## What is Cortona3D Viewer?

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.

Features:

— AR support for procedures and VRML scenes
— Multi-touch gestures for navigation

### 2/5 — .wrl perhaps, but no HAnim that I can figure out

*2023-11-15*

I bought the app because the literature said it viewed VRML files.  It recognizes the .wrl extension, but I couldn’t view HAnim data (HAnim v2 is from 2019).

### 5/5 — 非常流畅，简洁易用高级工具

*2019-12-20*

谁用谁知道

### 1/5 — Doesn’t support VRML (*.WRL) files

*2018-10-02*

App is very limited.

### 4/5 — Opens vrml

*2016-07-01*

Works good,needs more tool and More file extensions but all in all thanks for a good app but you can make it a great app

### 2/5 — Not a browser plugin

*2015-04-27*

It was not made clear, at least to me, that this is not a browser plugin like the windows version. Unfortunately, that is what I need as the manufacturer (Winnebago) does not make the parts catalog available for download. I am forced to rate this APP but I can’t really do it fairly as it does not do what I was hoping it would but maybe it works well for other uses.
