3D ISOMETRIC VIEW OF BUILDING ,BUILDING FACADE, STAIR AND SPREAD FOOTING
AIM : To draw the 3d isometric view of:
1. Building given plan and elevation
2. Facade of a building
3. Stair
4. Spread footing
COMMANDS USED:
1. Extrude - To give height to a surface or giving distance or hright in z axis of an object in x y plane so that i becomes 3d.
2. Offset - To draw the offset line. Command "O"
3. UCS - Command "UCS" . To change the UCS so as to draw in that face ie, x and y plane will be made in the selected face so that it is easy to draw in that plane. Default is UCS world.
4. Box- To create a box . It is found in the ome toolbar.
5. Union- Command :UNION" . To make diffrent 3d object ointo a single enitity.
6. Subtract - Command "SUBTRACT" . To subtract one 3d object from another . First select the object from where to be subtracted then the object which needs to be subtracted.
7. Move - Command "M" . To move an object in a particular axis . Coordinates also can be given for moving an object after the command.
8. 3d orbit- Coomand "3DO" . To rotate the object so that we can view around 360 degree.
9. Boundary - Command "BO" . From this command also region can be created . If the encircled region is created by different lines , boundary is used. select region in the dialogue box and click on the internal point where region is to created and then extrusion is done.
10. Sweep - to make 3d of an object in a given path. In toolbar select sweep , seelct the object to be swept then the path.
11. Render - Command "RR" - to see the view of the object after materials are applied.
1. 3d isometric view of a building
Aim : To create 3d isometric view of a building with plan and elevation.
Procedure:
Step:1 Drawing the plan
In the top view,
* With line command ,draw a lne of 10'9" vertically and horizontally such that a L- shape wall s formed.
* Offset 9" line from the two lines.
* Give offset of 4'2" from the corner of the wall
* Again give offset of 3'2" from that line for the window.
Step :2 Draw the window
* Similary on the other side also, offset 4'3" from the corner ,3' for the window.
Step:3 Making it 3d
* Commadn"3do" fro 3d orbit and orbit the view so that 3d is seen
* Now create a region in the wall area by command "BO" for boundary.
* Go to shaded view to see the boundary
* Now extrude the region , givng a height of 10'. Command "EXTRUDE" , give height =10'.
Step :4 Creating opening for windows:
* Draw a rectangle over the window portion.
* Extrude it to 3' ie to sill level.
* Similarly create a rectangle at the top
* Extrude it downwards to a height of 3' from the top.
* Union the walls by command "union" - select all the walls
* Similarly create the window on the other side wall.
* Create layer for walls and place it in wall layer.
* In the top view, by polyline create an outline of the plan
* Then place it in the bottom by move command "M" @0,0,-10'.
* Create a region by boundary.
* Extrude it downwards to a height of 4".
* Similarly create a polyline at top and extrude it to a height of 6".
* Make it a union and place in wall layer
Step: 5 Creating elevation in 2D
Elevation at A-A
* Draw the elavation A from the plan in top view.
* Project the wall line from the plan and also the window lines
* Give the height as 10' ,then offset lines of 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 from the 10'.
* Create different layers for frame, mullion and glass.
Step:6 Creating 3d of elevation
* Place the 2d drawing in alignment to the 3d
* Group the elavation by group command , so that all will be in a single selection
* By 3d rotate rotate the image making it parallel to the 3d wall. seelct the axis then give angle as 90 degree.
* Place the 2d elevation in the 3d object by snapping the corner and then move it to the side parallel to the 3d wall face
Step:7 Creating frame, mullion and galss of window
* By "bo" command craete a region fro the frame.
* Explode it and delete all other except window.
* If region is created fully, subtract , select larger region then smaller one.
* Extrude the region, giving -3" value.
* Similarly create region for mullions by "BO"- boundary command.
* Extrude it by -1.2".
* Create a region for glass by creating rectangle boundary if boundary is not there.
* Extrude it by 0.6".
* Move the 3d window to the opening of te window craeted in 3d model.
* Make sure that the mullions is inside the frame and glass is inside the mullions ( after a distance from the frame mullions are provided likewise glass)
Isometric view of elevation A
Step:8 Creating elevation B
* Go to top view and extend the lines from the plan .
