Teigha Library Error 2018

Recommended Posts

To rule out the possibility that the DWG you’re trying to import is too new for the version of Vw you’re using, open the DWG file in a text editor application, like either macOS ‘TextEdit’ or Windows ‘Notepad’. The first six characters in the DWG file header will tell you the file version as follows:


AC1009 - DWG Release 11/12 (LT R1/R2) 
AC1012 - DWG Release 13 (LT95) 
AC1014 - DWG Release 14, 14.01 (LT97/LT98) 
AC1015 - DWG AutoCAD 2000/2000i/2002 
AC1018 - DWG AutoCAD 2004/2005/2006 
AC1021 - DWG AutoCAD 2007/2008/2009 
AC1024 - DWG AutoCAD 2010/2011/2012 
AC1027 - DWG AutoCAD 2013/2014/2015/2016/2017 
AC1032 - DWG AutoCAD 2018


The Vw2018 Help File says that “As of this writing, the most recent DXF/DWG version is version 2018. The Vectorworks program imports versions 2.5 through 2018, and exports versions 12 through 2018.”


@Moto2 as you’re having this problem in Vw2018, this should not be the cause of the Teigha problem that you’re having.
