Line In Absolute Coordinate System - Autocad Coordinate System
In this video we will see that how to draw line using co-ordinates system and learn more about Autocad Coordinate system.
We have basically three method for Autocad Coordinate System.
Types of Coordinate System in Autocad
- Absolute Coordinate System :- (X,Y)
- Relative Rectangular Coordinate System :- (@ X,Y)
- Relative Polar Coordinate System :- (@ DISTANCE < ANGLE)
1. Abosolute Coordinate System
First we will see that what is Absolute co-ordinate system. In this system we will need to provide two values ie. X and Y where X represents Horizontal distance, while Y represents Vertical distance. Now we will select line command and specify the first point as 0,0 and then next point as 10,0 and continue our line as below specified points -
N.P.(Next point) 10,4
N.P. 7,4
N.P. 7,8
N.P. 4,8
N.P. 4,12
N.P. 0,12
N.P. 0,0
So this will create our required figure and in this way we can draw our line using absolute co-ordinate system.
The disadvantage of this method is that feature were co-ordinate we take it should start from 0,0 origin.
2. Relative Rectangular co-ordinate system
The next method is Relative Rectangular co-ordinate system. In this method if we are going to horizontal right side then it will be positive otherwise negative, and if we are moving upwards in vertical side then it will be positive otherwise negative.
For this method we will specify our points as,
F.P. - - -
N.P. @ 10,0
N.P. @ 0,4
N.P. @ -3,0
N.P. @ 0,4
N.P. @ -3,0
N.P. @ 0,4
N.P. @ -4,0
N.P. @ 0,-12
So this will create our required figure and in this way we can draw our line using relative rectangular method.
3. Relative Polar co-ordinate system
The next method which we are going to use is Relative Polar co-ordinate system. In this we will specify the distance first and then the angle of it seperated by '<' symbol. So for this method we will first select line and then press specify the following points in our command prompt with certain format,
F.P. - - -
N.P. @ 10<0
N.P. @ 4<90
N.P. @ 3<180
N.P. @ 4<90
N.P. @ 3<180
N.P. @ 4<90
N.P. @ 4<180
N.P. @ 12<270
So this will create our required figure and in this way we can draw our line using Relative Polar co-ordinate system.
