Creation of geometries by Coordinate system methods using AutoCad

1)P1:-

Aim:-

• Create the geometries of P1 drawing using all the coordinates system methods.

Introduction:-

There are four co-ordinate system in AutoCAD.

• Absolute Co-odinate system:-
• Absolute coordinates is distance or angle of axes relative to the origin of the coordinates. Absolute coordinate entry is the default. When drawing lines, AutoCAD is ready to place the next vertex wherever you tell it to go.
• Relative Co-odinate system:-
• A)Relative rectangular co-ordinates:- In this the distance or angle of axes relative to the last point. Remember to add @ before entering coordinate values, take @2, 3 for example, it shows the distance from the last point in the X-axis direction is 3 and in the Y-axis direction is 3.
• B)Relative Polar Co-odinate:- Polar coordinates are named for their “pole”; the reference point to start counting from, which is similar in concept to the origin. Polar coordinates employ one radial distance and one angle (by convention, the angle is measured counterclockwise from the x-axis). The angle signifies the direction, and the distance is how far to go in that direction from the pole.Polar coordinates in AutoCAD are given as R<Degrees, where:
  • “R” is the radial distance
  • “<” is the less than sign (but in this case represents the angle)
  • “Degrees” is the value of the angle in degrees
  Both absolute coordinates and relative coordinates can be entered, but @ needs to be added when entering relative coordinates such as @ 10< 45.
• Direct distance entry:- This is the simple method of drawing. With direct distance entry, we can quickly specify a point relative to the last point you entered. At any prompt for a point location, move the cursor first to specify the direction, and then enter a numeric distance.

Procedure:-

1)Absolute Co-ordinate system:-

• On opening the AutoCAD software, setup the units to imperial template and decimal system to 0.00. Set the limits in the command tab using 'Limits' before drafting.
• Steps:-
