CADconv 2020 is a stand-alone converter that allows the CAD user to convert hundreds of DWG/DXF files into
2D PDF, 3D PDF and PRC (3D Input for PhotoShop, Acrobt, etc.).


CADconv 2020 creates 3D PDF or PRC alternatively with Net Models or the B-Rep Models.


CADconv 2020 supports 3D PDF 2D CAD Elements like Text, Line, Polyline, Dimension, Hatch ...


CADconv 2020 can use the AutoCAD Plot Style CTB files or the internal conversion table for Color and line Weight Conversion.


CADconv 2020 offers several easy to use scale and unit calculation methods for PDF or Raster output.


CADconv 2020 supports paper space, model space and active layout as well as margins and page sizes of different sizes.



CADconv 2020 can convert each DWG layout to a separate PDF, one full DWG drawing to one PDF, or several selected DWG drawings to one PDF.


CADconv 2020 embeds searchable text, binds DWG external references and DWG raster images.


CADconv 2020 security function allows the user to place their own watermark onto 2D PDF, 3D PDF or PRC.


CADconv 2020 generates PDFs with very high quality of coordinates (up to 40.000 DPI) and with optimized polylines and curves.


CADconv 2020 supports DWG/DXF Version 12, 14, 2000/2002, and 2004 to 2019.


CADconv 2020 supports the modern High Speed DCT Compression and Linearization of PDF for Web (PDF shows on Web Page with no delay) .

3D PDF Output as PRC

3D PDF Output







As a part of the process of transitioning its 3D technology, Adobe established  the ISO standardization process for the PRC data format used in 3D PDF specification.


CAdconv 2020 supports ISO PRC formats (Product Representation Compact) for 3D PDF representation. You can mix 2D and 3D elements in the same PDF.


The free Acrobat PDF Viewer views each PRC model in a separate internal viewer. If you have a lot of separate models in your CAD system, every model will receive its own PRC viewer. This is because the idea of 3D PDF is to use it for parts catalogs and not for a viewing of a whole construction.


3D PDF internal viewer  for PRC models is a real time viewer and the PRC model can not be very complicated.


PDF viewer for PRC models change only the position of a model and not the position of an observer - the observer looks all time from the same position vertical to PDF page (see Image of 3D PDF above). You can not see the PDF page and 2D elements from another view angle or perspective like in your CAD system.


We support only the B-Rep (Boundary Representation) and Net Model of 3D Elements. We support  2D/3D line, 2D/3D polyline, 3D net definitions and 2D/3D Text.
