7. Make the window opening 3' wide, as illustrated in the illustration.

8. With a dimension layer, more dimensions are drawn.
Making a 3D view

9. By clicking the home button on the view cube, the view can be changed to 3D.
Make UCS the world.

10. With the 'BO' command, define the walls' perimeters.

11. Extrude the drawn lines until they reach a height of 40'10".

12. Use the group command to select every wall and group them all together

13. delete the window lines

14. Create a boundary and expand the perimeter to 4'6"height.

15. Draw a rectangle top of the window opening using rectangle command.

16. Create a region for the rectangle.

17. Extrude the window 1'3"downward as shown in the figure.

18. Window with 4"width create a layer for the window frame to current.

19. Ucs select the face, draw a rectangle of 3'and 4', and adjust the rectangle.

20. Next change the current layer to 3D mulion and create a boundary click points.

21. click inside area and press enter, substract the bigger rect with smaller one.

22. Next change the current layer to 3D Glass and create a boundary click points.

23. click inside area and press enter, substract the bigger rect with smaller one.

24. Extrude the window projections.

25. Place the windows in elevation. and create the top part of the building as shown in the figure.

8. offset the line 25mm bottom line

9. again offset the bottom line to 100mm

10. Change the current layer to wall draw a rectangle of dimensions 230 x 3300 from the top left edges of ground level.

11. Draw a roof of thickness 150mm and parapet wall of height 600mm

12. For the footing select the layers draw the rectangle of dimension 230 x 600 below the floor level, 330 x 400 for first level, 430 x 400 for the second level and 670 x 300 as third level.

13. Trim all unwanted lines. create a door and give the shade to door.

14. create each boundary and extrude the created boundaries.

15. Go for the rendering add materials and use Cam command to take screenshot.

Result: The given 3D Isometric View of a wall with spread footing is sketched as shown below.
