One of the biggest things to consider when looking into the wonderful field of drafting is that every single company does things differently and that every type of drafting is also quite different. As an example, architectural drafting is mostly 2-D drawings with rendering done at the end. Architectural drafting is also more of a concept-type drawing. It is much easier to say I think this wall will look good here than it is to say this wall must go here in order to support the second or third stories of a building. When you look into civil drafting, you need to understand that the planes you will be drawing to are also going to be very different. Typically, architectural drafting is drawn to the inch, where as both mechanical drafting and civil drafting are typically drawn to the decimal of a foot. In architectural drafting, there are usually a lot of symbols that are prepared as BLOCKS that may be pasted right in the drawings, whereas in the other two types, everything is so specific that it must be drawn from scratch each time.
“Block” as mentioned above is a fairly common command in architectural drafting. You can key in the word and press enter to open the window that stores all of the pre-drawn images. Once you select the image you would like to insert, simply double-click and the window will close, leaving the block itself visible. Place the block on the drawing by single-clicking the spot you’d like it to be.
“Line” is most likely the most common command you will ever use in AutoCadd. Most of the time it is set as a default for the L key so you can simply key in the L and enter to start your line. After keying in L and enter, you simply key in where you would like to start your line per the coordinates, or clicking the place you would like to start it. If you do not choose either of these options the line will automatically start at (0,0).
“Circle” is possibly the second most common command for the AutoCadd Beginner. The default setting is typically for circle is C and the enter key. After that you need to choose where you would like the center of the circle to be placed. Once you have chosen where the center should be, it will prompt you to put in the dimensions for the circle. You have the option of choosing the length of either the radius or the diameter. The default setting is typically for the radius.
Another great command for the beginner is “Copy.” The short command for copy is usually defaulted as co and the enter key. You may select as many or as few items to copy as you would like by dragging the mouse over the items, or clicking on specific ones. Keep in mind when you drag the mouse, dragging it from the left to right will select everything the box touches, and dragging it from the right to left will only select the items that are completely within the box’s boundaries.
One of my favorite commands to simplify things was the “Mirror” command. By typing in “Mirror” any items you select will be mirrored at any angle you select. To select the angle at which you would like the items mirrored you can just click on the point between where you want the new image and where the original is currently placed, from there you can move the mouse around the screen to find the exact mirrored image placement. Once you have decided where to mirror the image, you will be asked if you would like to delete the original image, here you may key in a y for yes, or a n for no.
These are the basic commands to help you get started. With these few you can draw almost anything! As you become more comfortable, you can start trying different words to see if they too are simple commands. Odds are if you are trying to do something there is a command for it.
