Creation of geometries by Coordinate system methods using AutoCad
AIM:
to creat the geometries from p1to p2 using all the cooridinate system methods to use the line tool and circle to create the geometries
TYPES OF COORDINATE SYSTEM:
1.Absolute coordinates
2. relative rectangular coordinates
3.relarive polar coordinates
4.direct distance entry
INTRODUCTION :
The main objective of this challenge is to gain knowledge on how to plot lines using the various coordinates system available.the challenge is divided into four parts and in each part certain figures are to be drawn using line and circle tool based on the four coordinate systems
in each part the figure will be drawn based on thatparticular coordinates system and the procedure for doing willbe given for all questions .
PART 1:ABSOLUTE COORDINATE SYSTEM:
Absolute coordinate refers to a cartesian system that uses x-axis ,y-axis and sometimes a z-axis to establish a point some distance from a common origin
PART2:RELATIVE RECTANGULAR COORDINATES
Relative coordinate are based on the last point entered. use relative coordinates when u know the location of a point relation to the previous point.
PART3:RELATIVE POLAR COORDINATE:
Relative coordinate are also based on the last point entered.use relative coordinates when u know the location of a point in relation to the previous point
PART4:DIRECT DISTANCE ENTRY
To locate the next point at a specified distance in the direction of your cursor
at the prompt to lacate a point ,enter a numeric value
PROCEDURE TO DRAW LINE:
LINE
To draw line simple lines oe series of lines segments access to command line by one way of the following
1.command line:line r L
2.Menu bar : draw - line
3. draw bar
4. tool palettes : draw- line
5.ribbon: home-draw panel -line
when excecut command line the program requiress specify first point ,display in command line
specify first point or (undo)
specify next point or (close/undo)
options:
*C: this option close series of lines , connect first point with last point by line.
*C:enter U for undo.AutoCAD backs up one segment , undoing it so that u can recreate it .
