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 the 3D isometric view of a building with plan and elevation given:
Procedure:
- Initially, open the AutoCAD and go to 3D modeling.
- Then set the units of the drawing as Engineering (feet and inches).
- Now set the limits:


- Now, in the AutoCAD take the top view and intially draw the plan as given in the question.
- Using the line command the top plan is created as below:

- Now, using the dimlin command provide the dimension.

- Now hide the dimension layer.
- Then type BO command to create the boundary region for the walls and then extrude it.
- Now, change the view to south west.
- Create the region and extrude it upwards at an extrusion height of 10'10".
- Using 3D orbit the the view direction.
- Then in the window portion of the plan create a rectangle and convert it into region and extrude it also to create a window in the wall.



- Now, go to the backview and create the window using the rec command.
- This is elevation A.
- Now provide the dimensions.


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:
Procedure:
- Initially, open the AutoCAD and go to 3D modelling.
- Then set the units of the drawing as engineering (feet and inches).
- Now set the limits:

- Now choose the line command and create the plan as gien in the question.
- Now, provide the hatch using the hatch command.
- Now using dimlin command provide the dimensions and using the mtext command provide the texts.

- Now hide the dimensions and texts and hatch to create the isometric view and elevation of the plan.





- So for that initially create the boundary region using the boundary command.
- Then extrude it upwards at a height of 40'10".
- Now create the windows at its required positions.
- Convert the figure to shaded view.
- Then draw a rectangle at the window position and convert it to a boundary region and then copy it to the window positions.
- Then extrude it to complete the 3D wall.
- Then using union command unite all the different components

- Now, create the window separately in the right view and dimension it.

- Now hide the texts and dimensions and continue.
- Then using the command rotate 3D bring that window to the front view.
- Now place these windows in the front view of the structure created.
- Now, provide the dimensions.
- Section A is also developed.
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 isometric 3d view of a stair with railing as shown in plan and elevation
Procedure:
- Initially, open the AutoCAD and go to 3D modelling.
- Then set the units of the drawing as engineering (feet and inches).
- Now set the limits:

- Initially using line command create the plan of the staircase.
- Then, provide necessary dimensions and texts.


- Now, move to front view and create the side elevation of the staircase.
- This is done using the line command.
- The riser is taken as 6" and the thread is taken as 1'.
- Now, this portion is changed to a region.
- Then extrude it at a distance of 6".

- The balustrade is created using the circle of radius 2" which is then extruded upwards at a height of 3'.
- Similarly, the handrail is also created with a radius 2".
- Now, provide the necessary texts and dimensions.

- Now, we have to develop the isometric view of this staircase.
- For this, we have to first hide the texts and dimensions.
- Then change to south west view.


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, also create the rendered view of the model with materials of choice.
Procedure:
- Initially, open the AutoCAD and go to 3D modeling.
- Then set the units of the drawing as engineering (feet and inches).
- Now set the limits:

- Now, go to the front view and create the section of the wall footing.
- Using the line command draw the given section.
- Then provide the appropriate hatchings using the hatch command.



- Provide the dimensions using dimlin command.

- Now after creating the section go to top view to create the plan.
- Then provide dimensions to complete the plan.

- Now, create the boundary region using the command BO.
- Then, extrude the created region to an extrusion height of 3000mm.


RESULT:
All the drawings are drawn using the proper commands and with the given specifications. Mainly 3Dface, ucs, hatch, sweep, rotate3d, and 3Dorbit are used in this drawing to technically specify the different components in the drawing.
