★★★ IMPORTANT - CORELDRAW IS REQUIRED ON THE CUSTOMER'S COMPUTER ★★★ * CorelDRAW must be installed on the customer's PC, otherwise NEITHER command works. For support: zhantunet@139.com Please verify that CorelDRAW is installed on the machine where this plug-in will run BEFORE installing. BOTH commands (ImportCDR and ExportCDR) drive CorelDRAW through its COM automation interface: reading a .cdr file launches/attaches CorelDRAW, and writing a .cdr file does the same. On a computer without CorelDRAW, NEITHER command works - there is no fallback built into this plug-in. If the customer's machine has no CorelDRAW, prepare the drawing on a machine that does (save as DXF or SVG) and open that file natively in Rhino instead. ================================ ★★★ 重要：客户机器必须已安装 CorelDRAW ★★★ ★客户机器必须装 CorelDRAW，否则两个命令都不可用；有问题请联系 zhantunet@139.com。 安装前请先确认客户电脑上装有 CorelDRAW。本插件的两个命令 ImportCDR（导入） 与 ExportCDR（导出）都通过 CorelDRAW 的 COM 自动化接口读写图纸：导入时要启动/连接 CorelDRAW 读文件，导出时同样要启动/连接 CorelDRAW 写文件。客户机器没装 CorelDRAW 时，两个命令都无法工作， 插件内部没有替代方案。遇到这种情况，请在装有 CorelDRAW 的电脑上把图纸另存为 DXF 或 SVG， 再用 Rhino 原生打开。 ================================ CorelDRAW (.cdr / .cdt) importer AND exporter for Rhino 8 / 9 - standalone build, two commands. ImportCDR - type the path to a .cdr/.cdt file, or press Enter to open the file picker. Shapes are rebuilt as native Rhino curves and grouped onto layers by CDR layer or by outline color (your choice at the prompt). Broken gaps between adjacent segments are repaired automatically, so contours come in closed instead of fragmented. Cubic Beziers, arcs and ellipses are kept as exact NURBS, text is converted to curves during pre-processing, and the view zooms to the imported geometry when finished (CDR drawings often sit far from the origin, which is why a successful import can look empty). ExportCDR - writes Rhino curves back to a .cdr file. Choose to export selected curves only (default) or every curve in the document, then type a save path or use the file dialog. Layers and outline colors are preserved. Polynomial cubic Beziers are re-emitted exactly; rational curves (arcs, weighted splines) are approximated by adaptive polylines with a 0.005 mm chord-height tolerance, so a round-trip through CDR does not degrade the geometry into short line segments. Document units are converted to mm and the drawing is centred on the CDR page. Read and write share one data model, so importing a file and exporting it again is numerically verifiable. Both commands show a status-bar progress bar for long operations and ESC cancels safely at a checkpoint (partial results from a cancelled import are kept). Every prompt follows the Rhino UI language: Chinese on a Chinese Rhino, English elsewhere. Layer names stay as data identifiers and are never translated. REQUIREMENT (repeated): CorelDRAW, installed on the SAME computer as Rhino. This plug-in contains the CDR importer and exporter ONLY. Wentai ArtCut (.ac6) import and all sheet-metal commands are not included, and no other Zhantu plug-in is required. NOTE: the command names ImportCDR and ExportCDR are shared with SpreadAssistantIO - install only one of the two in the same Rhino. Built with the Rhino 8 SDK; Rhino 6/7 are not supported. RELEASE: version 0.9.0 is published on the official Yak server (yak.rhino3d.com); find and install it from Rhino's Package Manager. There is no trial period and no built-in time lock; an installed copy keeps working. ================================ CorelDRAW (.cdr / .cdt) 导入 + 导出插件（Rhino 8 / 9 独立版），两个命令。 ImportCDR 导入：输入 .cdr/.cdt 路径，或直接回车弹出文件选择框。图形重建为 Rhino 原生曲线， 按提示选择「按 CDR 图层」或「按颜色」分图层；相邻段之间的断点会自动修复，轮廓不会碎成断线。 三次贝塞尔、圆弧、椭圆保留为精确 NURBS，文本在预处理阶段转曲，导入完成后视图自动缩放到本次 导入的内容（CDR 图纸常远离原点，这是「导入成功却看起来什么都没有」的原因）。 ExportCDR 导出：把 Rhino 曲线写成 .cdr 文件。先选导出范围（默认只导出选中的曲线，也可选全文档 曲线），再输入保存路径或用文件对话框。图层与轮廓颜色保留。多项式三次贝塞尔精确写回；有理曲线 （圆弧、带权样条）按 0.005 mm 弦高自适应折线近似，避免往返一次就把曲线劣化成一堆小线段。 文档单位换算为 mm 后居中落到 CDR 页面上。读写共用同一份数据模型，导入再导出可直接对账。 两个命令的长任务都显示状态栏进度条，按 ESC 可在安全点中止（导入已读到的部分会保留）。所有提示 跟随 Rhino 界面语言自动切换中/英文；图层名是数据标识，不翻译。 依赖（再次强调）：与客户机器上的 Rhino 同机安装 CorelDRAW。本版本只含 CDR 导入与导出，不含文泰 AC6 导入、不含任何钣金命令，也不需要安装本店其它插件。注意：命令名 ImportCDR / ExportCDR 与 SpreadAssistantIO 相同，同一台 Rhino 只能装其中一个；基于 Rhino 8 SDK 编译，不支持 Rhino 6/7。 发布说明：0.9.0 已正式发布到 Yak 官方服务器 yak.rhino3d.com，可在 Rhino 的包管理器中搜索安装。 无试用期限，插件内部也不带时间锁，已安装的副本可长期使用。
