What is the initial learning CAD essentials, hoping to learn more, please give …

1.Learning CAD must find one more use of books, I suggest you use self-study method:Think about what kind to use graphical CAD drawing, according to this graphic to learn the knowledge, again, does not require all, beginners can only learn the basic commands operations:for example, line, polyline, circle, rectangle, insert text, set layer, a simple standard, copy, move, cut, extend, offset, mirror, these basic graphics commands in general Drawing has been good enough to these commands is based upon proficiency, go .2 of other orders.a simple example of a command:Insert Line:1 Right-click the command line menu bar, then click on the screen that starting point to determine a straight line, when you move the mouse to move again after about, which is to determine the direction of the line, right on your mobile, that the way forward for the right line, then simply click on the screen a little on the an entire line can be drawn (or the command line enter a value such as 1000 is that you draw a straight line length of 1 meter CAD explain the way the default metric in millimeters) .3.strongly recommend that you use AutoCAD2004, Because this software is the family of the most widely used software in a, the major design institutes and construction units in the widely used and more suitable for beginners applications .4.strongly suggest that you download a video tutorial, since the books are difficult to understand, after all, more rigid video tutorial illustrations, should be more applicable.video tutorials, not necessarily have to be a 2004 edition, as a series of CAD software, although every year but the basic commands in the update will not change.

Thank you for your suggestions, thank you

CAD is the most accurate, and make all preparations before the drawing, such as setting different layers, adjustment changes ……and more thoughtful in to see more and more practice

added is more than the next practice, copy of some standard graph.remember to norms develop a good habit.the other is to read more of my son to take it.in accordance with the specifications ..hope to help you ..
