CIS/2 - IFC Gap Analysis

[Robert Lipman]

Hi,

At the AISC CIS/2 workshop in Chicago on 18 December 2009, one of the
action items was to develop a CIS/2 - IFC gap analysis. The purpose
of the analysis is to identify the issues related to modeling
structural steel in IFC relative to how is it modeled in CIS/2.

The analysis has identified many issues, how they are handled in
IFC2x3, workarounds or alternatives for IFC2x3, how they will be
handled in IFC2x4, and how they are modeled in CIS/2. There is also
a section of other comments and questions related to the analysis.

In general, the analysis shows that there are areas of improvement for
the IFC schema and software implementations. They include:
improvements for detailed or fabrication models; incorporating some of
the semantic information that is found in CIS/2; and improving the
geometric modeling of structural steel.

You can download the analysis from http://cic.nist.gov/vrml/cis/CIS2_IFC_Gap_table.pdf

Thanks a ton for this information.

Asked about it often. Can we use this or distribute this info?
