Type Z enter to zoom and A enter to all.

Now in settings selecting 3D Modelling and visual style control  to 2D wireframe.

A default layer for both dimension, windows,text and lines was choosen with a colour .

Using the line command the Plan, Elevation A and Elevation B was drawn.

The walls and windows was placed in two respective layers.

Using the DIMLIM command the dimensioning was completed.

Using the single line text all the required texts was also made. 

A copy of plan layout is taken to draw the 3D image.

All the layers exept the wall and window layer was turned off.

The south west ismetric view is made the default view.

Dialogue box will open

Click on > Pick a point

Click on the internal portion of wall and press
Enter

Click on the extrude option from from the home tab.

Select object > Click on the walls
Specify extrude height > 10'10" and press
Enter

Change the visual style control > Shaded
It will shows the following result

The next task is to project the windows for that:

Type REC and draw a rectangle on top of the window.

Click on the extrude option from from the home tab.

Select object > Click on the rectangle
Specify extrude height > 3' and press
Enter.

Use the Extrude, Substract and union command to finish and place the window.

In the similar way the other window was also created.

Change the visual style control > Shaded
It will shows the following result

Creating Elevation Windows.

Change the current layer to 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 inside rectangle to inside at a distnce of 4"
Start the boundary command and click on pick points

Click inside the window frame area and press enter
Type SUBTRACT command
Select the bigger region and then select the smaller regions to subtarct them.
Follow the same procedure for all the three boxes.

In the same manner window mullion layer and window glass layer was made

Now using the MOVE command place the window at the correct position as shown.

The floor area was also made into a region and a suitable colur color was provided to it.

RESULT:

The 3D isometric view of the building is as shown.

In the same manner window mullion layer and window glass layer was made

The building is made of four floors ans each floor layout is same.

So the ground floor is copied and stacked on top of each other as shown

RESULTS:

The 3D view of building facade was created.

Type UN and press enter

Under Drawing Units, select Archetectural (feet and inches)

To draw the hand rails.

A circle of radius .75" was drawn.

A circle with same centre and of radious .4" was drawn.

.4" circle is extruded to a height of about 3'-2 and the .75" circle was extruded to a height of 2'

The cylindircal tube of larger dia circle is raised to a height of about 6".

Now a sphere of radius 1" was drawn placed at the centre of the larger dia cylinder.

Using the Union command al of them was made into a single unit ans then it was placed on steps as required.

Draw a polyline connecting all the top edges of hand rails.

Draw a circle of diameter 2" on top of the first hand rail.

Create a region of the circle drawn and do a Sweep command.

Select the circle as object to sweep.

Select the poly line drawn as path of sweep as shown in figure.

Copy the same and place them at equal intervals as required.

RESULTS:

The staircase was made and  after applying suitable materials is as shown.

Type UN and press enter

Under Drawing Units, select metric (millimeter)

Now the lower limit is set to 0, 0 and upper limit to 100, 100

Type Z enter to zoom and A enter to all.

Now in settings selecting 3D Modelling and visual style control  to 2D wireframe.

Using the line command the Plan and section was drawn.

All the respective materilas like dimenisons, walls, door etc was placed in the same layer.

Hatch commands of texture and pattern was used for hatching 

Using the DIMLIM command the dimensioning was completed.

Using the single line text all the required texts was also made
