Introduction to AutoCAD Alf Yarwood. Chapter 19 Exercise 1. 1. Open AutoCAD with a double-click on its shortcut icon in the Windows desktop. 2. are bringing a PDF into AutoCAD, there are significant enhancements to the underlay feature which makes for quicker, more fluid panning. AutoCAD is helping. and Tricks for Using AutoCAD When you load AutoCAD you will be asked to .. finished. Be sure to select DWG to. irkeraslajour.ga3 in the Plot command . You can find similar options on the . even more in-depth introduction to the.
There are many more options regarding units so you can select then according to your requirement. Divide the Commands in three categories to learn more easily. By default unit is inch. Coordinates can be given by clicking the courser or by putting the values x,y in the command window. This is the sample drawing including only line command with annotation.
You can select Ortho Mode for your easiness to draw perpendicular lines After selecting the starting coordinates move the courser to right side towards which you have to draw the line and upside of the line there is a digital value which indicates the length of line. You can put it 20 by numerical buttons of laptop or desktop and then press enter button. There is also indication of angle of line on the courser from the horizontal line.
Put the value of 10 and press enter to add the line. Now move your courser to the starting point to end the required drawing. You can also see the angle of your drawing which is being drawn in this step. Here it is o. After clicking the start point which is actually end point of drawing. Finally you will get the drawing in this condition. First try the following drawing. The beginning steps are the same to open the new drawing window.
Now with the help of courser click on drawing window at start point which is selected by you any point in drawing window. A lot of inexperienced users approach the program as if it was MS Paint for engineers, and end up creating horribly thought out and disorganized drawings that can cause no end of strife and frustration for those who may later be required to work with the files.
Not only can badly created drawings cause ulcers to other AutoCAD users, they make it a lot easier for design flaws to sneak into the process. A little bit of pre-planning and some attention to good drafting practice might be the difference between a painless efficient project and a messy expensive rebuild.
The most important thing to understand is that AutoCAD does not, strictly speaking, create "drawings" in the classic sense of the word. The user should not consider themself to be making pictures or creating images. A much more useful and accurate way of thinking about an AutoCAD drawing file is as being a database full of information. The AutoCAD program allows the user to view and edit this information through a graphical interface. Thus, when drawing a line between two points, realize that you are entering two coordinates into your database.
So if you want a line that links the points , and , , then those should be the values you use. Do not, under any circumstances, just scribble down a line in a place that "looks" right.
What kind of database user are you, to be inserting You can use the "Object Snaps" feature to make this work properly, and there is no excuse for creating drawings that contain elements that look like they line up until you zoom in to micrometer scales and discover why those polylines weren't joining correctly or those hatches weren't applying properly etc.
It is through the layers window that all data is organised and controlled.
A layer can be thought of as being a transparent sheet overlaying the drawing board. You can have as many as you wish. It is extremely useful to separate as much data as possible onto separate layers.
It allows you to have numerous "drawings" all existing together in the one file. When a layer is "turned off" all the information that was on that layer becomes invisible.
For a new drawing, the only layer available is the layer 0. This is a special layer which is required in all drawings.
It is bad drawing practice to create linework on this layer. It should be used only for creating the components of blocks and inserting xrefs. More on these later. New layers can be created by hitting the "New Layer" button. By default, Autocad will name new layers "Layer1", "Layer2" etc.
It is advisable to rename the layer to match the content that will be drawn on it, e. ByLayer[ edit ] An extremely important aspect of the layers window are the columns for Color, Linetype and Lineweight. Next you might select the color value of this layer and set it to Blue.
Upon hitting OK and returning to the drawing, you might start constructing linework.
You will notice that the layers toolbar has several dropdown boxes in it, again showing color, linetype and lineweight. If all is well in the world, the words ByLayer should be written in all these boxes. It is possible to set the color of an object to something other than ByLayer, by selecting the object and than opening the color dropdown box on the Layers toolbar.
This is very rarely recommended though. Think about it. Now suppose that there is one particular pipe that you want to appear green, because it is made of steel instead of plastic or something. The cheap and lazy option is to just change that objects color to green, but this means that you have given up some control over that line, because now you can no longer edit its color through the layers window.
A good rule to bear in mind is, if something is different enough to deserve its own color, then it certainly deserves its own layer.
Linetypes[ edit ] Linetypes are a method of defining the pattern in which a particular line will print out, whether it be dashed or dotted or numerous other styles. The default setting is called Continuous, which just means a standard uninterrupted line.
However, cases will arise, in particular when printing in black and white, in which it will be necessary to differentiate between different pieces of linework. Defining linetype works exactly the same way as for color.
It can be changed individually on an object by object basis, but it is almost always preferable to leave everything set to ByLayer and adjust the settings through the layers window. To make others available, double click on Continuous in the layers window.
The box that opens will have an option to "Load".
