 +==== IGES ====
 +OpenVSP relies on the [[http://​cbernardo.github.io/​libIGES/​|libIGES]] library for exporting IGES files in accordance with the IGES v5.3 standard. The IGES format is compatible with most CAD packages. The STEP format, which functions as a predecessor to IGES, is also available. IGES exports may be of untrimmed components, trimmed components, untrimmed structural models, or trimmed structural models. ​

 STL files contain a large amount of redundant information. ​ Consequently,​ they can be very large for a given model -- as much as six times the size of other ASCII formats. STL files contain a large amount of redundant information. ​ Consequently,​ they can be very large for a given model -- as much as six times the size of other ASCII formats.

 +==== STEP ====
 +OpenVSP uses the [[http://​stepcode.github.io/​|STEPcode]] library to export Part 21 exchange files for interfacing with CAD programs. Alternatively,​ the IGES is also available for exporting to CAD. OpenVSP supports STEP export of untrimmed components, trimmed components, untrimmed structural models, and trimmed structural models. ​
