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

Aim:

To create the 3D rendered model for a Residential Building in AutoCAD.

Introduction:

The 3D view of a wall spread footing is created in AutoCAD in 3D Modelling workspace using primarily the line and Extrude tools. The procedure of drawing is explained in detail with diagrams of each step and the final result is given.

Procedure:

• Create a circle od Diameter 60 at the corner of the first step.
• Select the Sweep tool.
• Sweep the circle along the polyline created earlier.
• Repeat the above procedure to create the other flight.

• Enter CO in the command line to select the Copy tool.
• Select the window, doors, ventilator and the stairs individually and copy them to their desired locations.
• Use 3DROTATE tool to rotate the objects as required.
