Identify the respective CTB file linked to the autocad drawing file

wrenchinternal · ‎12-09-2013

I have linked a CTB file to the drawing file in autocad. Now i wanna convert the dwg to pdf using autocad api.I need to use the respective CTB file linked to the dwg while coverting.If I have a set of CTB files with me, how can I identify the respective CTB file using API in .NET?

CTB file (plot style sheet) used in a drawing file is associated to layouts in the drawing. So, if you want to identify what CTBs are used in a drawing file, you need to loop through all layouts in a drawing and find Layout.CurrentStyleSheet property, which is a string value of the CTB name.

Hope this answers your question.

Don't forget Named Plot Styles (PlotSettings). The CTB files referenced by the PlotSettings may not be visible or used but still are referenced.

Thank you very much for your replies. Since i am a new bie in Autocad, if you could help with some C# code to loop through all the layouts in a particular document, that would be very helpful. Mean time i will try my very best to find a way to crack it.

I did not really get what you meant. If you could explain it, that would be wonderful. Thank you very much for your effort.
