Cortona3D Viewer5.0 - App Store

Cortona3D Viewer is your tool for interactive 3D and 2D product catalogs, work instructions, maintenance guides, and manuals created using Cortona3D RapidAuthor. With this tool, you can immerse yourself in 3D procedures and VRML scenes through augmented reality on your iPhone. Many equipment manufacturers are now enhancing their technical documentation. The Cortona3D Viewer supports AR, 3D interaction, full-text search, and interactive 2D elements, making it compatible with both legacy 2D and interactive 3D content derived from CAD.

Interactive 3D streamlines complex maintenance and assembly communication, aids part identification, and facilitates mechanical skill training. It can also serve as a sales tool for product feature demos.

Cortona3D Viewer on iOS complements RapidAuthor tools. RapidAuthor generates comprehensive technical documents with text, 2D, and 3D graphics from CAD and bill of materials data. Even if your company doesn't use Cortona3D RapidAuthor, you can still install Cortona3D Viewer to access sample content featuring 3D, legacy 2D graphics, and AR elements.
