Question 1: Drawing C1 figure in AutoCAD

Aim: To draw the figure C1 of a C.S. of load bearing wall over spread footing

Introduction

Wall footing is a type of footing which is used to support walls, both structural and non-structural. This footing takes load from walls of structure and transfer the loads to the soil below. The load is transferred such that the load bearing capacity of the soil does not get reduced. It also maintains sufficient safety against the overturning and sliding and also avoids excessive settlement.

Question 6: Drawing C6 figure in AutoCAD

Aim: To draw the figure C6 of Isometric view of Gable Wall

Introduction:

A wall with triangular portion between the intersecting edges of roof pitches is called gable wall. The shape of the gable and how it is detailed depends on the structural system used, which reflects climate, material availability, and aesthetic concerns. The combination of wall and the gable at the top is referred to as the gable wall or gable end. While a front-gabled building faces the street with its gable, a side-gabled building faces it with its gutter, meaning the ridge is parallel to the street.
