If you want to wait for the CAD class to start teaching at school, you have to wait at least until after the major is divided, that is, the second year of college.

Huang Shouzhen can't remember when he first came into contact with CAD, but he remembers that the CAD course taught in school is very simple, only a short four-week course, so he is basically familiar with this software, and then simply draws a few irregular graphics as homework, and it is over again.

However, in the case of universities, there are only a few courses in each major, so students can understand the content, and if they really want to turn the content into vocational skills and put them into work, everyone will be re-taught by a regular company outside the school.

"We drew a complete set of construction drawings, mainly including three parts: plane system drawing, elevation drawing, and section drawing.

Among them, in the plane system diagram, it can be subdivided into three levels: plane, ceiling and ground......

The elevation drawing relies on the index drawing in the plane system diagram to draw all the faces of each independent space.

A simple example is these four walls in our dormitory!

As for the section drawing, it is a node detail used for process production, which will be relatively complex, and if the modeling in the detail drawing is too complex and a drawing cannot be placed, then we need to continue to enlarge some parts of the section drawing, which is called a large sample drawing!"

Huang Shouzhen went through the construction drawings with Xu Fan one by one according to the construction drawings he had drawn by himself, so that they had an idea in their hearts, and then continued: "Of course, you are now zero-based, you can temporarily put aside this part of the section drawing, first master the plane system diagram and elevation drawing, and then slowly deepen and understand the process, do you understand?"

Got it?

Understand, what a ghost!

Xu Fan and the three of them standing behind him were all confused, and they only felt that there seemed to be too much to learn in the future.

This guy is so perverted that he secretly learned so many skills without my knowledge?

When exactly did he learn?

Ye Haiwen looked at Huang Shouzhen like a monster, and felt more and more that the latter was full of unexplained mystery.

"Ah Zhen, are these drawings you just showed us just the drawings that need to be used in a house?" Ye Haiwen thought about it, and still raised the question in his heart.

Huang Shouzhen said truthfully: "Yes, the drawing you see now is the complete version of the construction drawing of the project I did during the summer vacation!"

"Grass, this is too much, right? I just roughly counted, I'm afraid there must be forty or fifty drawings in this set, right? Are you sure I can learn them in half a year?" Ye Haiwen received Huang Shouzhen's exact answer, his face suddenly darkened, and he felt a little stressed inexplicably, "You shouldn't be fooling me, right?"

Huang Shouzhen saw that the other party seemed to have the intention of retreating, and he was speechless for a while.

What the hell is this guy doing, run away first!

So, after thinking about it, he replied: "Lao Ye, how easy it is for you to look at the drawings, don't just look at the quantity?"

Take the floor plan diagram as an example, in addition to the floor plan and ceiling modeling, which are a little more difficult, like other furniture size drawings and ceiling shape size drawings, isn't it just to mark a size?

What can be the difficulty?

As for the elevation, it's even simpler, you just need to draw the shape directly according to the appearance of the renderings, and then mark them with dimensions and materials.

I might as well tell you, as long as you can draw a complete set of drawings, from now on, you will be comfortable in the drawing of construction drawings, what is there to be nervous about?"

Immediately, Huang Shouzhen saw that Ye Haiwen was too afraid to refute what he said, so he softened his tone, and then said in a serious, soft and hard manner: "Old Ye, construction drawings are very rigid things, as long as you are willing to spend more time practicing, let alone half a year, three months, I guarantee that the floor plan and elevation drawing, you have already practiced."

The most important thing is that even if you don't understand it now, don't I have a set of ready-made drawings here?

You can take it and print it out and refer to the painting, right?"

Ye Haiwen was completely speechless, and was silently spoken by Huang Shouzhen, but he was secretly slandering himself in his heart...... You said it lightly, you yourself have learned it early, of course you don't find it difficult......

And what's going on with your tone?

It sounds like a teacher of various subjects, full of simple questions and simple questions......

At this moment, Ye Haiwen no longer admired Huang Shouzhen, but had deep doubts, because he always felt that the latter seemed to be fooling himself!

Xu Fan and Chen Lei, who were next to him, did not speak during the period, until Ye Haiwen was speechless by Huang Shouzhen, and the former spoke: "Shouzhen, you just said these things, it feels too late, we don't even know how to use this software now, how can we draw drawings?"

Huang Shouzhen heard Xu Fan say this, and replied with a slight smile: "That's why I said, if you really want to learn interior design, at least you have to have a computer first, drawing requires you to spend a lot of time to practice and accumulate, and there is no shortcut." ”

When Xu Fan heard this, he couldn't help but fall into silence.

Chen Lei next to him asked Huang Shouzhen, "So you mean let's hurry up and buy a computer?"

Huang Shouzhen said bluntly: "Yes, if you want to work early, make money, and then support yourself, buy a computer as soon as possible to learn these basic knowledge, and you will learn it in the future anyway, right?"

Chen Lei nodded and replied: "That's right, then I'll call my dad later, and ask him to remit some euros to buy me a computer, but it's ......."

"But what?"

"But why did you only call me and Xu Fan to listen to the class, aren't you going to teach Junjie them?"

Huang Shouzhen heard Chen Lei ask this, he knew that Luo Junjie and those guys would not take the road of interior design in the future, of course, he would not waste this idle effort, so he said angrily: "I'm not a teacher, I'm already the limit for teaching the three of you, okay, you treat me as a fairy?"

Besides, I'm teaching you these things now, but it's free, and it's good that I didn't charge you tuition separately!"

Chen Lei: "......"

After a while, Huang Shouzhen saw that Chen Lei and Xu Fan were silent, so he said to Ye Haiwen again: "Okay, what I want to talk about today, that's about it, the next time is for Lao Ye, you can demonstrate what you learned last week to them on my computer, and by the way, you will review it yourself." ”

When Ye Haiwen heard this request, he was stunned.

"This ...... But I only know how to use shortcuts now, so why don't you teach them yourself?"

When Huang Shouzhen heard Ye Haiwen say this, he immediately glanced at the latter, and then said sarcastically: "I want me to come to everything, and then everyone will make money together, can I also spend it alone?"
