Xu Wen didn't guess Fang Jueming's thoughts at all at this time, he was just looking at the sketches they drew very carefully, comparing them with the real objects in front of them, and estimating where they encountered the problem.

The difficulty is obvious.

On the one hand, it is difficult to see what the structure of the bucket arch looks like from their point of view, and another important reason is that the bucket arch has grooves and overlapping parts, and if this part is not split, it is difficult for them to judge the depth and thickness of this part.

Of course, this is not difficult for Xu Wen at all, and in the modeling diagram in front of him, the structure itself can be split......

"yes, I see. This bucket arch is actually such a form. Xu Wen nodded and directly began to modify the diagram.

Fang Jueming and they were very cautious, and they would rather not do it than mess around.

So although this is a sketch, there are only missing parts, no wrong parts, Xu Wen wants to change, you only need to add to the original parts.

Xu Wen first redrew the entire picture - Fang Jueming drew the oblique side, and what he completed was also the oblique side.

"Huh?" Fang Jueming asked, "How did you judge the thickness of this warp?"

Hearing the word "warp", Xu Wen glanced at Fang Jueming. He remembered that not long ago, when Dilin and the others talked about Dougong, they also mentioned this word.

"Have you studied Damu?" asked Xu Wen.

"Hmm...... I have learned a little fur, but I can only say that it is rubbed. Fang Jueming pursed his lips and said.

"To what extent?" asked Xu.

"Roughly know what it is, what it is used for, what the parts might be called. Fang Jueming said.

This is exactly what Xu Wen lacks.

"Well, I don't know, you can teach me. Xu Wen took it for granted, and he didn't take the secrets of the various families and gangs seriously at all. Of course, this kind of thing is not secretive or anything.

"I didn't measure the thickness of this warp. Then Xu Wen answered Fang Jueming's previous question, "It really can't be measured from this angle, so you see, I drew a dotted line in this part to make a tentative meaning." ”

Fang Jueming nodded suddenly.

"Now I'm going to redraw it, and you'll tell me what the part I drew is called. Xu asked.

Fang Jueming stared at his hand closely, only to see that he turned the paper over first, revealing the back.

The paper provided by the Gyeongeifu is specially made, thick and rough, and the lines are drawn on it with charcoal, which has a bit of a pixel tracing paper. So when I turned over the back, it was blank and not transparent.

Xu Wen first drew two straight lines horizontally and vertically, marked a grid on them, and set the size.

Fang Jueming could see clearly, his pupils shrank slightly, and he secretly clenched his fists.

Xu Wen didn't use a ruler, he just drew two straight lines out of thin air and put some dots on them.

Not to mention that these two lines are drawn extremely straight, it is really like a ruler is drawn, and his points are also just right, every inch apart, and it is really like a ruler is marked.

Fang Jueming is also very sensitive to size, and he is also a good at line fixing, but he asked himself, it is really not easy to do something like Xu Wen without a trace of pyrotechnics.

Xu Wen didn't take this seriously at all, and explained while drawing lines: "I remember that your task requires a scale of eleven, let's set this framework first, and then we can directly use this as a ruler and draw detailed drawings on it." ”

"Hmm. Fang Jueming replied sullenly.

Then, Xu Wen drew the outline of the entire dougong, all of which were dotted lines, but just this one moment made Fang Jueming's eyes light up.

Xu Wen drew very accurately, the basic form of the complete dougong had already appeared in front of his eyes, and some details that they hadn't drawn before were also included, and Fang Jueming felt that this was indeed the case.

"This is the full shape of the side of the big bucket. ”

Fang Jueming remembered what Xu Wen had told him before, and knew that Xu Wen could draw it because of his sensitivity to structure and numbers, that is, the things that taught them every night, in fact, they didn't understand the dougong itself.

He did not have a sense of superiority because of this, but became more and more "awe-inspiring".

Xu Wen didn't understand anything, and he could still draw such a thing, he had learned it to some extent, but he could only take the task to "go through the back door".

He settled down and began to explain to him according to what Xu Wen had said before.

