Have you ever heard of graphite paper? Is that ancient times?
With the development of modern technology and computers, we have become Xi to use computer-aided design (CAD) software to draw drawings, but have you ever wondered how designers drew drawings before the invention of CAD?
Let's go back in time and see how designers went through hardships and creativity before the advent of CAD.
Before the 20th century, designers relied mainly on paper, pencil and ruler to draw pictures. At that time, paper drawings were an indispensable working material, and graphite paper was an important auxiliary tool.
Before starting the drawing, the designer needs to make careful measurements and planning. They use a ruler to measure various sizes and accurately mark them on paper.
Next, the designer holds a pencil in his hand and laboriously sketches the outline of the design. They need a steady hand and good eyesight to ensure precise and smooth lines.
Graphite paper, on the other hand, is an important tool for copying and transmitting drawings. The designer places the graphite paper on the original drawing and presses it on it with a pencil so that the ink on the graphite paper can be transferred to the new paper, thus making an exact copy of the drawing.
This process of drawing takes a lot of time and effort. Once a mistake is made, the designer needs to start over or use an eraser to correct the mistake, which undoubtedly increases the difficulty and complexity of the work.
In addition, careful care is required when drawing complex shapes to ensure that each line is accurately depicted.
Fortunately, technological developments don't stop there. In the mid-20th century, the advent of computer-aided design (CAD) software revolutionized the way designers worked.
Today, designers can rely on CAD software to quickly draw complex drawings, accurately calculate dimensions and angles, and easily modify and adjust designs. This not only greatly improves work efficiency, but also reduces the possibility of errors.
Through CAD software, designers can view 3D models in real time and display them with three-dimensional and realistic display, so as to better understand and communicate their design ideas.
To sum up, we can't help but marvel at the convenience that the advancement of technology has brought to designers. While CAD software has become the standard in the design industry, we should also remember the designers of the past who relied on hand drawing and creativity to create countless stunning designs without modern tools.
It is because of their hard work and dedication that today's CAD technology makes it easier for designers to realize their ideas and dreams.
Future designers will continue to innovate driven by technology, and we are looking forward to their exploration!
So, when you use CAD software, remember that this is only part of the long creative journey of designers, and we should cherish and celebrate the convenience brought by technology and the hard work behind it.
