3D Interoperability

The SaveVersion option documentation states:

"Back saving is supported only up to 1800"

This limitation makes InterOp pretty much useless for someone like me trying to write an IGES or STEP file import plug-in for a CAD system like say AutoCAD. Even the latest version of AutoCAD reads SAT upto version 7.0.

Am I missing something here?

Hi Deelip,

Our backsaving is limited to 1800 in order to support PMI information - which were introduced in InterOp R18. However if you are only interested in back saving Brep data, you can use InterOp to generate ACIS ENTITY_LIST in memory and use ACIS back save (api_save_version( )) for older ACIS versions.

Thanks,

Vivekan

Thanks for your reply.

I see that api_save_version() is not part of InterOp.So do you mean that just for this one thing I would need to license ACIS apart from InterOp? I hope not.

Hi Deelip,

api_save_entity_list() and api_save_version are ACIS APIs that are included in the Viz Exchange product that you have (and ACIS Exchange as well).  You needn't license anything more than you already have.

Best,

I am relieved to hear that. Please do excuse my ignorance. I just got started with your libraries and the sheer size of them scares the hell out of me ;-)

Using the AcisImport example as a guide I managed to get InterOp to save to previous versions of ACIS.

Thanks for the help.
