BackToCAD Publisher is a stand-alone Windows x64 converter that processes hundreds of DWG/DXF files into 2D PDF, 3D PDF, and PRC, the latter used for 3D PDF or CAD input. It creates 3D PDF or PRC alternatively with Net Models or B-Rep Models, and supports 2D CAD elements such as Text, Line, Polyline, Dimension, and Hatch inside 3D PDF.
For color and line weight conversion it can use Autodesk AutoCAD Plot Style CTB files or an internal conversion table. It offers several scale and unit calculation methods for PDF or raster output, and supports paper space, model space, and active layout along with margins and page sizes of different sizes. Layouts can go to separate PDFs, one full DWG to one PDF, or several selected drawings to a single PDF.
It embeds searchable text, binds DWG external references and raster images, and lets users place a watermark on 2D PDF, 3D PDF, or PRC. PDFs are generated at up to 40,000 DPI with optimized polylines and curves.
