从模型排版到 CAD 交付，二维出图流程全面就绪 From model layout to CAD delivery, a complete 2D documentation workflow

拍图1 · 模型排版Drawing 1 · Model Layout

从有效的 Rhino 引用模型中筛选、自然排序和去重，并按模号分组排格。可输出排格模型、矩形框和模号文字，结果可直接传给“拍图2 · 生成图纸”。排格设置与分类输出选择会随 Grasshopper 文件保存。 Filters, naturally sorts, de-duplicates, groups, and lays out valid referenced Rhino models by model number. Optional outputs include arranged models, frames, and model-number text. The result connects directly to “Drawing 2 · Generate Drawings,” while layout and category-output settings are saved with the Grasshopper file.

拍图2 · 生成图纸Drawing 2 · Generate Drawings

仅在点击“开始运算”后执行 Make2D，普通连线、上游变化或应用设置不会触发重算。组件支持循环分批处理、进度显示和停止请求；只有全部完成后才向下游发布完整结果。剖面、轮廓标注、角度标注、转置模型及多类图层输出均可独立控制。 Runs Make2D only after “Start Calculation” is clicked; wiring, upstream changes, and applying settings do not trigger recalculation. It supports batched processing, progress reporting, and stop requests, and publishes a downstream result only after the complete job finishes. Sections, outline dimensions, angular dimensions, transposed models, and categorized layer outputs can be controlled independently.

完整结果可保存为缓存并在重新打开文件后恢复预览、分类输出及 CAD 导出数据。恢复结果会明确标记为历史结果；旧缓存格式或 Rhino 主版本不一致时不会载入。恢复缓存不包含原始图框 DWG，后续导出仍需保留模板文件。 Completed results can be cached and restored after reopening the file, including previews, category outputs, and CAD-export data. Restored data is clearly identified as historical; older cache formats or a different Rhino major version are not loaded. The original border DWG is not stored in the cache and remains required for later export.

拍图3 · 导出 CADDrawing 3 · Export CAD

直接使用第二步最近一次完整结果导出，不会重新运行 Make2D。可将模型编号及其加工编号分别映射到图框中真实存在的属性 Key，两类编号不能使用同一个 Key。“应用设置”和“导出 CAD”为独立操作，并保留最近一次导出的状态与时间。 Exports the latest complete result from step two without rerunning Make2D. The model number and its fabrication number can be mapped separately to attribute keys that actually exist in the border; the two identifiers cannot share one key. “Apply Settings” and “Export CAD” are separate actions, and the latest export status and time remain visible.

01 获取 CAD 图框01 Get CAD Border

从标准 DWG 模板读取一个图框块实例、块属性、外框和有效绘图区。嵌套图层可按路径末端名称识别，已读取的模板结果会被复用。 Reads one border block instance, its attributes, outer boundary, and usable drawing area from a standard DWG template. Nested layers can be identified by the final segment of their layer path, and previously read template results are reused.

02 图框属性02 CAD Border Attributes

将 Keys 与 Values 组合为图框属性数据。数量不一致、空 Key 或重复 Key 会直接提示；Key 的匹配与去重不区分大小写。 Combines Keys and Values into border-attribute data. Mismatched counts, empty keys, and duplicate keys are reported immediately. Key matching and duplicate detection are case-insensitive.

03 预计算图框比例03 Pre-calculate CAD Border Scale

根据模板有效绘图区、待放置图元范围和目标平面计算适配比例。结果会保留约 5% 余量、向上取整，并再次检查内容是否完整落入有效区域。 Calculates a fitting scale from the template’s usable area, the geometry bounds, and the target plane. The result includes approximately 5% clearance, rounds upward, and is checked again to ensure the content fits inside the usable area.

04 生成图框并导出 CAD04 Generate Borders and Export CAD

批量处理多个图框，输出预览、最终比例和处理报告，并在导出图元后复制模板中的原生图框块。仅写入模板真实存在的属性 Key；带图层标签的图元按角色建立 CAD 图层，无标签图元默认进入“LK拍图::实线”。 Processes multiple borders in batches and outputs previews, final scales, and a processing report. After exporting geometry, it copies the original border blocks from the template. Only attribute keys that exist in the template are written. Tagged geometry creates CAD layers by role, while untagged geometry defaults to “LK Drawing::Continuous.”

导出过程提供进度和停止请求；覆盖旧文件前会确认，并对文件占用、备份及失败或取消后的恢复进行处理。预览与 CAD 使用一致的插入点、旋转、统一比例和单位换算。 Export provides progress and stop requests, asks before replacing an existing file, and handles file locks, backup, and restoration after failure or cancellation. Preview and CAD placement use the same insertion point, rotation, uniform scale, and unit conversion.

图层图元Layer Geometry

为 Grasshopper 图元附加 LK 图层角色，并可从组件菜单切换默认图层类型。标签可继续传递给颜色预览、烘焙及 CAD 出图流程。 Attaches an LK layer role to Grasshopper geometry and lets you change the default layer type from the component menu. The tag continues into color preview, baking, and CAD documentation workflows.

分解图层图元Deconstruct Layer Geometry

从带标签的图元中取回原始几何和默认图层名称，便于检查分类结果或接入自定义图层逻辑。 Retrieves the original geometry and default layer name from tagged geometry for checking classifications or connecting custom layer logic.
