The diamond under the projector is two carats. The six projection surfaces exaggerated by the projector are so beautiful that people want to bow and worship.

"It's beautiful!" Yan Juan couldn't help but sigh softly.

"Otherwise, how can you attract so many people to spend a lot of money?" The students around me also sighed, "If I have money, I want to buy it too." ”

"The cut of this diamond is perfect, every angle is calculated precisely, and there should be room for appreciation if it is collected." Yan Juan had an occupational illness, and after finishing speaking, he apologized abruptly, "I'm sorry, I habitually treat you as a customer." ”

The other party smiled dumbly: "You said it very professionally, are you at the diamond counter?" ”

"yes, what about you?"

"My name is Tian Momo, and I am a cutter, but I am an intern, so now I am only cutting some low-grade gemstones, and the most are crystals."

"O cutter!" Yan Juan immediately poured, "There aren't many women who are cutters, right?" ”

"It's okay, it's not a rare animal. Hey, you say, if you buy diamonds, how big should you buy? The other party seemed to have a soft spot for diamonds, so he grabbed Yan Juan and asked.

"Diamonds above 0.5 carats and under 2 carats are best."

"Why?"

"It's hard to get a diamond that's too small, and it's hard to sell a diamond that's too big. So, if you just wait for appreciation as a collection, I personally think this range is the most suitable. "Generally speaking, those with a score of less than 24 are generally called small diamonds or broken diamonds, and there is no room for appreciation at all. 25 to 99 points is a medium diamond, more than one carat, even a big diamond. ”

"If it's more than 1 carat, it must be expensive, right?" Tian Momo obviously has an ordinary family background, and he only dares to think about big diamonds.

"It depends on the clarity, the special diamond ring launched by our store celebration this time is a little more than one carat, and there is a little flaw in the clarity, and the price is not expensive, a little more than 30,000."

"Oh." Tian Momo wanted to ask again, but Pang Zhengde coughed twice, and the two of them could only silence and listen to the explanation.

"Of course, the structure and shape of most jewelry pieces are still relatively simple, and most of them are symmetrical, so we can use a simplified three-projection surface system and the corresponding three views, that is, the main view, the left view and the top view, or even only two views, the main view and the top view. In this lesson, we will learn the system of three views. ”

As if playing a trick, he took out another ring: "Let's go from easy to difficult, let's start with the easy ones." The ring has a symmetrical and simple shape, just draw a three-view view. In addition, I would like to emphasize that our jewelry design uses the focal perspective method, which is different from the scattered perspective method used in Chinese paintings, which needs to fix the point of view in a certain position. ”

"Sounds simple...... Tian Momo muttered, and immediately lowered her head and drew on the manuscript paper.

Yan Juan was not in a hurry to start writing, and observed for another ten minutes before the pen flew like a fly.

This time, it is much smoother than the pen power in the previous class. Yan Juan felt that after painting a few more times, all the previous feelings would come back. I only felt that with a few brushstrokes, the three views of the ring jumped on the paper.

Unable to get enough of it, she drew another rendering of the ring.

"Good." Pang Zhengde patrolled in front of the student's desk, and when he walked to Yan Juan's side, he happened to see her put away the pen, and immediately praised her without hesitation, picked up her manuscript paper, and walked to the podium.

"The painting of the Yan Juan student is quite outstanding. The size is well grasped, and the projection part is added to the renderings, which makes it more vivid and three-dimensional. You can pass it on as a model. ”

Yan Juan was a little embarrassed, turned her head to the side, but saw Tian Momo give her a thumbs up: "It's really good." ”

"I studied sketching for ten years as a child." Yan Juan explained in a low voice.

"No wonder, it turns out that art is connected!" Tian Momo choked, "It's a pity that I didn't learn anything when I was a child, my parents always wanted me to grow up naturally, and as a result, I grew into a weed." ”

Yan Wanwan smiled: "Are weeds bad?" What a happy childhood! ”

"That's right, I was raised by my parents to be a wild boy." Tian Momo laughed under her voice and made a grimace. I happened to see Pang Zhengde's face turned around, and he hurriedly sat upright, looking serious about revising the sketch.

"Your drawings are good, but a good designer is not only about drawing renderings, but also about making some beautiful drawings. The ultimate goal of the design is to be completed only after the selection and processing of materials to make the samples or products of the expected style. Designers also need to be familiar with the workability of various gemstones, as well as the cost of materials and processing expenses. ”

Yan Juan was humbly taught, and nodded again and again: "Design is a dynamic species, not just a piece of paper, right?" It is not a category of pure art, it is only a pattern modeling, and it does not represent plasticity. Teacher, I understand, I don't know, right? ”

"Not bad." Pang Zhengde looked happy with the "teachable" look, obviously very satisfied with Yan Juan's comprehension, "However, you have such a good foundation in painting, you can be handy when drawing drawings." ”

"Thank you, teacher." Yan Juan smiled at Pang Zhengde gratefully, "I think I learned a lot in the training class. ”

"I just want to teach you everything I know." Pang Zhengde sighed, and there seemed to be some kind of pain in his eyes. Yan Juan couldn't help but guess that maybe he also had some unknown hidden pain.

The homework was handed over to the podium one after another, and Pang Zhengde walked back: "Okay, that's all for today's class." I'm going to give you today's homework and design a ring that everyone is free to do, regardless of the material of the gemstone. Before class tomorrow, I hope to be able to see everyone's homework. ”

"Designing so soon?" The students were somewhat excited.

After taking classes for more than half a year, I finally really touched the level of design. Therefore, when everyone rushed out of the classroom, they were more or less excited.

Yan Juan felt a little dazed, so when he was packing his things, he hesitated. I wanted to ask Pang Zhengde, but I felt that it was late at night and disturbed his rest time, so I was embarrassed.

"Yan Xuan." Pang Zhengde stood at the door with a lesson plan.

"Yes, Teacher." Yan Juan hurriedly agreed.

"As for the concept of design, I talked about it last semester, and you have a good understanding, I will probably mention it, and you should understand."

Yan Juan suddenly perked up: "Teacher, please speak." ”
