The vector image data provides instructions to the CAD application about how to display the DWG on screen.
DWG file is a binary file that contains vector image data and metadata. The DWG files created by CAD applications are used industrially by architects, engineers and designers.Ī. Autodesk have robustly resisted attempts to reverse engineer the DWG format by other freeware applications building watermark protection into certain versions. The DWG format is licensed to Autodesk for their AutoCAD application which is the de facto standard for CAD drawings. One of the oldest file types, it was initially conceived in the 1970s for use with the early Computer Aided Design (CAD) devices for 2D and 3D drawings. They do not encode information that is specific to the application software, hardware, or operating system used to create or view the document.

A PDF file can be any length, contain any number of fonts and images and is designed to enable the creation and transfer of printer-ready output.Įach PDF file encapsulates a complete description of a 2D document (and, with the advent of Acrobat 3D, embedded 3D documents) that includes the text, fonts, images and 2D vector graphics that compose the document. since all your customized files will live in a non-Autodesk supplied directory.PDF is a file format developed by Adobe Systems for representing documents in a manner that is separate from the original operating system, application or hardware from where it was originally created. LIN files, or which one is the default, or which one should you edit, or even keep you from mistakenly deleting your "good" version. This will eliminate confusion regarding multiple. cui, etc.) Then when you upgrade, all you have to do is add "C:Thomas" to the top of the support file search path. Put anything else in this directory that you have created for yourself (acaddoc.lsp, acad.lsp. Put this path at the TOP of your support file search path, and then save your modified copy of "acad.lin" in C:Thomas. For example, create a "C:\Thomas" directory. If you are planning to modify "acad.lin" or create your own "thomas.lin" for example, then you should start your own customization directory if you have not already.

True, AutoCAD will point you to a "acad.lin" file as "richards.64879" said while in the LINETYPE command, but you are free to load linetype definitions from any.
The original request was about finding the "acad.lin" file as if there is only one that AutoCAD will read. They both search the support file search path for the first "acad.lin" file. The method of finding the file that "richards.64879" wrote about is identical to the (findfile.) lisp trick. There is certainly no guarantee that the "hidden" linetype in a drawing you have is the same as the definition of "hidden" in any given. Upon opening of a drawing, it won't make any difference. You could have 10 different "acad.lin" files, or none of them. Linetype definitions are stored in the drawing file, so there is no "currently-loaded file", or "currently referenced 'acad.lin' file" as I badly put it. My earlier post was bit misleading, as is the follow up post suggesting that there is a "currently-loaded file".
