A graphical user interface (GUI) was a big part of AutoCAD’s success. The first time many users saw it was in November 1982, when AutoCAD was released for the Atari 800. That GUI enabled users to select objects, move them, and create new objects in a way that was very intuitive for the user. However, that GUI used a proprietary data structure that has not been ported to any other platforms. Autodesk developed a new data structure, the Graphical Data Management System (GDMS), in order to make AutoCAD more accessible to users on a wide range of platforms. AutoCAD 8 was the first release to use GDMS, and it was released in 1990.

The main drawback to AutoCAD’s GUI was that it was unable to display advanced color, curves, or gradients. Until AutoCAD 11, the only way to create custom color, curves, and gradients was through special commands. The first time users tried that was in AutoCAD 11 for the Mac. When AutoCAD first came out, some platforms didn’t even support color, which is why the app was often called “black and white”. Although the program could display many different kinds of color, it didn’t yet support RGB, CMYK, or even several other kind of color, such as indexed color or Pantone.

In 1991, GDMS also became an XML data format. XML was a response to the difficulties of creating a universal database across the different platforms. Prior to GDMS, the only database in AutoCAD was called “Materials”, which was limited to one kind of material only. It used files to store object information.

AutoCAD uses a preprocessor to convert objects from one data type to another. This is a lot like a compiler. The data is sent to the preprocessor, and then the preprocessor processes it and creates a new format that the next level of the software can understand. The graphics engine of AutoCAD runs on several different platforms, including 32-bit and 64-bit versions of Windows.

In 1998, AutoCAD 2000 brought many significant changes to the GUI. The most important of these changes was to create a new data structure called the Graphics Database (GD) object, which allowed users to work with more complex data types. For example, curves, dimensions, linetypes, and hatch patterns could now be stored in GD objects. The graph editor also received a major upgrade

Data exchange
AutoCAD supports the following protocols for file transfer:
CATIA File format (.caf) is a file format used to exchange CAD files between CATIA, Inventor, NX, SOLIDWORKS and other CAD programs. The file format was originally developed by Siemens for Siemens NX and later ported to the other CAD programs, and is also adopted as an exchange format in Enovia’s Extensible File Format.
STL (Standard Template Library) file format (stl file), which is based on the COLLADA/DAT file format, is a standard 3D modeling file format. It can be used to exchange CAD models between all major AutoCAD/CATIA/SOLIDWORKS/Siemens NX-based CAD programs. STL is sometimes used to interchange 3D models between non-CAD-based software such as FreeCAD, Sketchup, and LibreCAD, among others.
WMF is a format used to exchange CAD models between CAD programs based on the Microsoft Windows operating system. The format is also supported by Autodesk’s CAD-X products.
X3D is a format used to exchange 3D CAD models, available only in a subset of AutoCAD and Autodesk CAD software.
ACIS 3D is a CAD model format in which the geometry is stored in an STL file. It is based on the ACIS CAD model format.

In addition to these formats, AutoCAD supports the export of DWG files to Microsoft Excel, Hyper-V virtual machines, AutoLISP source code,.NET assembly code, and XML.

Raster image exchange

AutoCAD supports various raster image file formats, including BMP, RLE, TIFF, and PNG. The native image format for AutoCAD is DXF, but it supports more than the traditional palette and/or indexed color modes. More recently, it supports the full 8-bit color capability of the file format.

In addition to file-based, AutoCAD can also be used in a web browser with AJAX (Asynchronous JavaScript and XML) to easily share drawings.

Open source and free
In addition to the original Windows version, several AutoCAD variations are available as open-source products. They include:
AutoCAD LT, a stripped-down version of AutoCAD, that is available for Windows XP, Windows Vista, and Windows

11. You are done.It is often desirable to share information between mobile devices. For example, it may be desirable to use a set of mobile devices to capture images. Using a set of mobile devices allows for improved image capture as the user will have multiple devices capturing the image, and thus, should the user happen to capture the image at a bad angle, the image will be captured on more than one device.
Once the image is captured, it may be desirable to exchange the image among the devices. Some mobile devices may be equipped with a messaging system, while other mobile devices may be equipped with cameras. Thus, using the mobile devices to exchange the image may be desirable.Q:

Proving inequality with sinh

How to show that $sinh(x)+cosh(x) > 0$
Should I try with inequality and what I got is:
$\sinh(x)+cosh(x) > 0 \Rightarrow \frac{x}{x}+\frac{1}{x} > 0$
and I don’t know what to do next. Can you give me a hint?

$$\frac{\sinh x+\cosh x}{x}=\frac{\frac{e^x-e^{ -x}}{2}+\frac{e^x+e^{ -x}}{2}}{x}=\frac{e^x
