Jagadeep.M.M

AIM:

1. Create the geometries from P1 to P2 using all the coordinates system methods.
2. Create the geometries from P4 to P10 using any one coordinates systeem methods.
3. Draw the profile and the trusses using any coordinate system methods.

Introduction:

Coordinate system:

There are 3 coordinate systems

1. Absolute coordinate system:Plotting point with respect to origin.
2. Relative coordinate system:Plotting next point with respect to previous point.

Relative rectangular coordinate system

Relative polar coordinate system

3. Direct distance entry system:Plotting next point by positioning the cursor in desired direction & mentioning the distance directly.
