This plugin doesn't work for me. I Draw a simple cube in rhino, export as 3ds, import into ArchiCad 11 (Intel Mac) and voila, some stupid error that means I have to force quit archicad. First I get: "ACAPI_LibPart_Create Error: 1", then if you click okay, it moves on to "ACAPI_LibPart_UpdateSection paramdef Error: 104", then you have to force quit.
If you're going to make archicad so unfriendly to other file formats, (still no sketchup importer for mac) at least make the things that you do release work...
