Project 2_Creating a 3D rendered model for a Residential Building in AutoCad
Aim of the project :- To draw the 3D residential building and to create the rendered view Introduction :- The general commands used for drawing the building is as follows : Line Polygon Rectangle Circle Erase Copy Trim Offset Extend Move Rotate Dimension Text Fillet Extrude 3D Rotate Etc
The drawing in the project is done with help of AUTOCAD 3d software.
Procedure:
External and Internal wall – 230mm thick
For Staircase : - Treads : 250 mm, Rise : 165mm
W – 1200 X 1500
V – 700 X 500
D1 – 1000 X 2000
D2 – 900 X 2000
All the dimensions are in mm
Procedure :-
Click on AutoCAD application and open this application
Type QNEW in command bar and enter
Select default setting as Metric
In default setting click on use a wizard and in that advance setting and set unit as decimal and precision as 0 and press Next
Set Angle as Decimal Degree and precision as 0 and click next
Set Angle Measure as EAST and press NEXT
Set Angle Direction as Counter-Clockwise and press NEXT
Set Area by providing Length as 50m and Width as 50m
Press finish
Keep ortho, Object snap >ON
Keep Snap and Grid > Off
Un+enter
Type > Decimal, Precision > 0
Units to scale inserted content > milimeter
Enter
Steps to draw the Plan
Take the line command
Specify first point > click anywhere on the sheet
Specify next point > type 10050 > Enter by keeping curser rightside
Specify next point > type 11230 > Enter by keeping curser upside
Specify next point > type 10050 > Enter by keeping curser Lefttside
Specify next point > type 11230 > Enter by keeping curser downside
Enter
Take the offset command
Specify distance > 230
Select object > Right side vertical line
Specify distance > 2460
Select object > Right side vertical line
Specify distance > 2690
Select object > Right side vertical line
Specify distance > 230
Select object > Top side Horizontal line
Specify distance > 4000
Select object > Top side Horizontal line
Specify distance > 4230
Select object > Top side Horizontal line
The stair case hall is ready
Take offset command
Specify offset distance > 900 to show landing width
Select object > Top horizontal
Specify Offset distance > 250 to show the tread
Select object > Landing line
Continuously provide the offsets for tread as per design requirement
By using line command divide the staircase tread in two parts to show the different flights
The ground floor plan is ready
PROCEDURE FOR 3D MODELLING
Step 1: The units of the drawing sheet is set to Engineering precision.
Step 2: Construction line in horizontal and vertical direction are drawn using the command ‘XL- h’ and ‘XL-v’
Step 3: A corner is created by trimming the bottom and left side of the construction line using the trim command: ‘TRIM’
Step 4: after drawings are created, page is set to 3d modelling, home tab is clicked.
Step 5: with the help of extrude command various extrusions are created.
Step 6: Then rendering is done as per the requirement.
Step 7: Similarly offset lines are created based on the room size and dimensions mentioned in the plan.
Step 8: drawings are saved in various viewports.
Results Obtained:
The drawing presented in this project contain 3d models of given plans and section. The dimensions of the rooms are mentioned with different layer options. screenshots and files are attached for your reference.
