    Hi Imran daud shah,

    We can get AZ1 and AZ2 Azimuth direction from two ways.

    First way -  AZ1 and AZ2 is perpendicular by center point (O) to P1 line. So we will know AZ1 and AZ2 azimuth direction.

    Second way - If you using AUTO Cad , can measure angle direct from North line 0 degree to AZ1 and AZ2 line.

  • yes bus sir how we measure with out auto and any formula or any tips
  • Land Surveyor
    U have to measure it in autocadd. Draw a line from p1 to north direction . And then check the angle between north line and arc line. That will be ur az1z same like u can measure az2
  • Can you help me how to measure
  • Land Surveyor
    Thnx a lot mr. Kyaw min tun.... i got it. I will check it. And mr imran doud shah thi az1 and az2 will measured from north.
