Hi guys, here is the remaining part of Autocad Tutorial for Beginners.
It is better and professional practice to work in layers. Layers are actually groups. You give a separate name to each group (layer) for example walls, doors, windows, sanitary fittings etc. For each layer, there are layers properties like color, line type, line weight plot style etc. These properties distinguish every layer from others. You feel convenience in studying the drawings. The most important advantage of layers is that if you want some amendment in all the walls or all the doors, you don’t have to do it one by one, just go to the layer properties and change the properties according to requirement. The amendments will automatically be applied to whole group (layer). Further while working on some specific task like studying the sanitary fittings of a structure you can turn all the other layers off to make the drawing less complex and easily understandable. Layers can also be locked if you don’t want to edit those specific layers further.
Click Layer tab from tool bar or type “LA” in the command area and press enter.
Click “New” for creating layer. Type the name of the layer e.g Walls. Click “Color” for color change. Click “Line Type” tab if you want to change the line type. There are following line types and many other as well:
Click on “Load” and then select your required line type. Click on “Line Weight” if you wish to change the line thickness.
It is used :
1. To draw horizontal, vertical or angular lines.
2. To draw offsets and projections.
3. To check a certain line if it is truly horizontal or vertical or not.
4. To bisect an angle.
For construction line, type “XL” in the command area. Type “H” for horizontal line or “V” for vertical line and press enter. It will produce a line of infinite length. Now you can use it for any purpose like checking any line in your drawing etc.
If you want an angular line, type “XL” and then type “A” for angle. Enter the angle value ad press enter. Here you can also press R to use a line as a reference.
This command is used to match the properties of any object with the properties of any other object (in a different layer) you desire. In other words, this command is used to transfer the properties of an object selected to any object selected. For this, type “MA” and press enter. Click the source object and then click the target object.
Any object can also be moved into a layer by selecting the object (by making window) and then click on the arrow as shown in the figure and select the layer in which you want to move the object.
Go to from menu bar Format→Dimension Style.
A dialog Box will appear named “Dimension style Manager”.
Click on “New”. Another dialog box will appear.
Type the Style Name e.g ABC and click continue.
Another dialog box will appear.
Here you can set the dimensions settings as your requirement.
To view the dimension of a line (whose dimension is not shown) go to from menu bar Dimension→Quick Dimension. Now click the starting point and end point of the line and drag to a small distance and click. It will give you the dimension.
Another method for knowing the length of a line (if you just wish to know the length without displaying on the drawing) is:
Type “di” in the command area and press enter. Then click the starting and end point of the line, it will give you the distance in the command area.
If you wish to calculate the AREA of a closed figure, type “area” in the command area and click on the corner points of the area and close the figure by again clicking on the first point. It will give you the area in the command area.
This command is used to hatch the areas in your drawing. Its requirement is that the boundary of the area to be hatched should be closed.
Click Hatch from the draw tool bar or type “H” in the command area and press enter. This dialog box will appear.
Select the “pattern” and “scale” of hatch. Then click “Pick Points” and click inside the area you want to hatch in your drawing. Then press “enter”.
Keep in mind that whole boundary of the area should be visible on the screen.
Click Rotate from the modify tool bar or type “RO” and press enter. Select object you want to rotate and select base point from where you want to rotate.
This command is used to join two non-parallel lines. At any corner, if there is some gap then this command is very useful.
Click Fillet from the modify tool bar or type “F” in the command area and press enter. Now type “R” for radius and press enter. Then click both the lines to be joined one by one and press enter.
To stretch any object according to the requirement on the drawing, you can use this command.
Click Stretch from the modify toolbar or type “S” in the command area and press enter. Select the portion you want to move by reverse window. Pick point and give direction where you want to move. Type the distance in the command area.
This command is used to create an identical copy of the object in the drawing.
Click Mirror from the modify tool bar or type “MI” and press enter. Select object you want to mirror. Define source point. Select second point and type “N” in the command area and press enter.
Array command creates multiple copies in a definite chosen pattern.
Click Array from modify tool bar or type “AR” in the command area and press enter. A dialog box will appear.
Suppose you want from this dot to .
Type in Row “1”
Type in Column “8”
Type in column offset “9”
Type in Row Offset “0”
Type in angle “0”
Select object and click ok.
How to draw an arrow:
Type “PL” in the command area and press enter. Specify base point. Type “W” and press enter. Type “0” as starting point and press enter. Then type 3” as endpoint. Specify direction and type 9”. The length of the arrow is three times that of its width. Press Escape. Use line command to make line ahead.
Click Quick Leader from Dimension Tool Bar. To change the size of arrow click properties. Go to bottom “Line and arrow” tab. Change the scale.
With the help of “Quick Leader” you can mould arrow lines to different lines.
Now you should be able to draw the following drawing.
How much you learn and expertise in any field depends upon how much time you spend in practicing. It is said that “Practice makes a man perfect”. Make this aim in your life and go ahead. Success will be at your doorstep. With Best Wishes…
