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 Draw the 3D Isometric view of the building as shown in figure

Introduction:

• A plan view of wall two elevation of windows on both sides are given and they are to be converted into a 3D model

• The height of floor is given as 10' and height of window from the floor is 3'

• The basic render workflow is to attach materials to the 3D objects of a model, place user defined lights

• Add a background and start the render with the render command.

Procedure:

• Initially open the AUTOCAD and go to 3D modeling

• Then set the units as engineering and imperial (inches)

• Open gird and snap setting

• Set the spacing and major lines

• We have to take a rectangle using the command of size 10'9"

• Next was to draw the window of size 3' x 9"

• Next, we use the region command and select objects, then press enter

• we get total object will come as one region

• Type UCS and click on face and select the face having 3' wide window

• Draw a rectangle from bottom part of window with dimensions @3'-4'

• Draw a rectangle from bottom part of window with dimension as @3'2"-4'

• Next, we use the region command and select the object and press enter

• Group them all the objects

• Enter boundary command and click on pick points

• Click inside the window frame area and press enter

• Next use SUBTRACT command

• Select the Bigger region then select smaller region to subtract

• Change the current layer to 3D window

• Click inside the window to create Milon area and press enter

• Again, use Subtract command

• Select the bigger region and select the smaller glass region

• Change the current layer to 3D view

• Click inside the window glass area and press enter to set the boundary

• All dimension is in feet and inches

• Text and dimensions with respective layers

• Finally, the result as shown in the figure.

Result:

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

Aim:

• To draw the 3D building Facade as given in the plan and elevation

Introduction:

• A plan view of wall and two elevation views, one is of window details and second is of floor level elevation.

• One window opening on front side is given with details regarding the frame dimensions

• The height of floor is given as 9'11"

• Four building with similar dimensions is created in 3D view

• Height of the window from the floor level of each floor is given as 4'6"

• Commands are used as
• Line
• Rectangle
• UCS
• Dim linear
• Extrude
• Region
• Boundary
• 3D face
• 3D orbit
• Realistic
• Copy
• Move
• Union
• Plan

Procedure:

• Open AUTOCAD select new one

• Set the limits and DIMS

• Type UN in command and press enter

• Set the unit as Engineering and precision as inches

• Change the workspace set as 3D modeling

• Open layer properties and create new layer to all the layers

• Layers are shown in the figure

• Create the rectangle as 6'9" x 10'9" at any point

• Offset 9" the rectangle inside as wall thickness

• Explode the rectangles drawn

• Delete the top and bottom lines and extend that.

• Create the window opening of dimension 3' wide

• Mention the dimensions as respectively

• Set the UCS world

• Set the view style control as Shaded

• Command BO for create walls

• Extrude the walls height was 10'9"

• Select all the wall and use group them

• Delete the window lines

• Create a boundary region over the window lines

• Extrude the boundary to a height was 4'6"

• Draw a rectangle on top of the window opening using rectangle command

• Change the rectangle into a region

• Extrude the region to distance of 1'3"

• Change the layer to 3D window frame

• Enter UCS and click on face and select face 3' wide window

• Draw a rectangle of dimension @3'4"

• Offset the rectangle to inside distance of2"

• And again offset 3" inside the rectangle

• Trim all the unwanted lines

• Command BO and select the frames for region

• Command Subtract Select the bigger region then smaller region to sub

• Command BO Click on pick point

• Click inside the Mailon area and press enter

• And subtract them

• Command BO create the region

• Click inside the window glass area and press enter

• Group all the objects

• Copy the block having 4' height window and place it 3 time

• Create the top part of the drawing using 4" wall with height 6'5" top angle

• Create a boundary wall

• Extrude the wall 9"

• Finally, the 3D modeling as shown in figure

• The result consists of different views such as Front, Top, SW, NE isometric views

Result:

3. Create the isometrics 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 the plan and elevation.

Introduction:

• An isometric drawing is a 3D representation of an object, room, building, stairs or design on a 2D surface

• This is due to the fact that the fore shortening of the axes is equal

• In an isometric drawing the object appears as if it is being viewed from above from one corner, with the axes being set out from this corner point.

Procedure:

• Open the AUTOCAD click the new one

• Then set the limits and DIMS

• Type UN command set as engineering Precision as 0

• Command rectangle to create a first step of stairs

• And offset Side edges 1"

• Offset for Thread as 1' multiple 9 times and landing 3'

• Then use dim linear and texts respectively

• Change the view front to create the side elevation of stairs

• Take line command riser as6" and thread is 1'

• Copy up to midland

• Now the portion is change to region

• And EXTRUDE it distance of 4"

• Create the handrails Using a command of Circle and Polyline

• And sweep the objects 2"

• Now mention the dimensions

• We have to develop the isometric view of this staircase

• For this we have to hide the text and dimensions

• Then change the view to Sw

• Finally, the result as shown below in the figure

Result:

4. Create the 3D view of a Wall with spread footing. Create the Door opening only. Assume the size of the parapet 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

Introduction:

• An isometric drawing is a 3D representation of an object, room, building, stairs or design on a 2D surface

• One of the defining characteristics of an isometric drawing, compared to other types of 3D representation, is that the final image is not distorted.

• In an isometric drawing the object appears as if it is being viewed from above from one corner, with the axes being set out from this corner point.

Procedure:

• Open the AUTOCAD click the new one

• Then set the limits and DIMS

• Type UN command set as engineering Precision as 0

• draw the plan of wall with spread footing with given dimension as shown in the figure

• Create the layers as shown in the figure

• Next, we draw the 3D isometric view of the wall with spread footing

• Using the command Extrude

• Next provide the layers for the wall with spread footing with defend colors for different parts as shown in the figure

Result:

• The 3D view of a wall with spread footing and created a rendered view of the model with material successfully in the AUTOCAD
