| A new version (4.5) of the CIS/2 to VRML Translator is available. This
is a significant upgrade to previous versions.
If you're a current user of the translator, then in the translator, go
to Help menu -> Check for Upgrade. Or you can download the translator
for free at: http://ciks.cbt.nist.gov/cgi-bin/ctv/ctv_request.cgi
CIS/2 (CIMsteel Integration Standards) is the product model and data
exchange format for structural steel project information. It has been
adopted by the AISC for their Electronic Data Interchange initiative.
CIS/2 has been implemented by many steel analysis, design, detailing,
and fabrication software packages. For more information about CIS/2, go
to: http://www.aisc.org/cis2 http://www.cis2.org/

VRML is the Virtual Reality Modeling Language, a standard method to view
3D model on the web with freely available plugins:

Many example VRML structures, including the AISC connection sculpture,
are available at: http://cic.nist.gov/vrml/cis2.html

NEW FEATURES:
1. Much faster translations and lots of bug fixes. Without any optional
display features turned on translations are at least 40% faster and even
faster for large detailed models.
2. Better support for metric and nonstandard sections, joists, double
angles. Joists and double angles look more realistic.
3. Improved summary report: bolts are now included, improved weight
computation, text popups can be generated at the same time as the
summary report. Sample summary report:

4. Support for surface treatments, curved parts, shear studs, barcodes,
cost codes, grid lines, fabrication properties
5. Color by grade, sequence, surface treatment, fabrication property
For those of you who are using the translator, I would appreciate
feedback and suggestions.
Thanks,
