DG Kernel Forum

Just looking to document which flavor of IGES is being exported. OC mentions "up to 5.3", but can you clarify which version you are exporting? Thanks!

It is v5.3.

We do not do anything special in DGK 7.2 with it. We have updated this functionality last year and just call the relevant OCCT 7.7.0 API. Specifically IGESControl_Writer class.

OCCT does not concern themselves with iges versions. I do not see anything specific in their code and they do not write version in the header. It is pretty old format with many limitations.

Thanks, Prashant. We also were surprised to find that the IGES header was not more fully descriptive. The export is working very well for us, this was just to document the version as we have our own IGES file creator (in v4 format).
