Creation of geometries by Coordinate system methods using AutoCad

AIM:

To create the given geomwtries and trusses in AUTOCAD, using the different co-ordinates system method and the line and circle drawing tools

Geometries P-1 and P-2 drawn by using all coordinate system, and each of the remaing geometries are drawn using any one of the coordinate system or the ditect distance entry method.

INTRODUCTION:

Coordinate system: Coordinate system is a system wherw numbers are used to deternime the unique position of points and/or other geometric elements

The various coordinate systems are:

1. Absolute coordinate system: In this system all points are established at some distance in X & Y- axis from a common origin

2. Relative coordinate system : In this systen location of a relative coordinate is defined by its distance from a reference point. In AutoCAD,when using this syatem 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 rwspect to their preceding point. This system is further classified as-

• Relative rectangular coordinate system: It is a coordinate system that specifies each point by a pair of numerical coordinate in the X-axis and Y-axis. In this system the points succeeding the first distance(length) and angle of a particular point with respect to its previous point.
• Relative polar coordinate: This system specifies the distance and angle of a paticular point with respect to its previous point.In relativr polar coordinate syatem,points are established by typing '@distance<angle'{enter} in the command box

3. Direct distancr entry method: It is another popular method used for drawing diffrent shapes/geometries in AutoCAD. Direct distance entry method enables the user to draw an object by simply poninting thr cursor in the desired direction and entering the required diatance in command bar
