Four Easy Steps For Beginners

 Step 1 : Learn the navigation (The AutoCAD Interface) ;

In fact,in CAD applications before starting to preparea design , you need to understand the interface. The drop-down menu list (that  is in the upper left corner), easy access to mess can be seen .

This feature of menu allows you to save Working files, open saved documents and complete a number of other important commands. You must also aware yourself with the Steering-Wheels tool, which zooms, orbits and pans your created image. Check out the InfoCenter, where you can perform keyword searches and obtain product announcements, as well as information from various RSS feeds. Look for additional assistance in navigating the AutoCAD interface (AutoCAD Tutorial ).

Step 2 : Master The Line Command ;

Now that you know where the various AutoCAD tools are located, it’s time to learn a few basic commands. The overarching AutoCAD function involves the line command. This allows you to form either a single straight line or a chain of lines. This command can be found on the draw toolbar or under the draw menu. You can learn about the shortcuts for accessing the line command in Autodesk Autocad.

Step 3 : Utilize Cartesian Coordinates ;

AutoCAD operates under a system of coordinates which, while initially confusing, ultimately provides for enhanced accuracy. If you’ve ever taken a pre-calculus course, you will immediately recognize the familiar Cartesian coordinates. And if you skipped pre-calc in high school or college, no worries —you should still be able to navigate this setup with little effort. You can see a thorough explanation of AutoCAD’s Cartesian coordinates in Learning AutoCAD 2014 Drawing Essentials.

Step 4 : Complete A 3 Point UCS Command ;

AutoCAD’s coordinate system is referred to as UCS, or User-Coordinate System. To operate the UCS, look in the toolbar for an icon featuring a small square with two attached arrows. You can also access the UCS function by visiting the pull-down menu and selecting the option marked ‘tools.’ Continue in the UCS menu to the option labeled ’3 Point.’ Here, you can select three separate coordinates in space and use them to form shapes. The first point, otherwise known as the origin, places the intended shape in a specific spot on the coordinate plane. Following shape placement, determine the size of the shape by designating coordinates on the X axis and the Y axis. Get additional specifications for 3D AutoCAD shapes in Learning AutoCAD – 3D Modeling And Rendering. In AutoCAD, a few simple commands allowyou to create a vast world of 2D and 3D designs. It’s worth taking a little time to master AutoCAD basics — the investment’s returns are beyond measure.

Absolute and Relative Coordinates

Coordinate	Interpretation
25,75	depends on context
@25,75	relative
#25,75	absolute

It used to be very simple. Enter a coordinate and AutoCAD interpreted it as an absolute coordinate. Enter a coordinate preceded by "@" (the at sign) and AutoCAD interpreted it as a relative coordinate. This simple rule changed when dynamic input was introduced and now the interpretation of coordinates is contextual. For example, when you draw a rectangle using RECTANG, the coordinate for the second point is interpreted as absolute with dynamic input turned off and as relative with dynamic input turned on. Really, try it and see.

Fortunately, there's a new coordinate prefix that forces an absolute coordinate, even when AutoCAD decides you want a relative one. Precede any coordinate with "#" (the hash sign) to force an absolute coordinate.
