Creating 3D Isometric view of various structural elements in AutoCAD

Aim - To create 3d Isometric view of building with plan and elevation

Procedure -

• Drawing the plan in top view,with line command draw aline of 10'9" vertically and horizontally such that a L shape wall is formed.and give offset of 9" from two sides
• Draw the window using offset command give the offset of 4'2" from corner of wall and again give offset of 3'2" from the line for window same as similarly on the other side also,offset 4'3" from the cornar,3' for the window

• use command 3do for 3d orbit the view so that 3d view is seen.now create a region in the wall are by command "BO" for boundary.go to shaded view to see the boundary
• Now extrude the region,giving a height of 10'.command EXTRUDE give height 10'
• Draw a rectangle over window portion and extrude it to 3' i.e to sill level.Similarly create a rectangle at top.extrude it downwards to a height of 3' from top
• Create layer for wall and place it in wall layer .In the top view using polyline create an outline of plan and then place it in bottom by move command @0,0,-10'
• Craete a region by boundary .extrude it downward to a height of 4". Similarly create a polyline at top and extrude it to height of 6".Make it union and place in wall layer

• Elevation at A-A - Draw the elevation 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 and then offset 3" for the frame and 4" for mullion
• Also offset 4' downward for plinth and 6' upward for roof slab from 10'.Create different layers for frame,mullion and glass

• place the 2d drawing in alignment to 3d.group the elvation by group comand,so that all will be in single selection
• By 3d rotate the image making it parallel to 3d wall.select the axis then give angle as 90 degree
• Creating frame ,mullion and glass of window and using boundary command create a region
• Explode it and delete all other except window.if region is created fully,substract,select larger region then smaller one.Extrude the region,giving 3" value
• Similarly create region for mullions by "BO" boundary command and 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 the window created in 3d model.Make sure that mullion are inside the frame and glass is inside the mullions
• Isometric view of elevation A aand creating elevation B

• go to top view and extend the lines from the plan.Draw 4" offset at bottom and 6" at top
• draw a window at a heiht of 3" from the bottom and offset 7' from bottom to get the top of window.Give the thickness by offsetting the rectangle by 3" for frame and 4" for mullion
• Similarly create levation B-B window same as we created in elevation A-A

Aim - Creating 3d view of building facade

Procedure -

• Creating the plan with rectangle command create a rectangle of 10'9" and 6'9". offset 9" for wall thickness. create window of 3' width

• Extrude the height as the sill kevel 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 is 2'5" +4'+4'6" = 10'11' create a region in part of wall for extrusion by command "BO" with extrude command extrude the created region giving a height of 10'11"
• Creating window using rectangle command at the bottom of window position.Extrude it to a height of 4'6" and similarly create a rectangle at the top and extrude 2'5" downward with union command,make all the wall in union
• Draw a recatngle of 4'x3' in top view.window detailing is done ,2" offset for frame and 3" for mullion,then 12" for glass area
• craete region in frame of window by "BO" command,making frame as layer. Extrude 3" for thickness of frame
• For mullion cfeate another region in different layer and extrude 1.2".and for glass create a region and extrude 0.6"
• Move this object and place window on gap in the 3d wall
• Creating floor go to top view and create a rectangle extrude it by 5"
• Group the created model and copy this model for 1st floor on top.and same for other floor

• Creating top frame- Type "UCS" command and place the ucs on top face of building.Draw a rectangle with dimension 9"x4".extrude it by 6'5".copy it on other side
• Again,create rectangle on top face.extrude it by 4" and create a roof on top by rectangle and extruding it

Aim - To create 3d view of Stairs

Procedure -

• Creating steps - With tread as 1' and rise as 6" ,draw the step in top view 2d wireframe.Landing is 3' and the waist slab is 6" thickness.join all these to form the section of stairs
• Extruding the stairs - 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 stair.with 3d rotate select x axis and give 90 degree angle
• Creating balustrades and handrails - place the UCS on the tread and create a circle of diameter 2".Extrude at a height 3'2".copy it in all treads and also in landing
• For handrails create a polyline joining the balustrade by 3dpolyline.create a circle of radius 2" and sweep it by selecting the circle and then polyline

Aim - To draw 3d view of wall with spread footing

Procedure -

• Creating the plan with line command draw a vertical line of 7500mm and 230mm width
• draw a centre line in wall and offset 150mm on both sides so that the total width is 300mm
• From the 300mm line offset 25mm on bothe sides then the total width become 350mm
• from the centre again offset 300mm on both sides.the total width is 600mm
• Extend the horizontal line.offset 3300mm from both sides for door opening of 900mm
• Create door in opening by circle and line.hatch the wall,foundation with different pattern.ANS 132 for wall,solid for footing.AR-CONC for bottom PCC

• Making the 2d plan to 3d - Footing RCC with 3do make a suitable view.make layer for footing RCC,footing steps,wall and door
• Craete a rectangle - profile on top of plan of footing RCC.place in respective layer and copy it.create a region by boundary command.extrude it y 300mm
• Creating footing steps - Go tot op view and create profile for footing step in 2d plan and copy it and place in 3d paln with the help of snap tool
• Create region by "BO" command.extrude it by 400mm,again create a profile and place such that the midpoint of 2d profile coincides with 3d object.create a region and extrude it by 400mm
• Now create a profile for foundation in different layers and place it in top of 3d model.extrude it to height of 550mm
• Creating floor - Create a rectangle for floor and extrude it to height of 50mm

• Creating wall - Now create profile for wall on both sides of door.copy it and place in 3d model and extrude at a height of 3300mm
• Creating lintel beam - Create a rectangle profile at top.move it by move command @0,0,-1050.extrude it at height of 150mm
• Creating top portion of wall - Create recatngle at top face.Extrude at height of -1050mm.
• with union command,make the extrude part as part of wall

• Creating shade - Keep the UCS on side face.draw a horizontal line from bottom of lintel,then a vertical line 50mm to top
• On the other side draw a vertical line of 100mm upward.then join these two points of 50 and 100.and group it.create region by boundary command by palcing the ucs on side face of jamb of door.Extrude it towards side till the opening.
• Create top slab - Create a rectangluar profile on top of wall and extrude it by 150mm
• Creating parapet and coping - Creating parapet of width 150mm and height 750mm. craete a recatngle of 7500mm and 150mm on top of 3d model.extrude it by 750mm
• For coping in sdie face view place,the ucs and draw 40mm width line from parapet with projection of 60mm.create a region by "BO" command
• draw a line on top use sweep option ,select the projection and then line
• Rendered view - Go to visualise tab select material browser
• for foundatin - Select a stone for wall
• For floor ,select from flooring ,select each object and give assign to selection and keep shadowson.create a cylinder and give distant light.then click on Render
