Result:

In this project For the given condition at first the hand sketch draft file was done for the 60*20 site as depending on that the AutoCAD file was created depleting the draft drawing was drawn as shown in the figure 1 and by this plan consideration a section view and the side elevation was visualised and drawn in the AutoCAD as figure 2 and figure3 respectively and layers columns and beams was used during the drawing which will be helpful in differentiating the architectural and structural drawing which shows the position of the columns and beams by this reference a 3d model was created in the Autocad3d software With the proper us of the materials, layers and many other tools to assign the properties and usage of the solid editing was done wherever required and tools like extrude, sweep fillet were very helpful During the drafting of this model

and here are the some of the rendred images of the model
