History

Initially developed in 1996 by M. Mottier for P. Lefevre to get an interactive
vision of the machine layout using CGM format

The current version of the navigator was developed in 1999 and was placed in
operation in 2000 for the LHC optics version 6.2 (6 versions approved since)

DWF files are computed with AutoCAD R14 to get the visualization

HTML, Javascript and Whip! Plug-in are used to get the page layout and the
interactions with the drawing layers, named views, links, information…
 Since the initial developments almost no revision to follow AutoCAD updates nor
HTML specification versions

When it was developed it has to work on all platforms supported by CERN:
Windows, Mac, Unix; whatever the navigator: Internet Explorer, Netscape

Remarks

Since AutoCAD 2004, the DWF format used in the Web Navigator is no longer available

Whip! Plug-in is no longer supported:



Works with Internet Explorer
No longer compatible with Netscape, Chrome, Opera, Safari…
Only 256 colors are supported
 All Stephen’s drawings have to be adapted
 QA policy: the file used to generate the DWF has to be the one uploaded for the CDD archiving)
 The current soft use (DWF + HTML + Javascript + Whip! Plug-in) is tested, proven,
light and robust BUT it’s 12 years old.
