Edit .dwg according to a rule or a business scenario.  \nSave  \nSave your changes seamlessly to .dwg files, ensuring compatibility across different versions of AutoCAD and other .dwg-compatible applications.  \nVisualize .dwg, .dxf and .dgn on any platform  \nRender .dwg and .dgn files seamlessly across platforms with fast performance and a comprehensive feature set. Advanced techniques like spatial filtering ensure smooth rendering, even for large models. Navigate with ease using standard tools like zoom, pan, and 3D rotation. Achieve realistic visuals with customizable materials, lighting effects, and visual styles, including hidden edges and transparency.  \nPoint Cloud Support  \nImport, visualize, and manipulate large point cloud datasets within .dwg files, facilitating detailed analysis and 3D modeling.  \nConversion  \nExport: .dwg, STL, 2D, PDF, 3D PDF, OBJ, Collada, SVG, Raster  \nImport: Collada, .dwf, STL, SVG, 2D PDF  \nRevision Control  \nImplement version control in your .dwg files, allowing you to track changes, revert to previous versions, and manage file history.  \nIncremental Saving for .dwg Files  \nDrawings SDK has an incremental file saving feature for .dwg files that saves only modified data, which is faster than a full save for large files that don't contain a lot of modifications.  \nPartial and Multithreaded (MT) Loading of .dwg Files:  \nSupports partial loading, allowing users to load only the necessary parts of large .dwg files to enhance performance. Multithreaded loading further improves speed by utilizing multiple CPU cores for faster access to complex drawings.  \nDigital Signatures for .dwg Files  \nProvides functionality for validating and applying digital signatures to .dwg files, ensuring file integrity and authenticity. This feature is essential for maintaining the security of drawing files in professional workflows.  \nWorking with Geo-Data  \nWe provide special classes for working with geo-data as well as access to third-party libraries such as csmap, curl and tinyxml. Sample code is available as well.  \nRecover/Repair Incorrect Files  \nUse built-in tools to automatically detect and fix corruption or errors in .dwg files, ensuring data integrity and usability.  \nDynamic Blocks Evaluation  \nProvides full support for dynamic blocks, allowing users to interact with them within DWG files. Modifications can be implemented using our library to recalculate dynamic blocks based on new parameters.  \nTTF/SHX Fonts Support  \nEnsures compatibility with both TrueType (TTF) and SHX fonts, accurately rendering text within .dwg files. This includes support for a variety of font styles, ensuring that the appearance of text remains consistent across different platforms.  \nNative Support for 3D Modeling Operations  \nProvides built-in support for basic 3D modeling operations within .dwg files. This functionality is developed internally by ODA and offers essential 3D modeling features at no additional cost, but with limited capabilities.  \nConstraints  \nApply and manage geometric and dimensional constraints to maintain relationships between objects, ensuring design accuracy.  \nWrappers  \nAccess the functionality of the Drawings SDK not only in cross-platform C++, but also through easy-to-use wrappers for C\\#, Python and JS, streamlining development processes.  \nCommon Data Access (CDA)  \nUtilize CDA to abstractly access and manage d","cbCaiiCTXPQFU34V","https://ap.wps.com/l/cbCaiiCTXPQFU34V","pdf",260918,13,"English","# Supported file formats\n## Drawings features\n## Sample applications","[{\"question\":\"Which CAD file formats are supported by Drawings SDK and Drawings inWEB?\",\"answer\":\"Drawings SDK supports .dwg, .dgn, and .dxf, while Drawings inWEB supports only .dwg and .dxf for now.\"},{\"question\":\"What are the main features for editing and saving DWG files?\",\"answer\":\"The SDK provides tools to modify DWG geometry, metadata, and object properties, and it saves changes with compatibility across AutoCAD versions.
