Creation of geometries by Coordinate system methods using AutoCad
Question :- create the geometric from P1 and P2 using all the coordinates system methods . you need to use the line tool to
create the geometrics where required you need to use the circle point .
Note :- Use the imperial template and the decimal Units to draft the features . dimension are there for referance
ANS:-
AIM :- To create the geometric of the given drawings using all the coordiates system methods using line tools and circle .
Introduction :-
- coordinate systems :- there are four methods of coordintes system
1) Absolute coordintes system : Absolute coordinates based on the UCS origin (0,0) which is the intersection of the X and Y axes . Use absolute coordinates when you know the precise X and Y value of the point .
2) Relative rectangular coordinates system : relative coordinates are location defined by their distance from a refernce
point. to specify relative coordinates , preced the coordinates value with an @ sign . for example , entering @3,4
specifies point 3 units along X axis and 4 units along Y axis the last point specified .
3) polar coordinates system : To specify relative coordintes .preceds the coordinates value with an @ sign . for
example entering @1<45 specifies a point at a distance of 1 unit from the last point at an angle of 45 degree from
X axis
4) direct distance sysytem :- this is most common and easiest system used for drafting in Auto CAD . value are
provided through keyboard and direction is guided through the mouse .

Question : - Draw the profile and trusses using any coordinates system methods . the dimension are there are referance
ANS : -
AIM :- to create geometric of the given profile using relative coordinates system method & truss using absolute coordinates
system .
INTRODUCTION :-
Absolute coordinates uses the cartesian system to specify a position in the X ,Y , Z axes to locate a point
from the origin ( 0,0 ) point . to locate a point using the Absolute coordinates system , type the X-value
Y- value , and if needed , the Z-value separated by commas .
_ Relative polar coordinates system is used when we need to draw a new point of specified distance away
from the current point at a specified angle from the origin . using polar coordinates , point entered by
typing @distance
