A DGN file is a 2D/3D drawing created by MicroStation or Intergraph Interactive Graphics Design System. Such files are typically used to save designs for construction projects for highways, bridges, and buildings.
3D PDF is a PDF file with 3D geometry inside. Using any 3D PDF enabled viewer, rotation, zoom and part selection is available within the 3D view.
3D PDF is just like a normal PDF (Portable Document Format) file, which contains a 3D view somewhere on some page. Just like a PDF containing an embedded image, except when you put the mouse over it, you can rotate, zoom, pan and explore the scene in 3D (three dimensions). The file actually contains a 3D geometric representation of the scene, not just images from different viewpoints.
A CAD file is an output of a CAD software, containing key information about the designed object: its geometry and topology representation, 3D model hierarchy, metadata, and visual attributes depending on the format of the file.Read more
In the 3rd and 4th parts of the series, we will talk about surface display modes in 3D CAD programs, starting with the shading mode.Read more
We continue to execute our mission to improve the import of massive 3D models. In 3.16 users will notice enhancements in both desktop and web visualization, as well as the extension of the support of the native file formats.Read more
