Procedure:

Open AutoCAD

In Startup settings start from scratch select Imperial (Feet and Inches)

Open grid and snap settings.

Change snap and grid spacing.

Type ‘un’ in command box and press enter.

Change units’ type to decimal and precision to 1’1/16” and insertion scale to inches.

Change the workspace setting of AutoCAD from ‘drafting and annotation’ to ‘3D Modeling’.

Open Layer properties and create new layers by clicking on new layer or right click on any layer and select new layer to create new layer.

Change the current layer to 3DWall

Create a rectangle of dimensions 10’9”X10’9” at any point on the screen
Offset the rectangle to inside to distance of 9” as wall thickness
Delete the left and bottom lines and extend them to the edges

Change the current layer to 3D_Window_Frame

Draw the window with dimensions 3'2" at top and 3' on right side as shown in figure.

Change the view to 3d by clicking on home button of view cube

Set UCS as world

Create the boundaries for the walls using ‘BO’ command
Extrude the boundaries created to total height of 10’10”
Select all the wall and use group command to group then together

Draw rectangles at both windows and change them to boundaries using boundary command
Extrude both rectangles drawn to height of 3’4” as shown in the figure
Draw rectangles at top of both window openings and change them to boundaries using boundary command

Type UCS and click on face and select the face having 3’ wide window

Draw a rectangle from bottom part of window with dimensions @3’,4’

Type UCS and click on face and select the face having 3’2” wide window

Draw a rectangle from bottom part of window with dimensions @3’2”,4’

Change the ucs back to world

Extrude the rectangle drawn at top side to top edge of window

Change the current layer to 3D_Window_Frame

Type UCS and click on face and select the face having 3’ wide window

Draw a rectangle of dimension @3’,4’
Offset the rectangle to inside to distnce of 3”
Offset the offset rectangle to inside to distnce of 4”

Start the boundary command and click on pick points

Click inside the window frame area and press enter

Start SUBTRACT comman

window elevation A,

window elevation B,

Change the workspace setting of AutoCAD from ‘drafting and annotation’ to ‘3D Modeling’

Open Layer properties and create new layers by clicking on new layer or right click on any layer and select new layer to create new layer

Create a rectangle of dimensions 6’9”X10’9” at any point on the screen
Offset the rectangle to inside to distance of 9” as wall thickness
Explode the rectangles drawn
Delete the top line and extend them to the edges

Change the current layer 3D_Window_Frame

Create the window opening of dimensions 3’ wide as shown in figure
Add dimensions are drawn using dimension layer
Create the boundaries for the walls using ‘BO’ command
Extrude the boundaries created to total height of 10’10”
Create a boundry region over the window lines
Extrude the boundary to aheight of 4’6”
Draw a rectangle on top of the window opening using rectangle command
Chanhe the rectangle into a region
Extrude the region to distance of 1’3” to below and then window openin is created as shown in figure

WINDOW DETAIL:

Draw a rectangle of dimension @3’,4’
Offset the rectangle to inside to distnce of 2”
Offset the offset rectangle to inside to distnce of 3”
Draw center line connecting midpoints
Offset the lines to both sides to a distance of 3”
Trim all the unnecessary edges

Group all the items to create the elevation view
Copy the block having 4’ height window and place it 3 times as shown in figure

Create the top part of the drawing using 4” wall with height 6’5” from top

Create a boundary for the wall
Extrude the boundary to 9” .
