Creating 3D Isometric view of various structural elements in AutoCAD

Ans1.

Aim:

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

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:

Then type BO command to create the boundary region for the walls and then extrude it.

Now, again go to top and assign layer to the walls.
Then create the boundary region so thaat it can be extruded to create the 3D wall.
Draw a rectangle at the window portion and create the boundary to it and then copy this rectangle vertically at adistance of 3'4" , 4' and 3'10".
Then extrude this rectangle to complete the wall.
Then provide the necessary hatching for the windows and the isometric view is completed.
Now, the final isometric view is as given below:

Aim:

To create the 3D view of the building facade as given in the plan and elevation:

Choose the line command and create the plan as gien in the question.
Now, provide the hatch using the hatch command.
Now using dimlinear command provide the dimensions and using the mtext command provide the texts.
Create the boundary region using the boundary command.
Then extrude it upwards at a height of 40'10".

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.
Create the window separately in the right view.
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.

RESULT:

Aim:

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

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'.
Then extrude it at a distance of 4'.
The balustrade is created using circle of radius 2" which is then extruded upwads at a height of 3'.
Similarly handrail is also created with radius 2".

Result:

Aim:

To create the3D view of a wall with spread footing, also create the rendered view of the model with materials of choice.

Procedure:

Now, create the boundary region using the command BO.
Then, extrude the created region to a extrusion height of 7500mm.
Now, go to visualise tab of the ribbon and choose the material browser and then assign materials to each element.
Create the door opening, render this figure.
The rendered image obtained is:
