- All seven rooms match the room schedule exactly, 88.56 m² in total, with 3.00 m ceilings. - All 9 doors and 8 windows are where the plan puts them, at the right width, height and sill height. … Two doors don't quite fit where they're drawn: - the door from the hall into Bedroom 2 (D2) - the door from the living room into the dining room (D5) Each is 90 cm wide, but its edge sits 5 cm inside the outside wall, and the drawing shows the same. As drawn, the builder would have to cut into the outside wall, and the door would rub against it when opened. I've modelled both exactly as drawn, with the frame packed out on that side so the door can still open. The fix is easy: move each door 5–10 cm away from the outside wall, or use an 80 cm door. It's best settled before the builder starts.

- 七个房间都与房间表完全一致，总面积 88.56 m²，室内净高 3.00 m。 - 9 扇门和 8 扇窗都在图纸标的位置，宽度、高度和窗台高度都对。 ……有两扇门照图上画的位置放不太下： - 门厅通往卧室 2 的门（D2） - 客厅通往餐厅的门（D5） 两扇门都宽 90 cm，但门边嵌进了外墙 5 cm，图纸上画的也是这样。照图施工的话，施工方得在外墙上凿掉一块，门开的时候还会蹭到墙。 这两扇门我都完全照图建模，只是在那一侧把门框垫出来，让门还能打开。改起来很容易：把门往远离外墙的方向挪 5–10 cm，或者换成 80 cm 宽的门。最好在施工方开工前定下来。

- I checked the whole route by measuring it: it never passes through a wall or furniture, it keeps at least 35 cm clear at body height, and the head turns stay gentle.

中文大意

- 整条路线我都实测过：不会穿过任何墙或家具，在身体高度上始终和周围保持至少 35 cm 的距离，转头也都很平缓。

- Frame 24: it smashes through the red brick cottage. - Frame 58: it knocks down the blue-and-yellow apartment tower. - Frame 90: it plows through the town hall with its turrets and clock tower. - Frame 144: the ball comes to rest on the rubble with its finger holes turned toward camera. - End card: nothing moves after frame 198. Frames 211–240 are a completely still frame: every block, the ball, the camera and the zoom. … - Everything sits in named groups: CAMERA, LIGHTS, BALL, BUILDINGS (one group per building) and ENVIRONMENT. Objects, materials and animations all have readable names, with no leftover defaults. - The timeline has markers on each hit, on "ball at rest", on "all still" and on "end card in".

中文大意

- 第 24 帧：球撞穿红砖小屋。 - 第 58 帧：撞倒蓝黄相间的公寓楼。 - 第 90 帧：碾过带塔楼和钟楼的市政厅。 - 第 144 帧：球停在碎积木上，指孔转向镜头。 - 片尾卡：第 198 帧之后没有任何东西移动。第 211–240 帧是一个完全静止的画面：每块积木、球、相机和变焦都纹丝不动。 …… - 所有东西都放在有名字的组里：CAMERA、LIGHTS、BALL、BUILDINGS（每栋楼一个组）和 ENVIRONMENT。物体、材质和动画都起了好认的名字，没有留下默认名。 - 时间轴上打了标记：每次撞击处，以及“ball at rest”（球停稳）、“all still”（全部静止）和“end card in”（片尾卡进入）处。

Two changes I made Both are invisible in your drawings. As drawn, these parts would pass through each other on every turn: - Leading crank pins: these now stop at the coupling rod's outer face, because that rod is all they carry. At full length they would hit the slide bars and the connecting rod. - Crossheads: the inner face is 40 mm further out than drawn, so the coupling rod passes behind it. The crosshead is hidden behind the cylinder in the front view anyway. Things your members should check - Cylinders: as drawn, they overlap the leading wheel tyres by about 50 mm. I left them alone because their position is clear in both drawings, and the overlap only shows from underneath. A related 5 mm overlap between the connecting rod and the lower slide bar can't be seen at all. - Coupling hooks: the SVG draws these pointing downwards, and I kept that. Real drawhooks usually point up. - Smokebox door: I've hinged it on the right as you face the front, which is the engine's left. That's the way the hinge straps run in your drawing.

