Creation of geometries by Coordinate system methods using AutoCad

GGaurang Chavan28 Aug 2022

AIM:

(A) Create the geometries from P1 to P2 using all the coordinates system methods. And we need to use line tool, and find the missing dimensions.
(B) Civil related problems- Draw the profile and the trusses using any coordinate system methods. The dimensions are there for references.
Introduction:
Before going to the drawing we should know about the coordinates systerns.
In Autocad there are two coordinate systems: Cartesian and polar.
To these coordinate systems the absolute and relative coordinates of Autocad as are applicable.

Coordinate Systems: Coordinate system is a system where numbers are used to determine the unique position of points and/or other geometric elements.

Also coordinates in AutoCAD can be set by mouse, input (setting) the values of coordinates in the command line and enter coordinates using dynamic input.
There are three types of co-ordinate systems.
1. Absolute coordinate systems
2. Relative coordinate systems
3. Relative rectangular coordinates
4. Relative polar coordinates
5. Direct distance entry

1. Absolute Coordinate System: In this system all points are established at some distance in the x & y-axis (sometimes z-axis) from a common origin (usually 0,0).

2. Relative Coordinate System: The location of a Relative coordinate is defined by its distance from a reference point. In AutoCAD, when using this system the first point of the drawing/geometry is always absolute, i.e. it is established with respect to origin (0.0) and then all the successive positions are established with respect to their preceding point. This system is further classified as

3. Relative rectangular coordinates: It is a coordinate system that specifies each point by a pair of numerical coordinates in the x-axis and y-axis. In this system the points succeeding the first point are typed in as '@x,y' in the command line.

4. Relative polar coordinates: This system specifies the distance (length) and angle of a particular point with respect to its previous point. In Relative polar coordinate system, points are established by typing @distance
