3D CAD* Viewer is a fast and easy app for high-quality visualizing and saving your CAD files converted in the most popular formats to avoid having to search for and install special software on your device. You can get detailed information about your CAD models and drawings without subscribing and registration.

*CAD (Computer Aided Design) is a software for drawing complicated shaped designs on a PC instead of manual drawings. All modern aircraft, engineering, and architecture create by using CAD software.

This CAD 3D Viewer app helps visualize 3D models and perform export operations. Our app will let you convert your file to the most popular raster or vector file format and download it after conversion to make them useful to any site or device.
View the drawings online on any platform: Windows, macOS, Linux, Android, or IOS from everywhere. See detailed contents of your file by clicking Show/Hide properties. All processes run on our servers and do not take resources from your device.
All you need to do is upload a CAD file from your device or put a URL to a file to the relevant places and wait to see the results on the current page.

1 file per 3D view process!

Open, visualize, and compress your files to save your software, hardware, and the cost of maintenance, training, and time.
Our app is a virtual instrument powered by Aspose.CAD offering drawing processing features on-premise and ready for client & server-side use.
Powered by Aspose.CAD, Aspose.com and Aspose.cloud. All files are processed with Aspose APIs, which are being used by many Fortune 100 companies across 114 countries.
If you want to access your drawings using our API, please check Aspose.CAD documentation. Our API is useful for developers and comes with great documentation, clear code samples, and an all-dev support team.

Other Supported Formats

You can also view files in other formats. See the complete list below.

  1. DXF
    (Drawing Interchange Format) or (Drawing Exchange Format)
    Vector file format for enabling data interoperability between AutoCAD and other programs. DXF is an open-source file format that lets you avoid Autodesk programs. DXF files stay accurate before and after the conversion.

    You will need to convert DXF files to an STL format to print them in 3D.

    The user needs to know the drawing unit because DXF coordinates are always without dimensions.
    DXF files are most popular in transferring the design details among parties engaged in designing, building, and maintaining buildings, aircraft, ships, etc.
  2. DWG
    DWG is a compact binary file format with closed-source software for containing 2D and 3D design data and metadata in a highly compressed form. DWG is appropriate for storing large design files but makes them difficult to use without special software.

    Closed-source (antonym for open source) software is proprietary or non-copyrighted software.

    Primary used for creating the design drawings and models, deriving renderings in 2D or 3D, and collaboration among architects and engineers designing, constructing, and maintaining buildings.
  3. DGN
  4. DWF
    (Design Web Format)
    Secure file format for the efficient distribution and communication of rich design data to view, review, or print design files. A DWF file can describe design data containing any combination of text, graphics, and images in a device-independent and resolution-independent format. DWF files are highly compressed, smaller, and faster to transmit. You can limit the specific design data and plot styles, and publish multi-sheet drawing sets from multiple AutoCAD drawings in a single DWF file. DWF allows designers, engineers, and project managers communicate design information and content design without needing them to know AutoCAD or other design software.
  5. DWFX
    (Design Web Format XPS)
    2D and 3D drawings as XPS1 documents.

    Microsoft's XPS format was designed as a final-state format for printing, distribution, and viewing to end users.

    It contains graphics and text as part of the design data. The XPS format lets you share the design data with reviewers without requiring them to install Autodesk Design Review. DWFX is the compressed format for making transmission over the internet suitable. A single DWFX file is usually bigger than the corresponding DWF file and can contain one or more drawings.
  6. IFC
  7. STL
    STL has several backronyms such as "Standard Triangle Language" and "Standard Tessellation Language".
    Most popular file format for 3D printing, rapid prototyping, and computer-aided manufacturing.
    Each file is a series of linked triangles that describe the surface geometry of a 3D model or object. The more complex the design, the more triangles used, and the higher the resolution.
    STL supports by many software packages. STL files describe only the surface geometry of a 3D object without any representation of color, texture, or other common CAD model attributes. The STL format specifies both binary and ASCII representations. Binary files are more common since they are more compact.
  8. DWT
  9. IGES
  10. PLT
    3D Viewer for Plotter file
  11. CF2
  12. OBJ
    (Object file)
    An OBJ file is a standard 3D image format that can be exported and opened by various 3D image editing programs. It contains a 3D object, including 3D coordinates, texture maps, polygonal faces, and other object information.
    It is a universal 3D model format since 3D image editing apps widely support it. OBJ is a text-based and straightforward but simple format structure that also leads to big OBJ file sizes to store large and complex 3D objects.
  13. HPGL
  14. IGS
  15. PCL
    3D Viewer for PCL
  16. FBX
  17. PDF
    (Portable Document Format)
    The universal file format to preserve the fonts, images, and layout of the original document on many platforms or any apps they were created. PDF is compatible with all major platforms, compact and supports digital signature technology. PDF was first standardized as ISO 32000 in 2008.
  18. SVG
    (Scalable Vector Graphics)
    An XML-based vector image format for defining 2D graphics with supports for interactivity and animation.
    SVG images are defined in a vector graphics format and stored in XML text files. SVG images can be scaled in size without loss of quality. SVG files can be searched, indexed, scripted, and compressed. The XML text files create and edits by text or vector graphics editors, and renders by the most popular web browsers.
