A customer has sent me a 3dm file which my openNURBS v7-based software cannot read; ONX_Model::Read returns false. Allegedly this file has a SubD object, and if they delete the SubD object and try to import that version of the file, it works fine. (For comparison, if I try to read the v7_rhino_logo_subd.3dm example file, ONX_Model::Read returns true, though my software doesn’t actually do anything useful with the SubD objects yet.)
Um, I’m hoping I get a chance to attach said file at some point in this topic creation process, and then hoping that you guys can take a peak and tell me if the file is correct or not. Or that this problem will ring bells with someone out there.
