Plugin-free RapidAuthor publications (parts catalogs, maintenance manuals, work instructions) can be viewed online or offline.

Offline viewing with RapidAuthor Viewer

RapidAuthor Viewer was designed for viewing the plugin-free RapidAuthor publications stored locally on the user’s computer.

RapidAuthor Viewer allows for viewing the publications publications created with standard specification components of RapidAuthor. Support for customized publications will be added in the future releases.

RapidAuthor Viewer is included in the RapidAuthor installation package (starting from v. 13.1) and can be downloaded from the Cortona3D website:

Offline viewing with web browsers

The Cortona3D Solo library downloads its components and interactive publications from external files. Due to the Web browsers security restrictions (See the Same origin policy article for more information), loading from a file system will fail with a security exception. 

There are several ways to solve this issue:

  1. Change security settings for local files in a browser (this allows you to access your page as file:///yourFile.html). More detailed information about settings is provided below.
  2. Run files from a local web server (this allows you to access your page as http://localhost/yourFile.html). A sample of a local web server can be provided on demand.
  3. Pack all data into one HTML file while publishing your project in RapidAuthor (Tools > Publish Options, Create Single HTML Bundle = Yes); please note that this method is not compatible with Internet Explorer.
