Project 2_Creating a 3D rendered model for a Residential Building in AutoCad
Aim & Introduction Aim
This challenge aims to let the student utilize the tools in Autocad to create a 3D sketch. It aims to help the student familiarize with thedifferent 3D commands present in the AutoCAD software. This challenge aims to correlate the 2D drawing into 3D sketches
Introduction
The AutoCAD software provides different tools. used in this challenge is as described below:
Line- creates line object
Polyline- creates rectangle line object
Rectangle- creates rectangles object
Circle- create circle object
Trim-Cut unwanted lines or shapes with the provided cutting edges
Extended- Extend lines to opposite corners
Move- Move objects to particular locations
Copy- Copy obejects to particular locations
Rotate- Rotate selected objects to a particular angle with respect to base point
Array- Copy an object in a set path linearly or polarly
Join- Joins separated line objects to a particular angle with respect to base point Dimlinear(DLI)- provides vertical or horizontal linear/ straight dimensions Dimligned(DAL)- Provides dimensions with respect to the angle of the object Dimangular(DAN)- Provides angular dimensions between two line objects.
Quicklinedimension(QDIM)-provides quick dimension of a geometry Leader- creates an arrow head line
Layer- Provides identification of line or object groups by their properties
Units- Open "Drawings Units" window to specify to modify the dimension properties
Hatch- provides hatching pattern in a given object or internal point
3D orbit- allows panning in the 3D view
Extrude- Creates a 3D solid, surfaces, or 2D regions by subtraction UCS- Manages defined user corodinate systems
Union-Unions two solid or two region objects
Sketch and procedure:
Create a 3D model of the residential building with a rendered view Procedure:
-----> Decide the layers
These layers can be adjusted later as per requirement. Use the layer command

-----> Proceed with the plan drawing
Create boundary using object. Dimension 6m by 18.3m

Offset it by 250 towards the inside to project the wall. Add the plant north facing east


Now create a projected boundaries for the layout. Add lines and use the extend/trim command to sketch the plan
Start the top, position stairs in the middle

Use line and trim tool to add the wall openings and trim the unnecessary lines

Add the columns. Column size is 250x400mm


Add the doors and windows at locations where it is needed

Create the stair provosion at the middle part

Mirror the layout of the top room and mirror it on the other side. include the column walls, windows and door to the other side

Add the door sysmbol


Trim and close the edges


Copy the door sysmbol to the doors

Mirror to the other side

Turn the plan into a group


----->Create the front and side elevation of the drawing in the front view


Add the window and door locations








---> Proceed to extrusion of columns. Move elevation to the second floor

Turn off the other layers to avoid selecting them

Extrude the columns. Isolate the column layer to avoid selecting the others
Move the columns to the bottom

Extrude to the structure height




Turn on all the laures and proceed with the walls on the 2nd floor
Create regions for extrusions
Turn off unnecessary layers



Create the opening







Copy the opening edges to the other side mirror is also applicable


Create the opening for the stair



Join the 3D solids using union


Proceed with the balcony












Explode the array for extrusion

Add the line on top




Do the same on the other side


Mirror to the other side of the building

Add the slabs





Create the door and window faces





Extrude for solidity















Mirror the other side






























Once the first floor is done, copy it to duplicate the floors


Create the balcony

Separate the line for better view





Add the boundaries for extrusion



Extrude to specificified height









Create the missing windows then proceed to the first floor
Proceed with the 1st floor plan
Add the regions
Extrude and join with the solids
Add the doors
Union the available solids
Add materials
Result:
Conclusion
The AutoCAD software allows 3D sketches where solid objects or 3D surfaces are present. By using 3D function of the AutoCAD software, one can illustarte or convert a 2D sketch into a 3D illustartion