"The old people of Jingying Mansion call this paving, but in fact, it is called Dougong on our Jiangnan Road. The bucket refers to the cushion block, look, it is the shape of the bucket, and it is righteous because of the name. An arch refers to a short piece of wood in the shape of a bow. The one you are painting now is called Ang, and at that time Master said that this was a very important part, but why it was critical, he didn't say. ”

Fang Jueming's voice was light and steady, the enthusiasm in it was real, and the disappointment was real, Xu Wen didn't turn his head, but he was suddenly a little curious, why did a person like him become a monk in the first place, and why did he join the team that went to serve in the Western Desert.

"I don't know what the master thinks, but in my opinion, this ang plays the role of a lever. It uses the role of the inner part of the roof to balance the weight of the outer part of the roof. It's really crucial, it's very ingenious, and I don't know how the earliest masters came up with it. Xu asked.

"What does leverage mean?" Fang Jueming was sure he hadn't heard of the word.

Xu Wen directly picked up the charcoal in his hand and made a demonstration with his fingers.

This principle is very basic, and it is used a lot in daily life, and Fang Jueming can understand it at a glance.

"I see!" Fang Jueming suddenly realized, and repeated the word lever twice in his mouth, feeling that it was indeed very ingenious.

Next, Xu Wen continued to paint, and Fang Jueming continued to explain.

The main thing he could tell Xu Wen was the names of the parts and the words mentioned by the master at the beginning.

The more Xu Wen listened, the more dissatisfied he felt.

The wisdom of the ancient people is really extraordinary, they may have lacked some in some parts, but in others they condensed more to learn.

It's a pity that the master is not here, otherwise even if he is not good at big wood, he must know a lot more than Fang Jueming.

Xu Wen thought with some regret.

Thinking of this, he felt a little embarrassed to dislike Fang Jueming.

However, thanks to Fang Jueming's blessing, he still figured out what the names of the common parts of the dougong were, and it is said that these names will be a little different in different places, but that is only the difference in the name, and the usage is still the same.

With Fang Jueming's explanation, Xu Wen drew the structural diagram of the side of the dougong completely, and marked the size on it.

Some of them were measured by Fang Jueming before, and some of them were tentatively determined by his visual inspection, and he put brackets on this part to distinguish them, Fang Jueming didn't ask what it was, obviously he already knew his habits.

"How to determine the tentative part?" Fang Jueming asked.

"There are two ways, the first one, if it's not convenient to measure here, just measure it in another place. Xu asked.

"We've tried it in a lot of different places!" Xu Wen's words were undoubtedly questioning Fang Jueming's efforts, Fang Jueming frowned, and bluntly expressed his dissatisfaction.

"Where's that bucket arch over there?" Xu Wen was not angry, and pointed to another set of bucket arches on their right front side.

"That ......" Fang Jueming looked in the direction of his finger, and stopped in the middle of his questioning.

Obviously, the dougong that Xu Wen was referring to was the same as the shape they were going to measure, at least there was no difference between him.

"Is that okay, what if they're not the same?" Fang Jueming was still a little unwilling.

"It can't be different. This kind of bucket arch is classified according to type, batch production, fixed-point installation. This is also easier to manage when building. Otherwise, a hall of this scale, could it be that the master craftsman completed it alone?"

Of course it is impossible, ordinary houses have to be built by the master with apprentices, larger houses, and a foreman has to come with many masters, this kind of hall must have its own set of rules, unified standard batch production.

"It's me who wants to fork in. Fang Jueming said embarrassedly, he figured it out instantly, and then found a proof, "There is no sign on the bucket arch over there, and it can be seen that one amount is equivalent to all the quantity." ”

"Yes. Xu Wen affirmed the idea.

"What about the second way?" Fang Jueming found a new way and wanted to do it immediately, but he still remembered what Xu Wen said before, and then asked again.

"The second type, just like Ang, each part of the dougong will have its own role, and there will be no completely useless part. According to its function, we can calculate the interval that can produce an effect, and we can take a mean. ”

"Isn't this a guess, what if it's different from the original?" Fang Jueming asked with a frown.

"It won't be different, the dougong is made, after all, for use. We are now measuring and drawing it, which is also a reference for future use. In this respect, the master builder here should have the same idea as us. Xu asked.

“...... This is also what you teach us every night?" Fang Jueming suddenly asked.

"Yes. Xu asked a brief answer.

"Hmm. Fang Jueming replied softly, thoughtfully.
