All seems o.k. until I go to the 3D window, where I get the OpenGL error message / report in my screen shot below. Any idea what would be causing this? I have simply opened it in AC16 and consolidated Libraries, that is all.<BR /> <BR /> Cheers</T></DIV><BR /><IMG src="http://community.graphisoft.com/t5/image/serverpage/image-id/71300i2793F89684DE0B36/image-size/large?v=v2&amp;px=999" border="0" alt="Screen shot 2013-03-01 at 11.23.57 AM.png" title="Screen shot 2013-03-01 at 11.23.57 AM.png" /> Fri, 26 May 2023 12:24:07 GMT https://community.graphisoft.com/t5/Modeling/3D-error-of-AC15-file-in-AC16/m-p/123966#M65791 Anonymous 2023-05-26T12:24:07Z https://community.graphisoft.com/t5/Modeling/3D-error-of-AC15-file-in-AC16/m-p/123967#M65792 Traced the problem to an object from the Foraform furniture library.
