Project 2: Creating a 3D rendered model for a Residential Building in AutoCad

AIM

To create a 3D rendered model for a residential building in AutoCad.

INTRODUCTION

A rendering is a particular view of a 3D model that has been converted into a realistic image. It includes basic lighting such as Gouraud shading as well as more sophisticated effects that simulate shadows, reflection and refraction.

In this project, a plan for G+1 residential building is drawn. The ground floor of the residential building is designed with a living room, 2 bedrooms with attached toilets, a dining, a kitchen, a staircase and a sitout. The first floor of the residential building is designed with a living room, 2 bedrooms with attached bathrooms, a terrace, a staircase and a balcony. All dimensions are in millimeters 'mm' in this project. All the details regarding the bulding is given below.
