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

Create a 3 dimensional model of the residential building with a rendered view

AIM:

To create a 3 dimensional model of the residential building with a rendered view using AutoCAD software and explain the procedure step by step to obtain the result.

INTRODUCTION:

AutoCAD is a computer aided design software and drafting software application.

In this project, i have used important commands and settings like,

* 3D Basics and 3D Modelling setup

* Line, 3Polyline, Polysolid - to create objects, walls.

* Layers - to assign objects and differentiate the drawing.

* Region, Boundary - to create regions.

* Extrude - to extend the object created.

* Subtract - to subtract objects.

* SWEEP - to create the hand railing.

* Material Browser - to assign different materials to objects.

* RR (Rendering) - To render the 3D drawing.

* Camera - to insert camera and view from cam angle.

* Lights - Distant lights were used in this project.

* Block - to create window blocks.

* Hide - to hide the extra wireframes and visualize a 3D model.

* UCS - To change the plane and work easily.

* various view types like Hidden, Shade, Isometric etc.. are used.

In the next step, the procedure is explained perfectly.

PROCEDURE:

• Open the AutoCAD software, start from scratch.
• Choose Imperial system.
• Select 3D MODELLING space from the settings and start drawing.
• Set the units to Engineering and Limits to 0,0 to 1000',1000'.
• Using the commands line, polyline and DText - I have created a 1st Floor and 2nd Floor Model plan for a residential building of Plot size 49'x26' with North east facing Entrance.

• Using Layers command - I have created separate layers for varying objects and assigned different colors to each layers for better understanding.

• Using Move command - Place the 2nd floor plan at a vertical distance of 11' above the 1st floor plan.

• I have created the floor slabs and made them into a region.
• Then, Using EXTRUDE command - Extended all floor slabs to a thickness of 8".

• Using POLYSOLID command - Input Height = 11', Width = 9", I have created the walls for the entire building.
• Also, using SUBTRACT command, I have created the window spacing, door spacing, Space for Glass gazing and spaces for the Balconies in the walls.

• Using the commands rectangle, polyline - I have created the window structure of 5'x4'.

• Then using MATERIAL PROPERTIES, I have assigned TEAK AND PINE wood and SOLID glass material here.

• Similarly, I have created the MAIN DOOR frame and assigned materials using MATERIAL PROPERTIES.

• Using the commands 3P, EXTRUDE - I have created the stairs with riser 8" and Tread 1'.

• After creating the stairs, I have placed it in the building.

• Using the commands Line, 3P - I have created a glass frame first.
• Converted the frame to a region using REGION command.
• Then i have created Individual blocks separately and Made each blocks into a region.
• Now, EXTRUDE the whole frame and blocks to a thickness of 2".
• Now using SUBTRACT command, subtract all the blocks from the frame to create an empty space and get the actual frame like shown below.
• Now, using Rectancle command create rectangles of the size of empty blocks and convert them into regions.

• Now, using MATERIAL PROPERTIES, I have assigned ALUMINIUM METAL to the frame and BLUE GLAZING GLASS to rectangle blocks.

• This is the MATERIAL PROPERTIES window, where I have used different materials throughout the diagram.

• 2nd Floor BALCONY DOOR.
• Using the commands 3P, REGION, EXTRUDE, SUBTRACT - I have created the Glazing Glass door structure for the 2nd floor balcony.

• Then, using move command, I have placed the Glass door structure in the building.

• Using MATERIAL PROPERTIES, I have assigned ALUMINIUM METAL to the frame and BLUE GLAZING GLASS to the rectangle blocks.

• Similarly, Using the commands 3P, REGION, EXTRUDE, SUBTRACT - I have created the Glazing Glass window structure for the 2nd floor Lounge area.

• Again, Using MATERIAL PROPERTIES, I have assigned ALUMINIUM METAL to the frame and BLUE GLAZING GLASS to the rectangle blocks.

• Using the commands 3P, REGION, EXTRUDE - I have created the 2nd Floor Balcony HAND RAIL of height 4' with 2" thickness.

• Another View angle of the balcony hand rail shown below.

• Using MATERIAL PROPERTIES - I have assigned SOLID TRANSLUCENT GLASS to the structure as shown below.

• Different view angles of the balcony are shown below.

• Similarly, SOLID TRANSLUCENT GLASS material is aslo used at other places as shown below.

• Using the command POYLSOLID, I have the created the sunshade for the window.

• Again, POLYSOLID command, I have created the Parapet wall as shown below with input height of 4' and width of 9".

• Front SHADED view of the completed drawing.

• FRONT Hidden view of the completed drawing.

• FLAT WITH EDGES view of the drawing.

• View of CAM1.

• View of CAM2.

• View with Cameras on.

• Isometric 3D view of the Building.

• Isometric Shaded view of the building.

• I have placed distant lights and put them on.
• Using RR command, I have initiated the rendering process.
• Rendered view of the building.

• Here, I have selected the region for rendering.

• Here, I have set the Environmental Exposure ON and selected COOL LIGHTS.
• And, Using RR command, I have initiated the rendering process.
• Rendered view of the building with Environmental Exposure on.

• Different view angle of the rendered image.
