Creating a Floor plan, Footing detail and Isometric view using AutoCad
Aim: To Creating a Floor plan, Footing detail and Isometric view using AutoCad
Introduction: AutoCadd software offers soo many commands and have many features like camphering the rectangle, fillet rectangle, creating offset, dimension, ortho mode, moving, copying, creating mirror image, using isometeric mode, etc thus making the work easy, thus reduces the time of designing.
