Creation of geometries by Coordinate system methods using AutoCad
AIM :
(A) Create the geometries from P1 to P8 using all the coordinates system methods. And we need to use line tool, and finish the missing dimensions.
(B) Civil related problems-Draw the profile and trusses using any coordinate system methods. The dimensions are there for reference.
INTRODUCTION :
Before going to drawing we should know about the coordinate systems.
In Autocad there are two coordinates systems : Cartesian and polar.
To these coordinates systems the absolute and relative coordinates of autocad are applicable.
Also coordinates in autoCAD can be set by mouse, input the values of coordinates in the command line and enter coordinates using dynamic input.
There are 3 types of co-ordinate systems
- Absolute coordinate systems
- Relative coordinate systems
- Relative rectangular coordinates
- Relative polar coordinates
3. Direct distance entry
commands used :
1. line command
2. Dimlinear command
3. Text command
4. Circle command
(A) Create the geometries from P1 to P8 using all the coordinates system methods. And we need to use line tool, and find the missing dimensions
Absolute coordinate system :
Below we have drawn the p1 drawing using the absolute coordinate system,
P2 DRAWING : Using absolute coordinate system, based on the graphical values of coordinates
P3 DRAWING : Using absolute coordinate system, based on the graphical values of coordinates
P4 DRAWING : Using absolute coordinate system, based on the graphical values of coordinates
P5 DRAWING : Using absolute coordinate system, based on the graphical values of coordinates
P6 DRAWING : Using absolute coordinate system, based on the graphical values of coordinates
P7 DRAWING : Using absolute coordinate system, based on the graphical values of coordinates
P8 DRAWING : Using absolute coordinate system, based on the graphical values of coordinates
Relative rectangular coordinate system:
P1 DRAWING
here
below we have drawn the p1 drawing using the relative rectangular coordinate system,
the co-ordinate are (2,1) (@6,0) (@0,1) (@-5,0) (@0,4) (@5,0) (@0,1) (@-6,0)
p2 drawing:
the coordinates are (2,1) (@3,0) (@0,4) (@1,0) (@0,-4) (@3,0) (@-2,7) (@-3,0) (@-2,-7)
p4 drawing
the coordinates are (2,1 ) (@1,0) (@0,7) (@5,0) (@0,-6) (@-3,0) (@0,-1) (@4,0) (@0,8) (@-7,0) (@0,-8)
p5 drawing :
the drawing coordinates are (2,1) (@8,0) (@0,6) (@-8,0) (@0,-6) (3,5) (@2,0) (@0-3) (@-2,0) (@0,3)
p6 drawing :
the coordinates are (0,0) (@0,2) (@4,0) (@-3,0) (0,2 ) (@8,0) (@0,-2) (@-3,0) (@0,-4) (4,0) (@0,-2) (@-10,0} in sequence
p7 drawing :
the coordinates are (1,1) (@5,0) (@0,2) (@-3,0) (@0,-1) (-1,0) (@0,2) (@3,0) (@0,2) (@-4,2) (@0,-7)
p8 drawing :
the coordinates are (1,1) (@2,0) (@0,3) (@3,0) (@0,4) (-5,0) (@0,-7) (@2,7) (@3,0) (@0,-2) (@-3,0) (@0,2)
Relative Polar co-ordinate system:
p1 drawing we drawn using relative polar coordiante system
p2 drawing we drawn using relative polar coordiante system
p3 drawing we drawn using relative polar coordiante system
p4 drawing we drawn using relative polar coordiante system
p5 drawing we drawn using relative polar coordiante system
p6 drawing we drawn using relative polar coordiante system
p7 drawing we drawn using relative polar coordiante system
p8 drawing we drawn using relative polar coordiante system
DIRECT DISTANCE ENTRY :
The direct distance entry coordinate system which the drawing will be drawn with the direction and dimensions and that should be drawn,.
p1 drawing using direct distance measurements
p2 drawing using direct distance measurements
p3 drawing using direct distance measurements
p4 drawing using direct distance measurements
p5 drawing using direct distance measurements
p7 drawing using direct distance measurements
B) Civil related problems draw the profile and trusses using any coordinate system methods, the dimensions
are there for reference.
- Now the given diagrams are drawn using absolute coordinate system
PROFILE WOOD:
QUEEN POST TRUSSES:
MONO PITCH :
RESULT :
- The dimensions are clearly mentioned in all drawings and missing dimensions are also written.
- using all the coordinate system all the drawings are clearly drawn from p1 to p8 drawings
- the profile trusses are drawn sucessfully by using the absolute coordinate system .
