Bob sent an email yesterday announcing that openNURBS 6 is now available. It also has a link to Food4Rhono so you can update your product availability for Rhino 6. Food4Rhino in turn has a link to this page in order to get the latest Rhino 6 SDK. The C++ SDK link here is broken.
Chrome.
The link on your page works fine. The “C++ SDK” link on this page is the broken one. So either this link needs to be fixed or your link changed to point to the correct SDK page.
Can you provide us a link to the page has the incorrect SDK link? Perhaps a screen shot might help. We seem to be having difficulty finding what you’ve described.