我做的两处改动 这两处在你们的图纸上都看不出来。按图纸原样，下面这些零件每转一圈都会互相穿过： - 前轮曲柄销：现在只伸到连杆的外侧面为止，因为它们只带这一根连杆。保持原长的话，会撞上滑杆和主连杆。 - 十字头：内侧面比图纸往外移了 40 mm，这样连杆就从它后面过去。在正视图里，十字头本来就被汽缸挡着。 请会员们核对的地方 - 汽缸：按图纸，汽缸和前轮轮箍重叠约 50 mm。我没有动它们，因为两张图纸都把汽缸位置标得很清楚，而且这处重叠只有从下面才看得到。与此相关，主连杆和下滑杆之间还有 5 mm 的重叠，从外面根本看不到。 - 车钩：SVG 里车钩画成钩尖朝下，我照图保留了。真实的牵引钩一般朝上。 - 烟箱门：我把铰链装在面朝车头时的右侧，也就是机车自身的左侧。你们图纸上的铰链板就是这样走的。

Two readings of the brief to confirm: 1. Black finish. The brief names only the frame for black, so I made Black a third complete sideboard with a black-stained body and put the black frame under all three. If you meant oak and walnut bodies sharing one black frame, with Black holding just the frame, say so; it is a small change. 2. Depth. The carcass is 420 mm deep. The fronts sit 24 mm back and the handles project 22 mm, so nothing passes 420.

中文大意

有两处对需求的理解请您确认： 1. 黑色饰面。需求里黑色只提到了框架，所以我把 Black 做成第三套完整的边柜，柜体用黑色染色木，三套下面都是黑色框架。如果您的意思是橡木和胡桃木柜体共用一个黑色框架、Black 里只放框架，请告诉我，这只是个小改动。 2. 深度。柜体深 420 mm。门板和抽屉面板往里缩了 24 mm，拉手凸出 22 mm，所以没有任何部分超出 420。

Oak, Walnut and Black are unchanged. I added to the approved file instead of rebuilding it, and a comparison against that file shows the three collections identical. … 1. Body. Your request names only the frame, so I put it on the oak body. If Sales want it on walnut instead, that is a material swap; if they want it on walnut as well, that would be a further collection. 2. Handles. I left them black for the same reason. Say if they should match the frame. …

中文大意

Oak、Walnut 和 Black 都没有改动。我是在已确认的文件上添加，没有重新搭建；和那个文件比对，三个集合完全一致。 …… 1. 柜体。您的需求只提到了框架，所以我把它配在橡木柜体上。如果销售想配胡桃木柜体，换个材质就行；如果两种都要，就再加一个集合。 2. 拉手。出于同样的原因，拉手我保留了黑色。如果要和框架同色，请告诉我。 ……

- Belts belong to the posts. Each belt is drawn by a modifier on the post it starts from, so belt pixels are labelled as that stanchion. When you move a post, the belts attached to it follow; I tested this. … - Screens: the wall displays, locker terminal, staff monitors and card terminals are all matte, non-glowing dark panels. The monitors and card terminals are part of counter_01. - What glows: only the light panels, the frosted windows, and the exit sign sign_06. The exit sign shows a door outline and an arrow, not a running man. - Sign text: the counter signs show the numbers 1–4. Other signs use only arrows and simple icons, with no people. Each labelled object has class and instance properties and its own object index, and the object-index render pass is turned on. …

- 伸缩带算在立柱名下。每条伸缩带由它起点那根立柱上的修改器生成，所以伸缩带的像素会标成那根 stanchion。挪动一根立柱时，连在它上面的伸缩带会跟着走；这一点我测试过。…… - 屏幕：墙面显示屏、快递柜终端、员工显示器和刷卡机都是哑光、不发光的黑色面板。显示器和刷卡机属于 counter_01。 - 会发光的：只有灯板、磨砂窗和出口标识 sign_06。出口标识画的是门框轮廓加箭头，不是奔跑的小人。 - 标识文字：柜台标识只显示数字 1–4。其他标识只用箭头和简单图标，没有人。 每个带标签的物体都有 class 和 instance 两个属性和各自的物体索引，物体索引渲染通道也已打开。……

