When creating DWG-files that are used for production of blue prints the mappning between colors in AutoCAD and eg. linewidth in the PDF/paper are controlled with a plot style table in a filed called ctb. Every paper space in the DWG-file can be associated with a ctb-file. It is important to verify that the correct ctb-file is used.
FME cannot read the information about which ctb-file that is associated with the paper space. This idea is for reading the name of the ctb-file for the DWG-formats in FME.