* Draw 4" offset at ottom and 6" at top
* Draw window at a height of 3" from the bottom and offseting 7' from bottom to get the top of the window.
* Give the thickness by offsetting the rectangle by 3" for frame and 4" for mullions.
Step : 9 Creating 3d of elevation at B
* Place the 2d elevation parallel to the 3d elavation in top view
* In 3d view, Rotate the 2d elavation such that the 2d elavation is in parallel to the 3d face.
* For that rotate 3d command , select y axis then give the angle as 9 degree.
* Place the 2d on the face of 3d , then move the 2d image paralle to the face.
* Delete the wall and keep only the window for extruding.
Step:10 Creating frame, mullion and galss of window on elevation B
* By "bo" command craete a region fro the frame.
* If region is not created , create a reactnagle through the outline and give region
* If region is created fully, subtract , select larger region then smaller one.
* Similarly create region for mullion and the glass with respective layers.
* Extrude the frame -3" mullion by -1.2" and glass by -0.6".
* Place it in the 3d wall
Isometric view of elevation B
* Extrude the handle also.

2. 3d view of a building facade
Aim :Creating 3d view of builidng facade
Procedure:
Step:1 Creating the plan
* With rectangle command create a rectangle of 10'9" and 6'9".
* Offset 9" for the wall thickness.
* Create window of 3' width.
Step:2 Extruding the height
* As the sill level height is given as 4'6" and window height as 4' ,and top height from the window is 2'5".
Total height of one floor =2'5"+4'+4'6" =10'11"
* Create a region in the part of wall for extrusion by command "BO".
* With extrude command extrude the created region giving a height of 10'-11".
Step:3 Creating windows
* Create a rectangle at the bottom of the window position.
* Extrude it to a height of 4'6".
* Similarly create a rectangle at the top and extrude 2'-5" downwards.
* With union command , make all the walls in union.
Step:4 Creating windows
* Create the elevation of the plan in 2D. -top view.
* As the window is in side of plan ,side elevation is taken by projecting lines from the plan
* Window detailing is done , 2" offset for frame and 3" for mullions, then 12" will be the glass area.
Step: 5 Creating window in 3D
* Group the elavation.
* Place the elvation in front of the 3D image.
* With 3drotate rotate the elavation by 270 degree.
* Place it in parallel to the face and move it to side .
* Ungroup and delete the walls and keep only the window.
* Create region in the frame of window by "BO" command , making frame as a layer.
* Extrude -3" for the thickness of frame.
* For mullions create another region in different layer and extrude -1.2".
* For galss also create a region and extrude-0.6".
* Move this object and place the window on the gap in 3d wall.
Step:6 Creating floor
* Go to top view and create a rectangle
* Extrude it by 5"
Step :7 Creating 2nd floor
* Group the created model and copy the created 1st floor on top .
* Copy the 4 floors as such
Step : Creating top frame
* Type "UCS" as command and place the ucs on the top face of building
* Draw a rectangle with dimensions 9" x 4".
* Extrude it by 6'5".
* Copy it on the other side .
* Again create rectangle on top face .
* Extrude it by -4".
* Create a roof on top by rectangle and extruding it .

3. Creating isometric 3D view of stairs
Aim : To create 3D view of stairs
Procedure:
Step: 1 Creating steps
* With tread as 1' and riser as 6" , draw the steps in the top view 2d wireframe.
* Landing is 3' and the waist slab is 6" thickness .
* Join all these to form the section of the stair.
Step:2 Extruding the stair
* Create a region by boundary command.
* With 3d orbit place the section in such a way that it is visible.
* Extrude 3' towards the side as 3' is taken as width of the stair.
* With 3d rotate -select x axis and give the value 90 degree.
Step:3 Creating balustrades and handrails
* Place the UCS on the tread and ceate a circle of diameter 2" and height 3'2".
* Copy it in all the treads and also in landing.
* For handrails, create a polyline joining the balustrades by "3dpoly". 3d polyline
* Create a circle of rdius 2" and sweep it by selecting the circle and then the polyline.
