Creation of geometries by Coordinate system methods using AutoCad
Ans
AIM
1.To create the geometries from P1 to P2 using all the coordinates system methods and use the Line tool to create the geometries.
2.Civil-related problems - Draw the profile and trusses using coordinate system methods. The dimensions are used for references.
INTRODUCTION
In AutoCAD, there are two coordinate system
Cartesian
Polar
To these coordinate systems, Absolute and relative coordinate systems are applicable.
Also coordinates in AutoCAD can be set, input the value of coordinates in the command line and enter coordinates using dynamic input.
There are three types of coordinate system.
1.Absolute coordinate system
2.Relative coordinate system
3.Relative rectangular coordinate system
4.Relative polar coordinate system
5.Direct distance entry
COMMANDS USED
1.Dimlinear command
2.Line command
3.Text command
4.Circle command
PROCEDURE:
1)Create the geometries from P1 to P2 using all the coordinates system methods and we need to use line tool and should find missing dimensions.
A)Absolute coordinate system:
P1 DRAWING:
P2 DRAWING
P3 DRAWING
P4 DRAWING
P5 DRAWING
P6 DRAWING
P7 DRAWING
P8 DRAWING
B)RELATIVE RECTANGULAR COORDINATE SYSTEM:
P1 DRAWING
The coordinates are (2,1),(@6,0)(@0,1)(@-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)
P3 DRAWING
The coordinates are (2,1)(@1,0)(@0,4)(@2,-2)(@0,-4)(@1,0)(@0,7)(@-2,-3)(@2,-3)(@-1,0)(@0,-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 coordinates are (2,1)(@8,0)(@0,-6)(3,5)(@2,0)(@0,-3)(@-2,0)(@0,3)(6,5)(@2,0)(@0,-3)(@-2,0(@0,3)
P6 DRAWING
The coordinates are (0,0)(@0,2)(@4,0)(@0,4)(@-3,0)(0,2)(@8,0)(@0,-2)(@-3,0)(@0,-4)(4,0)(@0,-2)(@-10,0)
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)

DIRECT DISTANCE ENTRY:
In direct distance entry the drawing will be drawn with the direct dimensions.

2.Civil Related Problems
Draw the profile and the trusses using any coordinate system methods. The dimensions are there for references.
PROFILE WOOD
QUEEN POST TRUSS
MONO PITCH
RESULT:
- The geometries are mentioned in all the drawings.Missing dimensions are also written
- Using all the coordinate systems all the drawings are drawn from P1 to P8 drawing.
- The Profile and Trusses are drawn successfully using the Absolute Coordinate method.
