Creating a Floor plan, Footing detail and Isometric view using AutoCad
AIM:
To create a Floor plan, Footing detail, and Isometric view using AutoCAD.
INTRODUCTION:
The main objective of this assignment is to get knowledge in various tools in AutoCAD like the rectangle, polylines, modification tools like copy, move, offset, and modes like snap mode and ortho mode. These tools will be understood by creating a footing detail, a two-bedroom building, the cross-section of a 2-bedroom building showing foundation details, and an isometric view of steps and gable wall.
