Creation of geometries by Coordinate system methods using AutoCad

• AIM :
• Create the geometries from P1 to P2 using all the coordinates system methods. By using the Line tool to create the geometries. use the circle tool in some cases .
• SOFTWARE USED :
• Autodesk autocad 2021
• PROCEDURE :
• first open the autocad software
• give command the software QNEW or go to the application menu and click the NEW option
• then click on ADVANCE SEETING
• select matric seeting
• unit in decimal having precision 0.0
• template :Acad.dwg
