AutoCAD Free [Latest 2022]

In January 2000, AutoCAD Serial Key became available as a client application of the Autodesk Design Suite. Autodesk announced a full conversion of AutoCAD to this new environment in August 1999. The new design suite was dubbed AutoCAD LT. AutoCAD is available in several editions aimed at different market segments. The base product is AutoCAD; additional products include AutoCAD Architecture; AutoCAD LT Basic, which is intended for classroom and self-study; and AutoCAD LT Civil, Architectural, Landscape, Mechanical, Plumbing, Electrical and Fire Protection, and Structural, which are more complex products for professional use.

The application has been ported to the Z/OS, DEC Alpha, IRIX, HP-UX, and FreeBSD operating systems. In December 2002, Autodesk released AutoCAD R14, a major upgrade that included new tools for creating and manipulating geospatial data. The products’ capabilities are covered in the following sections.

Hands-on Exercise 2D: Understanding AutoCAD

To make the examples in this chapter more realistic, the first exercise on using the basic functions in the AutoCAD program will be of the most simple type.

Let’s start by exploring the following diagram:

Step 1: Start AutoCAD.

Step 2: Open a new drawing file.

Step 3: Display the Object Snap, Plan, Ortho, Level and other options, as shown in the following screenshot.

Step 4: Start creating the basic elements in the drawings.

Step 5: Save the file to your hard drive and close the application.

Using this simple drawing exercise, it will be easier to understand how to use the basic objects.

1. Create a new drawing object in the drawing window with dimensions: width: 600 pixels, height: 300 pixels
2. Switch to the viewport, set the active view to Drafting, choose Render Normal, set the rendering to AI 2.5, and set the render resolution to 150 DPI
3. Select the Drafting_View_Drafting_File.dwg drawing file, and open it in ACAD (If this file isn’t open, just double click it).
4. Insert a plane in the drawing by using the Drafting tool, set the properties to a width of 100, and set the color to 50% transparent.
5. Insert an XY coordinate plane
6. Insert a mirror line in the XY plane
7. Open the Drafting_View_Drafting_File.dwg file, and add a drawing object with dimensions 600 pixels by 300 pixels to the drawing.
8. In the Specify Settings dialog box, set the brush style to Solid, the angle of the brush to 15 degrees, the scale to 0.25, and the opacity to 90%.
9. Select the blue rectangle, and insert a small arrow in the center of the object. Set the scale to 0.3, and the opacity to 30%.
10. Select the rectangle again, and insert a curve at the center of the object. Use the handle tool, and rotate it slightly. Set the scale to 1, the angle to 20 degrees, and the opacity to 60%.
11. Select the new curve, and double-click it to bring up the Specify Points dialog box.
12. Set the vertical points to 1, and set the horizontal points to 3.
