What is the importance of design expression (hand drawing and computer drawing)?

Today, with the development and popularization of computer technology and its rapid penetration into various disciplines,

Using the support of various software and hardware technologies provided by computers brings convenience to designers.

Quick drawing operation, convenient to save and modify scheme files,

Not only greatly shortens the design and production time, saves manpower and material resources,

Moreover, many computer-generated design effects can't be achieved by traditional hand-drawn techniques.

This is undoubtedly the revolution of design expression technology and has become the most important expression form adopted in design expression at present.

We can learn from the overwhelming advertisements of various real estate agents.

Especially judging from the bidding schemes of engineering design conducted by various design companies,

At present, the design performance diagram made by computer is simply synonymous with "design performance".

The traditional design expression represented by hand-drawing has been greatly challenged under this mainstream trend.

In order to train talents to meet the market demand, many schools have set up many courses to teach computer drawing software.

There are also many students who specialize in various related computer drawing software at the beginning of their studies.

Even some students have the understanding that hand-painted design techniques are out of date and there is no need to master them.

Many students are very familiar with computer drawing software, but when designing course assignments that require hand-drawn sketches, they are very unfamiliar and unsure.

If conditions permit, you may master both skills, but the reality is often unsatisfactory. Because of time, energy, interest, job requirements and other reasons, you may only be able to master one of them.
