It should be easy enough to find a software that can convert CATIA technical drawings and parts (.catpart) and export them to IGES format (.igs, .iges). The first choice would be of course some of the Dassault Systemenes CAD programs (including CATIA), but you may also find some 3rd party programs that support CATIA formats.

The tables with software actions are a good pointer for what a certain program does with various file types and often may give users a good hint how to perform certain file conversion, for example the above-mentioned catpart to iges. However, it is not perfect and sometimes can show results which are not really usable because of how certain programs work with files and the possible conversion is thus actually not possible at all.
