Creating 3D Isometric view of various structural elements in AutoCAD

1. Create a 3D Isometric View of the building with plan and elevation given.

Aim : To create a 3D isometric view of the given building with plan and elevation.

Procedure :

Step 1 :

• First we have to open the autocad and the set the maximum limit and minimum limit on the screen.
• Here first have to draw the rectangle using the rectangle command.
• Next we have to draw the two windows of sizes of 3' x 9" and 9" x 3'-2".

Step 2 :

• Now we draw the elevation of A and the elevation of B.
• We draw the given elevations using the line command and we put the dimensions using the dimlinear command.

Step 3 :

• First we draw the window of the size 3' x 4'.
• We draw the this window using the line command and extruded using the extrude command.

Step 4 :

• Next we draw the window of the size 3'-2" x 4'.
• We draw the this window using the line command and extruded using the extrude command.

Step 5 :

• Next we draw the walls using the extrude command.
• Next we use the layers for providing the colours to them.
• Next we attach the created windows to the walls.

Step 5 :

• Next we draw the walls using the extrude command.
• Next we use the layers for providing the colours to them.
• Next we attach the created windows to the walls.

Step 6 :

• Next we use the 3dorbit command to see the different views of the given figure.

2. Create the 3D View of the Building Façade as given in the plan and elevation. Also, see the detail of the window

Aim : To Create the 3D View of the Building Facade as given in the plan and elevation and need to create the window using the given dimensions.

Procedure :

Step 1 :

• First we have to open the autocad and the set the maximum limit and minimum limit on the screen.
• Here first have to draw the rectangle using the rectangle command.
• Next we have to draw the window of size of 3'-2" x 9".

Step 2 :

• Next we use the region command and select the objects, then press enter.
• Then after total objects will become the one region.
• Next we need to extrude the plan using the extrude command, with the height of 40'-10".
• Next we need to substract the four window portion vertically in a building facade with the distance 5'-11" with the window size of 3' x 4'.

Step 3 :

• Next we use the union command and press enter.
• Then after select the total drawing and press enter.
• Next the window portion will be clearly visible in the building facade.

Step 4 :

• Next we select the custom visual style as shaded with edges

Step 5 :

• Next provide the layers for the building facade of skyblue colour

Step 6 :

• Next we close the top surface of the building facade using the extrude command

Step 7 :

• Next we draw the window of the size 3'-2" x 4'.
• We draw the this window using the line command and extruded using the extrude command.

Step 8 :

• Now put the building facade in the 3d isometric view using the 3dorbit command

3. Create the ismoteric 3d view of a stair with railing as shown in the plan and elevation. Assume the size of the balustrades and the hand rails.

Aim : To create the ismoteric 3d view of a stair with railing as shown in the plan and elevation.

Procedure :

Step 1 :

• First we open the autocad and set the maximum limit and minimum limit.
• Next we set the units as architectural and take the precison as 0'-0".
• Next we draw the stairs using the line command.
• We draw the stairs with the riser of 6" and tread of 1'.

Step 2 :

• Next we use the 3drotate to rotate the figure from the step:-1.
• Next we use the extrude command to extrude the rotated figure to form the stair in 3D View.

Step 3 :

• Next we draw the railing using the circle command and sweep command.
• Next we show the stairs in the side view using the 3drotate command .

Step 4 :

• Now put the stair in the 3d isometric view using the 3dorbit command

4. Create the 3D view of a Wall with spread footing . Create the Door opening only. Assume the size of the parpaet and the coping. See the plans and elevation for the details. Also, create a rendered view of the model with materials as of your choice.

Aim : To create the 3D view of a Wall with spread footing And need to create a rendered view of the model with materials.

Procedure :

Step 1 :

• First we open the autocad and set the maximum limit and minimum limit.
• Next we set the units as decimal and take the precision as 0.
• Next we have to draw plan of wall with spread footing with given dimensions as shown in the below figure.

Step 2 :

• Next we draw the 3d isometric view of the wall with spread footing using the extrude command.

Step 3 :

• Next provide the layers for the wall with spread footing with different colours for different parts.

Step 4 :

• Next we provide the different materials for the wall with spread footing

Step 5 :

• We select the camera and put it in the required postion and then press enter.
• Next click on the camera then the small tab will appears at the top of the left corner.

Step 6 :

• Finally we select the render option and then slowly it changes to the rendering view
