Project 2_ Creating a 3D rendered model for a Residential Building in AutoCAD

********************************************************

1. 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 the different 3D commands present in the AutoCAD software. It also provides the student the experience to create a 3D model rendered from 2D sketch until the final model.

Introduction

The AutoCAD software provides different tools. The tools used in this challenge is as described below:

Line - creates line object.

Polyline - creates connected line object.

Rectangle - creates rectangle object.

Circle - create circle object.

Trim - Cut unwanted lines or shapes with the provided cutting edges.

Extend - Extend lines to opposite corners.

Move - Move objects to particular locations.

Copy - Copy objects 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 into one object. Line to polyline.

Dimlinear (DLI) - Provides vertical or horizontal linear/straight dimensions.

Dimaligned (DAL) - Provides aligned dimensions.

Dimangular (DAN) – Provides angular dimensions.

Quickdimension (QDIM) – Provides quick dimension of a geometry.

Leader - Creates an arrowhead line.

Layers - Provide identification of line or object groups by their properties.

Units - Open "Drawing Units" window to specify the drawings units.

Dimstyle - Open "Dimension Style Manager" window to modify the dimension properties.

Hatch - Provides hatching pattern in each object or internal point.

Layer - Open the layer tab which manages the line properties in a drawing.

2. Sketch and Procedure

***************

A. Create a 3-dimensional 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 rectangle 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 from 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 provision at the middle part.

• Mirror the layout of the top room and mirror it on the other side. Include the columns, walls, windows and doors to the other side.

• Add the door symbol.

• Trim and close the edges.

• Copy the door symbol to other 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 extrusion.
• 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 to 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 specified 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 door.

• Add the Slab.

• Use SolidEdit to change the solids.

• Union the available solids.

• Add Materials.

• Now Proceed to Render to Finish.

FINAL PRODUCT:

Rendered View.

3. Conclusion

***************

The AutoCAD software allows 3D sketches where solid objects or 3D surfaces are present. By using the 3D function of the AutoCAD software, one can illustrate or convert a 2D sketch into a 3D illustration.

The AutoCAD software also has visualization effects that allows the user to present the created sketches into rendered images. This gives a realistic view of the actual model which is seldom used in the Architectural and Civil Engineering Industry.