Why it was so heavy: two chairs, the espresso machine, the counter and one plate were simple flat shapes that had been subdivided over and over, adding up to 256 times the faces without changing the shape. I collapsed them back to their clean form, so the geometry is identical. The grinder had a subdivision modifier at level 4 (43k tris). I baked it in at level 2 (2.7k tris), which is within 1 mm of the original. It needed baking anyway: the glTF exporter doesn't apply modifiers by default, so the viewer would have received the blocky unsmoothed shape. Doubled up: five objects had an exact copy stacked in the same spot (floor lamp, menu board, a chair, a cup, a saucer). I deleted the extra copy of each. … Things I fixed that you didn't ask for: - One saucer and one cup were inside-out. They would show up dark or invisible in a web viewer. … How I checked: I rendered from the camera before and after. With the floating fixes temporarily undone, the two renders match almost exactly: no pixel differs by more than 15/255, and only 9 differ noticeably at all. The camera itself is untouched. I also loaded the saved file in a separate Blender to recheck every requirement, and a test GLB export came out at 8,006 tris and 12 materials (395 KB).

为什么这么重：两把椅子、意式咖啡机、柜台和一个盘子都是由平面围成的简单形体，却被一遍又一遍地细分，面数加起来翻到原来的 256 倍，形状却丝毫没变。我把它们还原成干净的原始形状，几何完全一样。磨豆机上挂着一个 4 级细分修改器（4.3 万个三角面）。我按 2 级把它烘焙进网格（2,700 个三角面），和原来相差不到 1 mm。反正它也得烘焙：glTF 导出器默认不应用修改器，查看器收到的会是没经过平滑、棱角分明的粗糙形状。 重复叠放：有五个物体在同一位置叠着一个一模一样的副本（落地灯、菜单板、一把椅子、一个杯子、一个碟子）。每组多出来的那一个我都删掉了。 …… 你没要求、我顺手修好的： - 有一个碟子和一个杯子里外翻了。放到网页查看器里，它们会发黑，甚至看不见。 …… 我是怎么核对的：我从相机分别渲染了修改前后的画面。把悬空修正临时撤销后，两张渲染图几乎完全一致：没有一个像素的差值超过 15/255，有明显差别的像素只有 9 个。相机本身没动过。我还在另一个 Blender 里打开保存好的文件，把每项要求重新核对了一遍；试导出的 GLB 是 8,006 个三角面、12 种材质（395 KB）。

To check the loop, I rendered all 180 frames at low resolution: the jump from the last frame back to the first can't be told apart from any other frame step, and there's no flicker anywhere in the sequence. … - Your logo's ring is open in the middle, so to stick to just your two colours I made the face inside the ring brown. The background is plain #E9B949. … - Brown face (front-on): about (107, 66, 40) against #6B4226's (107, 66, 38). - Gold wheat: about (235, 184, 70) against #E9B949's (233, 185, 73). … - Frame 180 is 2° short of a full turn, so going back to frame 1 is the same 2° step as every other frame.

中文大意

为了检查循环，我用低分辨率把 180 帧全部渲染了一遍：从最后一帧跳回第一帧，和其他任何相邻两帧之间的变化分不出差别，整段序列里也没有任何闪烁。 …… - 你的 logo 圆环中间是空的，为了只用你给的两种颜色，我把圆环里面的盘面做成了棕色。背景是纯色 #E9B949。 …… - 棕色盘面（正对镜头时）：约 (107, 66, 40)，对照 #6B4226 的 (107, 66, 38)。 - 金色麦穗：约 (235, 184, 70)，对照 #E9B949 的 (233, 185, 73)。 …… - 第 180 帧离整圈还差 2°，所以从它回到第 1 帧，和其他每一步一样，都是转 2°。

- Legs: they use IK with knee targets and stretching turned off. When the body lowers, the goat's front knees bend forward, its hind hocks bend back and the goose's ankles fold back. The feet stay planted and the leg bones don't change length. - Idle loops: frames 0–48 at 24 fps, which is exactly 2.0 s. Frame 48 is the same pose as frame 0, with zero difference in the mesh. - Both: breathing (the belly swells and the body settles a few mm, which flexes the knees) and a small head turn with a tilt. - Goat: a tail twitch. - Goose: a quick wing twitch. … Extras I added: small ear flicks on the goat and a little tail wag on the goose. They're separate keys, easy to delete if you don't want them.

