of lines, such as vertical, horizontal, or diagonal.
• 😀 When using a compass, make sure it’s perpendicular to the drawing surface to produce a circle with even thickness.
• 😀 To create curved lines, use a curved mall and connect at least three points to guide the curve’s shape.
• 😀 For home setups, any flat and smooth surface can be used as a drawing board, but it’s beneficial if the board is slightly slanted for better comfort during the drawing process.

Q & A

What is the first step in placing the drawing paper on the drawing board?

The first step is to choose a drawing board with a smooth and flat surface.

Where should the drawing paper be placed on the drawing board?

The drawing paper should be placed closer to the left and the bottom of the drawing board.

What are the two orientations for placing the drawing paper?

The two orientations are landscape and portrait.

How can you prevent the drawing paper from shifting on the drawing board?

To prevent the drawing paper from shifting, you should use adhesive tape that is easy to remove, ensuring the paper stays in place.

What should be done to maintain the condition of the drawing paper?

Make sure that the drawing paper is always clean and dry before starting the drawing process.

What is the correct way to hold and use a pencil for technical drawing?

When using a pencil, it should be tilted at an angle of 60 to 85 degrees. The pencil should be rotated using the thumb and index finger in a clockwise direction to ensure an even line.

How should the pencil lead be prepared for use?

The pencil lead should be extended to about 25 mm, with approximately 10 mm of the lead visible for drawing.

What is the proper technique for using a mechanical pencil in technical drawing?

When using a mechanical pencil, ensure the pencil lead size is appropriate for the type of line to be drawn. The pencil should be held perpendicular to the drawing plane.

How does the T-ruler assist in technical drawing?

The T-ruler, which has a retaining rod, is attached to one side of the drawing table, allowing it to be moved up and down at a consistent slope, aiding in precise line drawing.

How can you use a pair of triangular rulers in combination with a C-ruler?

A pair of triangular rulers can be combined with a C-ruler to make vertical lines or to draw lines with various slopes, providing more flexibility in technical drawing.

What is the purpose of a compass in technical drawing?

A compass is used to draw circles with even thickness and should be held perpendicular to the drawing plane for accurate results.

What method is used to create curved lines that are not part of a circle?

To create non-circular curved lines, at least three points are used to guide the curvature, ensuring the line matches the desired shape.

What are the key features of an ideal drawing table or drawing board?

The drawing table or board should have a flat and smooth surface, and it’s preferable to have a slanted position at the top and lower at the bottom to reduce fatigue and make the drawing process easier.
