Project 2_Creating a 3D rendered model for a Residential Building in AutoCad

AIM:-

To create a 3D model of a residential building with a rendered view

INTRODUCTION :-

• 3D (3 dimensional) modeling basically refers to the process of developing the mathematical representation of any surface of an object in three dimensions using specialized software. ... The process of displaying the 3D model as a two-dimensional image is called 3D rendering.
• Introduction to AutoCAD 3D Commands. AutoCAD is three-dimensional CAD software that is used commercially across the world. Developed by Autodesk in the year 1982. AutoCAD is also available as a mobile and web app, which is marketed as AutoCAD 360.

DIMENSION :-

• EXTERNAL AND INTERNAL WALL - 9" and 4.5".
• For Draw stairs of rising 7.5" and thread of 9"
• The size of the main door is 4'5"* 7'
• The size of inside door is 2'9" * 7'
• Size of the bed room 1 = 16' x 17'
• Size of the bed room 2 = 15'x 17'
• Size of the pooja room = 5' x 14'
• Size of the toilet = 6' x 10'
• Size of the Kitchen = 7'7.5"x 14'
• Size of the hall = 21'4.5" x 25'4.5"
• Size of the dining = 16'4.5" x 11'.

PROCEDURE :

STEP : 1

• OPEN the auto cad file
• Set the new sheet and save as first
• We can draw the 2d plan first. so we want to set the units as in feet and inches with using engineering type in unit box as given below.
• I Set the limits with use of limit command as per size of 0,0 enter and 50,50 enter
• And type a zoom enter and all enter for fit the page
• Next using the line command to draw the line
• And also we can use the rectangle command for draw the plan as per size of 49' x 55'
• Uses offset command to offset the line as 9" inch.
• use the line command or L enter to draw the interior room line
• At the same offset the inner line as 9" offset for normal wall and 4.5" for partition wall
• The partition wall was placed by toilet room
• In the plan they have 3 bed rooms one open kitchen and dinning, hall.
• Draw the windows and use the block command for lock the diagram or using the join command for join the window
• And also using the same command as draw the door as per the size of given above the procedure and then lock the door or join the door.
• All the door as been placed in the every room corner as gap of 5 inches
• And draw the ventilater to attach in the bathroom.
• Use the dim command for find out the dimension and also use dimlinear for marking the dimensions.
• Draw stairs of rising 7.5" and thread of 9"
• Size of the bed room 1 = 9' x 10'
• Size of the bed room 2 = 9' x 10'
• Size of the bed room 3 = 9' x 10'
• Size of the toilet = 4' 6" x 9'
• Size of the Kitchen = 9' x 10'
• Size of the hall = 23'7" x 9'
• Size of the portico = 9'9" x 8'
• total size of building is an = 30' x 30'
• And use the text command for text the room size and dimension as for given above.
• Now we insert the stairs in the building using the move command
• We need to create a window using the standard dimensions as per Indian standards
• The size of the window is 3' * 4'. The size of all the windows in the buildings are the same
• Next, we need to create the doors using the standard dimensions as per Indian standard
• The size of the main door is 4'5" * 7'
• The size of inside door is 2'9" * 7'
• The size of all inside doors are same

STEP : 2

• First we can change the sheet into switch = 3d modelling sheet
• Select the visual style control > 2d Wireframe
• Use the 3D orbit command to set it in proper position.
• Its the tool box were used in the 3d modeling sheet

STEP : 3

• Use the layer properties
• Click the new layer
• Given the name of the layer like 3d wall
• turn the layer > on
• make a unlock
• select layer what we want to be used
• At the same above process as followed in the all layer
• and the layers as assigned in the posistion.
• Use the extrude option maken the line to wall as height of 10' feet
• Allredy the given wall thickness as given by 9" inches
• And also use the poly solid command to draw the wall
• size of plan set by 49' x 55'.
• same likes as inner wall top be finished use of extrude command
• Provide the weist slab of 100 by using line and offset command
• Take the boundry command and use the pick option to pick the slab 2d drawing.
• Pick internal point
• Select the internal portion of staircase
• Enter
• Visual style control> Shaded
• Take extrude command
• extrude command is used to maken solid up were we want to make slab thickness
• Next we turn the ground floor to another view using the 3D orbit command
• Next, we use the copy command and copy the ground floor
• Next, we use the array command and set levels up to 5 floors
• Next, we draw the parapet wall with a height of 4'
• we create the sunshade using the rectangle command, extrude command, and union command
• next click the material option in the visualize option and then press the material browser
• Select the materials which are displayed on screen

Door and windows :-

• Use the move command to set all the components in a proper manne
• Use the rectangle, extrude command to provide the architectural view
• Enter CO in the command line to select the Copy tool.
• Select the window, doors, ventilator and the
• stairs individually and copy them to their desired locations.
• Use 3DROTATE tool to rotate the objects as required.
• 3DORBIT Command is used to control the viewing of the model when copying the doors, windows, ventilators and stairs to their respective locations.
• Next, we use the copy command and copy the ground floor
• Next, we use the array command and set levels up to 5 floors
• Next, we draw the parapet wall with a height of 4'
• we create the sunshade using the rectangle command, extrude command, and union command
• next click the material option in the visualize option and then press the material browser
• Select the materials which are displayed on screen
• Next we turn the ground floor to another view using the 3D orbit command

• STEP : 4

• Go to Visualise> Render drop down list>Render Environment and Exposure.

• Turn On Environment and make other suitable adjustments as required.

• Next adjust the Date and Time under Sun Status.

• Open the Render Preset Manger dialog box.

• Select Render in> Viewport.

• Make other chages as required.

• Close the Dialog box.

• Click on the Render icon on the panel to check the camera view.

• The environment condition as making the realistic background given for the elevations

• Its taken a good look for the views
• We can select the many option make a background effect
• Here i can used the dry lake bed maken a natural green effects view.
• STEP : 5
• CAMERA VIEW :
• Take a circle command
• Place it at left bottom corner
• Extrude it at height > 5000
• Click> Visualise> camera
• Name it as » Cam1

• Set target

• Delete the cylinder

• Click on the camera it will gives the follow result

• Steps to set the Distant light :
• Take a circle command
• Place it at right bottom corner
• Extrude it at height> 20000
• Click Visualise» Create light» Distant ligh Name it as > Sun light
• Set target
• Set intensity» 100
• Delete the cylinder
• Take rr command to see the effect
• Save this image.
• STEP :6
• Use the layers to set the line and extrude and can make the reality materials to apply the object for good realistic view after rendering
• After we complete the enviroment on option
• Click on the Render icon on the panel
• We can render the image using with rendering option and taken the realistic view
• That the view can be shown in the below the results
