What is CTB?
CTB refers to a file that is used in AutoCAD, a software for drawing and drafting. Specifically, a CTB file corresponds to a plot-style table that is dependent on color in the AutoCAD environment. When using AutoCAD, the CTB file is involved in instructing the application on how to plot specific drafts and drawings. It also serves as an intermediate file between different colors on an AutoCAD file, allowing for color attachments and display configurations to come up with a properly designed object. CTB files may contain plot styles that are color-dependent and/or mappings of various colors to different object layers.
AutoCAD is a famous software for designing, drawing, and drafting 2D or 3D graphics. It was initially developed back in 1982 by Autodesk specifically for CAD or computer-aided design purposes. Today, AutoCAD is compatible and can be installed and properly run on various platforms including Windows operating systems, Android systems, and Mac OS X. Back in its early days, AutoCAD was considered one of the pioneers in computer-aided designing using personal computers. In the early 80s, much of electronic design and drafting can only be done on mainframe and bigger computer terminals. By the time the IBM PC was rolled out, AutoCAD was among the first to be able to run on personal computers.
When users encounter the CTB file, it simply refers to a file that can be opened by the AutoCAD application or software. But when there are inconsistencies in the computer’s files, the CTB files may be corrupted and may prompt an error on the computer screen. Some viruses may also affect this particular file and so won’t be opened successfully even with the AutoCAD program. There are also times that registry files that are associated with the CTB file may be corrupted and so won’t allow the opening of this file. For concerns on the CTB file, one must coordinate with expert computer technicians so as not to further damage other files and the whole AutoCAD application itself.
