Creating 3D Isometric view of various structural elements in AutoCAD

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

Aim :- Create a 3D Isometric View of the building with plan and elevation as shown in the Figure in AutoCAD.

Introduction :- Create a 3D Isometric View of the building with plan and elevation as shown in the Figure in AutoCAD.

Procedure :-

• Draw top view plan
• With line command draw line of 10'9" verticallay and horizontally in such a way that it form L-shape wall
• Offset of 9" is given to the two lines
• Give an offset of 4'2" from the corner of the wall
• Again give an offset of 3'2" from the line for the window
• Draw window
• Similarly, on the other wall side give an offset of 4'3" from the corner of the window
• Use command DO for orbiting the view so that 3D view is seen
• Now, create a region in the wall area by BO command for the boundary
• Now, extrude the region and give a height of ' using extrude command
• Now, create opening for windows and draw a rectangle over the window portion and extrude it to sill level
• Similarly, create a rectangle at the top and extrude it downwards to the height of ' from the top
• Union the wall using union command
• Similarly, crate the wall on the other side
• crate layer for walls nd place it layer
• In the top view by polyline , craete outerline of the plan
• Then place it in bottom by move command
• Create the region by boundary and extrude it downwards to the height of 4"
• Now, again create the elevation in 2d and draw ELEVATION-A from plan in top view
• Project the wall lines from plan and also window lines
• Give the height as 10' and then offset lines 3' from bottom and top to create window
• Then offset 3" for the frame and 4" for the mullion
• Also offset 4' downwards for plinth and 6' upwards for the roof slab
• Craete different layers for frame, mullion and glass
• Plac ethe 2D drawing in alignment to 3D
• Group the elevation by group command so that all will be in selected together at once
• By using 3d rotate commmand rotate the image making it parallel to the 3D wall
• Place second elevation in 3rd object by snapping the corner and move it to the side parallel to the 3D wall face
• craeting fromae, mullion and glass of window by boundary commmand and the create a region fo rthe frame
• extrude the region by giving -3" value
• Similarly,
• crate the region for mullions by BO command and extrude it by 0.6"
• Move the 3D wndow to the opening of window to crate 3D model
• Similarly, crate the elevation B by going to the top view and extending the lines from the plan and rest process is same.

Result :-

Top View

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

Aim :- Create the 3D View of the Building Façade as given in the plan and elevation. Also, see the detail of the window details in AutoCAD.

Introduction :- Create the 3D View of the Building Façade as given in the plan and elevation. Also, see the detail of the window details in AutoCAD .

Procedure :-

• Create the plan with rec of 10'9" and 6'9" and fofset of 9" for the wall thickness is given and create the window of 3' width
• With extrude command create the region by giving height of 10'11"
• Create window by creating the rectangle at the bottom of winndwo position
• Extrude it to a height of 4'6" and similarly create a rectangle at the top and extrude 2'5" downwards
• With union command make all walls in union
• Crtae the elevation of plan in 2D top view
• As window is in the side of plan, side elevation is taken by projecting from the lines from the plan
• Window detainling is done
• Offset of 2" for the frame is given and 3" for mullions then 12" will be the glass area
• Create the window in 3D
• Group the elevation and place the elevation in front of the 3D image
• With 3D rotate commnad rotate the elevation to 270 degrees
• Place in parallel to face and move aside
• Ungroup and delete the walls and keep only windows
• Create a region in the frame by window by 'BO' command and making frame as layer
• Extrude 3" for thickness of frame
• For mullions, create another region in different layer and extrude -1.2"
• For glass region creation excrude -0.6
• Move the object and place the window in gap in 3D wall
• Now, create the floor and go to top view and create a extrude it by 5"
• Now create the second floor and group the cretaed model and copy the created first floor on top
• Copy the floors one above the others
• Again, create the top frame and type UCS command and place ucs on the top of building
• Draw rectangle of 9'X4' and extrude it by 6'5"
• Copy it on the other side
• Again create the rectangle on the top face and extrude it by -4"
• Create the roof on the top by rectangle and extrude it

Result :-

Ans 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 :- 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 in AutoCAD.

Introduction :- 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 in AutoCAD.

Procedure :-

• Create the thread (T) and riser (R) as 6' and draw the steps in the top view 2D wireframe
• Landing is 3' and waist slab is of 6" thickness
• Join all the section of stairs
• Create a region by boundary command
• With 3d orbit place the section in such a way that it is visible
• Extrude 3' towrds the side as3' is taken as width of stairs
• With 3d rotate select X-axis and give value 90 degrees
• Now create the balusters and handrails by placing the UCS on the thread and cretae cricle of 2" dia and height as 3'2"
• Copy it in all th threds and also in the landing
• For handrails cretae a polyline joining the balustreades by 3D polyline
• Cretae a circle of radius 2" and seep it by selcting the circle and then the polyline

Result :-
