AIM :

         TO DRAW THE 3D WIREFRAME MODEL OF A DROP COLUMN AS SHOWN FIGURE BY USING AUTOCAD TOOL

INTRODUCTION :

THE 3D MODEL GIVEN IS A DROP COLUMN USED FOR CONSTRUCTION OF FLAT SLABS.
A DROP COLUMN IS USED WHEN BEAM IS NOT REQUIRED IN THE DESIGN.
DROP IS A PART OF THE SLAB AROUND THE COLUMN, WHICH HAVE GREATER THICKNESS THAN THE REST OF THE SLAB.

FLAT SLAB IS DESING BY TWO METHODS
1. DIRECT DESING METHOD.
2. EQUIVALENT FRAME METHOD
