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

Aim :- To draw the 3D residential building and to create the rendered view

Introduction :-

The general commands used for drawing the building is as follows :

Circle
Erase
Copy
Trim
Offset
Extend
Move
Rotate
Dimension
Text
Fillet

3D Rotate

Etc.

The dimensions:

External and Internal wall – 230mm thick
For Staircase : - Treads : 250 mm, Rise : 165mm

Set Angle as Decimal Degree and precision as 0 and click next
Set Angle Measure as EAST and press NEXT
Set Angle Direction as Counter-Clockwise and press NEXT
Set Area by providing Length as 50m and Width as 50m
Press finish
Keep ortho, Object snap >ON
