DWG to PDF

Foxit PDF SDK has added a powerful DWG to PDF function since version 10.0, aiming to meet the needs of users in engineering, design and other fields for converting CAD drawing files. This function allows developers to convert 2D graphics files in DWG format into PDF documents with high precision through simple API calls, retaining the layout, size and details of the original drawings.

This feature has the following features:

• High-precision conversion: Ensure that the converted PDF file restores the original visual effects and data information of the DWG file as much as possible.
• Flexible output settings: Developers can set various parameters for PDF output according to their needs, such as page size, embedded fonts, layer control, etc.
• Cross-platform support: Supports mainstream operating systems such as Windows, Linux and Mac, making it easier for developers to integrate into different application environments.
• Multi-language support: Supports multiple programming languages ​​such as C, C++, Java, C#, Python, Objective-C, Node.js, go, etc.

Through the DWG to PDF function of Foxit PDF SDK, developers can easily integrate CAD drawings into PDF workflows to achieve convenient sharing, long-term archiving and efficient printing of drawings. To get started quickly, developers can refer to the DWG to PDF Example Configuration and Operation Guide to learn about the configuration steps and running examples, and quickly master how to use this function.

Convert DWG files to PDF

The following code demonstrates how to configure a DWG2PDFSettingData object, set export options, and then call the Convert.FromDWG method to perform the conversion.

Layout scope and title blocks

Starting with 12.0, prefer DWG2PDFSettingData::layout_scope to specify the export layout scope; the former is_active_layout is deprecated. For the export_hatches_type default change, see Release notes · export_hatches_type.

Common layout_scope values include: model space only, current layout, all layouts, model plus layouts, frame/title blocks (e_DWG2PDFLayoutScopeFrameBlocks), drawing extents, auto overflow, automatic rectangle tiling (AutoRects), and by layout index. When exporting by title block, set frame_block_configuration_path to an XML configuration that lists <TitleBlock Name="..."/> entries.

You can also use fields such as maximum_drawing_area, minimum_export_rect_side_length, lineweight_style_mode, and geometry_image_output_dpi to control tiling filters, line weight, and output DPI. See the API Reference for details.