- 腿：用 IK 控制，带膝盖朝向目标，关闭了拉伸。身体下沉时，山羊的前膝向前弯，后腿跗关节向后弯，鹅的踝关节向后折。脚始终踩在原地，腿骨长度不变。 - 待机循环：第 0–48 帧，24 fps，正好 2.0 秒。第 48 帧和第 0 帧姿势相同，网格上没有任何差别。 - 两只都有：呼吸（肚子鼓起，身体下沉几毫米，膝盖随之微屈），以及小幅转头并略微歪头。 - 山羊：甩一下尾巴。 - 鹅：快速抖一下翅膀。 …… 我额外加了：山羊耳朵的轻微抖动，鹅尾巴的小幅摆动。它们是单独的关键帧，不想要的话很容易删掉。

All eight props are under 800 tris, with one UV map each and the pivot at the base. I reopened the saved file to confirm, and test exports to glTF and FBX worked (temporary files, since deleted). … Quay tiling: the quay is 6 m long and 3 m deep, with the deck surface 2.5 m above its pivot. Placing copies every 6 m along X gives seamless joins; the coping joints and fenders stay evenly spaced across the seams. I checked this with three tiles side by side. … Every prop shares one material, M_Harbour_Palette, which reads its colours from one small texture of flat colour swatches (T_Harbour_Palette.png). Each face's UVs point at its colour's swatch, so you recolour by repainting a swatch. The texture is packed into the .blend and also saved next to it. The only second material is M_Harbour_LampGlow, an emissive one used just for the lamp glass on the lamp post and the office door lamp.

中文大意

八件道具都在 800 个三角面以内，每件一套 UV，原点在底部。我重新打开保存好的文件确认过，导出 glTF 和 FBX 的测试也都成功（临时文件，已删除）。 …… 岸壁拼接：岸壁长 6 m、进深 3 m，台面比原点高 2.5 m。沿 X 轴每隔 6 m 放一段就能无缝拼接，接缝两侧的压顶石缝和护舷间距保持均匀。我把三段并排放在一起检查过。 …… 所有道具共用一个材质 M_Harbour_Palette，颜色取自一张由纯色色块组成的小贴图（T_Harbour_Palette.png）。每个面的 UV 都指向它那种颜色的色块，所以重涂某个色块就能改色。 贴图已打包进 .blend，也另存了一份在它旁边。 另外只有一个材质 M_Harbour_LampGlow，是自发光材质，只用在路灯的灯罩玻璃和港务小屋门口那盏灯上。

The bin is now 56.0 mm tall overall, lip included, which leaves 2.0 mm under your 58 mm drawer. It's still 2×4 with 2 dividers. The footprint, lip shape, feet and magnet holes are unchanged; the lip just sits lower. What changed - New setting: the Size panel now has a Custom Overall Height toggle and an Overall Height value in mm, lip included. It's switched on at 56 mm and used instead of the 7 mm units. - Interior: the lip now starts at 51.6 mm. The 3 compartments are still 54.2 × 81.1 mm, but now 44.6 mm deep instead of 49. The dividers still stop 1 mm below the lip. - Other bins for this drawer: if you make them by duplicating this one (Shift+D), they keep the 56 mm setting. Change only width, depth and dividers.

盒子现在含唇边总高 56.0 mm，放进 58 mm 的抽屉还剩 2.0 mm。仍是 2×4、2 道隔板。占地尺寸、唇边形状、支脚和磁铁孔都没变，只是唇边整体下移了。 改动 - 新设置：Size 面板里新增了 Custom Overall Height 开关和 Overall Height 数值（单位 mm，含唇边）。开关已打开，设为 56 mm，取代按 7 mm 单位算的高度。 - 内部：唇边现在从 51.6 mm 处开始。3 个格子仍是 54.2 × 81.1 mm，深度从 49 mm 变为 44.6 mm。隔板仍比唇边低 1 mm。 - 这个抽屉的其他盒子：如果复制这个盒子来做（Shift+D），会沿用 56 mm 的设置，只需改宽、深和隔板。
