Once you get it Saravana, it's easy.

I found that there wasn't anything decent on the internet so I made a short video to explain it using animations.

Its very simple saravanan, Just imagine...
Take a reference of same image uploaded by Pradyamuna

The Object is placed between your EYE and Drafting Plane, that is 1st Angle
The Plane is placed between your EYE and Object, that is 3rd Angle,

Are you okay now????

While detailing the 2d drawing, is there any difference? or its just the placement in the quadrants?
