Lesson 1 > 2 > Drawing Commands in AutoCAD

Introduction

AutoCAD has its variety of commands. Proper use of commands results in effective and fast completion of the drawing. So, it is necessary to know all the commands. The commands given to the computer should be in the proper sequence or it may lack the performance of the computer. Generally people says that AutoCAD ruins the performance the reason behind it is we don't give the commands to the computer in the proper sequence. The commands given to the computer must be in the proper sequence and effective. e.g. for making a square instead of using line command using the rectangle is always a better choice. It helps us to avoid the wastage of time and the work can be done effectively.

Drawing commands

There are lot's of commands inside AutoCAD but now we will mainly focus on the Drawing commands. We will try to make new drawing objects. some of the basic drawing commands are:

Icon	Function	Command	Location	Result
	Line	L / Line	Home > Draw > Line	To draw the straight line segments.
	Polyline	_pline	Home > Draw > PolyLine	It is a connected segments of line to create a single planer object.
	Rectangle	_rectang	Home > Draw > Rectangle	To draw the rectangular polyline.
	Circle	_circle	Home > Draw > Circle	Create a circle using a center point and radius.
	Arc	arc / E	Home > Draw > Arc [center/start/end]	Creates an arc using 3 points.
	Erase	_erase	Home > Modify > Erase	To remove the object.
	Undo	CTRL + Z	Quick Access Toolbar > Undo	Removes the recent action.

With the help of above table you must have understood the various drawing commands in AutoCAD and their results now we will try to make the following drawing using AutoCAD.

Figure 1.2.1 : Drawing Commands Assignment

Steps:

1. Create a new drawing document from the application menu. by clicking on  new document. or just use CTRL + N
2.  A new dialogue box will appear having lot's of drawing formats. From that select the acad.dwt template.

   

   Figure 1.2.2 Dialogue of template Selection.

   
   
3. Now, you have created your document. Now all you have to do is just draw some of the basic stuff the same way we do inside the paint.
4. Initially we will try to draw the rectangle given above. We know that the starting and ending point of rectangle is (2,2) so select the ractangle from the HOME > DRAW > RECTANGLE or use _rectang command in the command box.
5. Now the next thing it will ask you about the starting point. As we know our starting co-ordinate is (2,2) so just put "2" now press "," and again put "2".

   

   Figure 1.2.3 : Setting out 1st point of Rectangle

6. Now you will see the starting point is fixed on the working place now we have to provide the final co-ordinate. The same way we will provide the final co-ordinate which is (6,6) and press Enter will show you the formed rectangle.

   

   Figure 1.2.4 : Rectangle Formed with final co-ordinate

7. Now we have completed our rectangle now next thing we have to do is to draw a circle. First we look about the information of circle, for the circle we have got it's center point and it's diameter.
8. Try to make it yourself rather than following the steps. If you think that you can't then you can see the following hint.

Show me the hint

1. To draw the circle first click on the circle button from HOME > DRAW > CIRCLE or you can even use the command _circle .
2. The next thing you have to do is setup the central point of the circle. We know the central point of the circle. Provide them the same way as we provided with the rectangle.
3. Now you need to provide the radius. We know the diameter is 6, so provide the input of radius as 3 and here your circle is formed.
