- Add AcApPdfConvertor: reuses AcSvgRenderer pipeline, converts the resulting SVG to a vector PDF using jsPDF and svg2pdf.js - Add AcApConvertToPdfCmd: thin command wrapper, registered as 'cpdf' - Register 'cpdf' command in AcApDocManager.registerCommands() - Add 'Export to PDF' menu item in MlMainMenu.vue - Add exportPdf i18n key to en/zh locale files
- Add AcApPdfImportConvertor: loads PDF with pdfjs-dist, walks the operator list (moveTo/lineTo/curveTo/closePath), converts path segments to AcDbPolyline / AcDbLine entities, appends to model space - Cubic bezier curves approximated as 8-segment polylines - Coordinates scaled from PDF points to mm (1pt = 25.4/72 mm) - Y-axis flipped to match CAD coordinate convention - Add AcApImportPdfCmd: thin command wrapper, registered as 'ipdf' - Register 'ipdf' command in AcApDocManager.registerCommands() - Add 'Import PDF' menu item in MlMainMenu.vue - Add importPdf i18n key to en/zh locale files

@4ni1ak Is it possible to implement it as one plugin so that users can use it on demand because currently thei size of cad-viewer bundle isn't small any more. So I created plugin mechnisam to handle it. You can find the related code in folder 'packages\cad-simple-viewer\src\plugin'. |
