Introduction:

A plan view of wall of two elevation views of windows on both sides are given and they are to be converted into a 3D model. 2 window openings on both sides are given with details regarding the frame dimensions, mullion dimensions and handle height. The thickness of bottom floor and top roof are also given as 4” and 6” respectively. The height of floor is given as 10’. Height of window from the floor is 3’.

Procedure:

Open AutoCAD

In Startup settings start from scratch select Imperial (Feet and Inches)

Open grid and snap settings

• Change snap and grid spacing to 1’
• Change major line every grid line to 10
• Turnoff adaptive grid

Type ‘un’ in command box and press enter

Change units’ type to decimal and precision to 1’1/16” and insertion scale to inches

Change the workspace setting of AutoCAD from ‘drafting and annotation’ to ‘3D Modeling’

Step 1: Creating Layers

Open Layer properties and create new layers by clicking on new layer or right click on any layer and select new layer to create new layer

Layers are created as follows.

Step 2: Creating Layers

Change the current layer to 3D_Wall

• Create a rectangle of dimensions 10’9”X10’9” at any point on the screen
• Offset the rectangle to inside to distance of 9” as wall thickness
• Delete the left and bottom lines and extend them to the edges as shown in figure

Step 3: Creating 3D View

Change the view to 3d by clicking on home button of view cube

Set UCS as world

• Create the boundaries for the walls using ‘BO’ command
• Extrude the boundaries created to total height of 10’10”
• Select all the wall and use group command to group then together

• Draw rectangles at both windows and change them to boundaries using boundary command
• Extrude both rectangles drawn to height of 3’4” as shown in the figure
• Draw rectangles at top of both window openings and change them to boundaries using boundary command

  • Draw a rectangle from bottom part of window with dimensions @3’,4’

  Type UCS and click on face and select the face having 3’2” wide window

  • Draw a rectangle from bottom part of window with dimensions @3’2”,4’

  Change the ucs back to world

  • Extrude the rectangle drawn at top side to top edge of window
  • Group all the wall components together.

Step 4: Creating Elevation Windows

Window at Elevation A

Change the current layer to 3D_Window_Frame

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

• Draw a rectangle of dimension @3’,4’

Step 5: Creating Views

Click on home button of the view cuble and zoom for better view

Go to visuvilise tab and click on new view

• Set view name as VIEW 1
• Click on current view and press ok

Click on the NE isometric view of the view cube and zoom for better view

Go to visuvilise tab and click on new view

• Set view name as VIEW 2
• Click on current view and press ok

Click on the Top view of the view cube and zoom for better view

Go to visuvilise tab and click on new view

• Set view name as VIEW 3
• Click on current view and press ok

Result:

Initially all the layers necessary are created with respective line types and line weights. Then plan view is drawn as shown in step 2. Then from step 3 the 3D view is created with respective layers assigned. The UCS view is changed accordingly to make changes to the 3D view and 3D dimensions.Boundary command is used for creating regions along the boundaries and extruding them. After this view are created for showing result.The result consists of different views of the 3D model such as top view(View 3), SW isometric(View 1), NE isometric(View 2), Windows.

• All dimensions are in Feet and Inches
• Text and dimensions are added with respective layers

1. View 1(SW isometric)

2.View 2(NE isometric).

AIM:- To create the ismoteric 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.
• One of the defining characteristics of an isometric drawing, compared to other types of 3D representation, is that the final image is not distorted.
• This is due to the fact that the foreshortening 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.
• Isometric drawings begin with one vertical line along which two points are defined.

COMMANDS USED:-

• Line command
• Rectangle command
• UCS command
• Dimlinear command
• Region command
• Extrude command
• Substract command
• Box command
• Units command
• Dimstyle command
• 3Dface command
• 3Dorbit command
• Hide command
• Explode command
• Move command
• Copy command
• Dist command
• Solidedit command
• Union command
• Boundary command
• 3Dmirror command
• 3Drotate command
• Erase command
• Plan command
• Circle command
• Sweep command

PROCEDURE:-

Step:-1

• First we open the autocad and set the maximum limit and minimum limit.
• Next we set the units as architectural and take the precison as 0'-0".
• Next we draw the stairs using the line command.
• We draw the stairs with the riser of 6" and tread of 1' as shown in the below figure.

Step:-2

• Next we use the 3drotate to rotate the figure from the step:-1.
• Next we use the extrude command to extrude the rotated figure to form the stair in 3d view.

Step:-3

• Next we draw the railing using the circle command and sweep command.
• Next we show the stairs in the side view using the 3drotate command as shown in the below figure.

Step:-4

• Now put the stair in the 3d isometric view using the 3dorbit command as shown in the below figure.

RESULT:-

• The given 3d isometric view of the stair is drawn successfully in the autocad in detailed manner.

SW VIEW:-

NW VIEW:-
