Equipped with the right applications, a computer can be of great help in virtually any domain of activity. When it comes to designing and precision, no other tool is as accurate as a computer. Moreover, specialized applications such as AutoCAD give you the possibility to design nearly anything ranging from art, to complex mechanical parts or even buildings.
Suitable for business environments and experienced users
After a decent amount of time spent installing the application on your system, you are ready to fire it up. Thanks to the office suite like interface, all of its features are cleverly organized in categories. At a first look, it looks easy enough to use, but the abundance of features it comes equipped with leaves room for second thoughts.
Create 2D and 3D objects
You can make use of basic geometrical shapes to define your objects, as well as draw custom ones. Needless to say that you can take advantage of a multitude of tools that aim to enhance precision. A grid can be enabled so that you can easily snap elements, as well as adding anchor points to fully customize shapes.
With a little imagination and patience on your behalf, nearly anything can be achieved. Available tools allow you to create 3D objects from scratch and have them fully enhanced with high-quality textures. A powerful navigation pane is put at your disposal so that you can carefully position the camera to get a clearer view of the area of interest.
Various export possibilities
Similar to a modern web browser, each project is displayed in its own tab. This comes in handy, especially for comparison views. Moreover, layouts and layers also play important roles, as it makes objects handling a little easier.
Sine the application is not the easiest to carry around, requiring a slightly sophisticated machine to properly run, there are several export options put at your disposal so that the projects itself can be moved around.
Aside from the application specific format, you can save as an image file of multiple types, PDF, FBX and a few more. Additionally, it can be sent via email, directly printed out on a sheet of paper, or even sent to a 3D printing service, if available.
To end with
All in all, AutoCAD remains one of the top applications used by professionals to achieve great precision with projects of nearly any type. It encourages usage with incredible offers for student licenses so you get acquainted with its abundance of features early on. A lot can be said about what it can and can't do, but the true surprise lies in discovering it step-by-step.







AutoCAD 20.0 (Updated 2022)

AutoCAD is the world’s most widely used computer-aided design (CAD) and drafting software. Released in 1982, AutoCAD is available as a standalone desktop app or as part of the larger AutoCAD LT suite. AutoCAD allows users to create two-dimensional (2D) and three-dimensional (3D) drawings, with models that can be used to generate solid, surface, and outline views. In addition, AutoCAD includes extensive documentation and a library of thousands of different predefined 3D shapes and objects, as well as other features such as parametric drawing, graphics viewing, an interactive 2D layer, a measuring tool, and a graticule.

As of release 2015 (version 2016), Autodesk released the “AutoCAD Architecture” which allows customers to customize the UI in an AutoCAD environment.


AutoCAD has been a commercial product since the original release of AutoCAD in 1989. AutoCAD is often used by architects and contractors, industrial designers and engineers, and graphics artists.

AutoCAD is available in many different versions:
AutoCAD LT (basic AutoCAD product)
AutoCAD LT for Windows (has full AutoCAD functionality for both Windows and Mac OS X)
AutoCAD LT for Windows 3D
AutoCAD for Windows
AutoCAD for Windows 3D
AutoCAD for Windows for Schools
AutoCAD for Small Business

AutoCAD LT was available for Macintosh computers in 1996, but was discontinued in 2015. The only AutoCAD LT-based version, AutoCAD LT for Windows, is available for both Windows and Mac.

AutoCAD LT for Windows 3D and AutoCAD for Windows 3D are the same product, which are available only for the Windows operating system. They were released in late 2002 as part of the Windows XP release. AutoCAD LT was discontinued on May 31, 2015.

AutoCAD LT for Windows 3D is also available on Windows 7 and Windows 8.

AutoCAD Architecture, a third-party add-on, was released for AutoCAD LT and AutoCAD 2017 on April 28, 2014 and will be available for AutoCAD 2016 in the same release. AutoCAD LT for Windows 3D has been discontinued.

The LT-based (or legacy) AutoCAD is available for the Mac OS operating systems since 2014, as well as Microsoft Windows 7 and Microsoft Windows 8. AutoCAD LT for Windows and AutoCAD for Windows were discontinued on May 31, 2015.


AutoCAD was first developed by Mechanical System Laboratories (MSL), and was released as the MSL AutoCAD in 1989. It was licensed to Alias Systems, Inc. in 1994. Then it was sold to Autodesk in 1997, which has continued the product through many successive product releases.

Extract data from multiple tables into 1 ListView

I am trying to extract data from multiple tables into 1 ListView.
so far i have tried the following codes :
string connectionString = “Data Source=.; Integrated Security=True; MultipleActiveResultSets=True”;

MySqlConnection connection = new MySqlConnection(connectionString);

MySqlCommand command = connection.CreateCommand();

command.CommandText = “SELECT * FROM empinfo”;

MySqlDataReader reader = command.ExecuteReader();

while (reader.Read())
ListViewItem item = new ListViewItem();
item.Text = reader[“empno”].ToString();
