Creation of geometries by Coordinate system methods using AutoCad

AIM- Create the geometry of given pictures in AutoCAD using all the coordinates system methods.

Introduction to Coordinate System :-

There are Four AutoCAD coordinates system :-

1. Absolute Coordinate System
2. Relative Rectangular Coordinate System
3. Relative Polar Coordinate System
4. Direct Distance Entry

Absolute Coordinates :-

• In Absolute Coordinate System, all input points specify in the drawing are with respect to origin (0,0).
• Absolute coordinates 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. As an example, in a CAD program you could draw a line using absolute coordinates. To do this start by entering the (x,y) value of your origin point

Relative Coordinates :-

• In Relative Rectangular Coordinate System, First point is entered with respect to origin (0,0) and all next points can be entered by specifying the next coordinate with respect to the first point.
• The Relative Coordinate started with symbol “@”. In Relative Rectangular Coordinate System, points entered by typing"@x,y" and press Enter.

Polar Coordinates :-

• Polar coordinates used when we need to draw the next points at a specify angle.
• Polar coordinates system in AutoCAD specifies distance length at an angle.
• In Relative Polar Coordinate System, points entered by typing "@distance<angle" and press Enter.

Direct Distance Entry :-

• It is the simple method of drawing.
• Direct distance entry enables to draw an object by pointing in a particular direction with the cursor and entering a distance at the Command Box.
• First points is entered with respect to origin (0,0) and then the cursor is move in the particular direction and distance is entered at Command Box.
