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

AIM OF THE PROJECT- Creating a 3D rendered model for a Residential Building in AutoCad.

INTRODUCTION- COMMANDS USED FOR DRAWING THE 3D RENDERED VIEW OF BUILDING ARE AS FOLLOWS.

-         Extrude- Location: Draw > Modeling > Extrude

This AutoCAD 3D Extrude command allows the user to create a 3D object by extruding a 2D face along a line or path.

-         Sweep- Location: Draw > Modeling > Sweep

This command helps the user to extrude the 2D objects without the 2D face being orthogonal to the beginning of the path.

-         Union- Location: Modify > Solids Editing > Union

This AutoCAD 3D command allows the user to combine two objects converting into one single object.

-         Subtract- Location: Modify > Solids Editing > Subtract

This command is opposite to the union command; this command works when there is a common area in both the objects. Then this command subtracts the object A from the object B.

-         Intersect-  Location: Modify > Solid Editing > Intersect

With this AutoCAD 3D command the user is left with the area that is common to both the objects.

-         Revolve- Location: Draw > Modeling > Revolve

This AutoCAD 3D command creates a 3D solid by revolving a 2D object around an axis.

STEPS FOR CREATING A PLAN-

• Open Auto Cad.
• In the right left corner click on the settings icon that is the icon of workspace.
• Select 3d modelling.
• Enter UN (Units ) command in the command box and change the type as decimal and select precision as 0.0
• Now enter Dim style in command box and modify the settings and select primary units as decimal and give precision as 0.0
• Select line command and draw in top or 2D mode.
• Line command is used to draw the plan.
• Command X line and draw line in X Direction as well as in Y direction.
• Trim the unwanted corner lines.
• Offset 230 for wall.
• Offset 5000 for bedroom in X direction and 5000 in Y direction.
• Offset 230 for wall.
• Mtext command is used to give naming to the plan.

STEPS FOR CREATING THE 3D PLAN.

• In the right left corner click on the settings icon that is the icon of workspace.
• Select 3d modelling.
• Command boundary and in that select region.
• Create boundaries as well as regions of the plan.
• Extrude the regions that are the walls to the height of 3000 from bottom.
• Floor to floor height of the building is 3000.
• Create different type of layers using layer properties like 3D walls, window frames, slab, window glass etc as desired.
• Assign colors to each layer separately
• Line command is used to draw the windows and doors.
• Extrude the windows and doors to the suitable depth.
• Rotated 3D is used to rotate the objects as in windows and doors.
• Move and copy command is used to move the windows to their desired locations.
• Command polyline at the terrace and create the parapet wall at the top of the building.
• Command polyline and create the plinth of the building of 600 at the bottom.
• Create the staircase and extrude it to the distance of 1200.
• Create the mumty separately and place it on the top of the building.

STEP for Designing and placing of 3D doors, swinging louver,sliding window, normal window and glass grill.

The 3D doors, swinging louver,sliding window, normal window and glass grill was designed using the tools polyline, sweep, extrude, union, 3D rotate, subtract command etc.   

Applying materials:

On the visualize tab click on material library and apply suitable materials for 3D doors, swinging louver,sliding window, normal window and glass grill as shown.

We can apply materials by just dragging the materials from the library to the object which is to be materialized.

STEPS FOR RENDERING-

• Go to the visualize tab from the fibbon.
• This will give access to the panels like light, sunlight, Camera, Animations, Render and Views.
• Create different views using the camera anf render the building.
• Place the lights at the desired locations.

All of the materials was copied upto the number of times it was required, using th 3D rotate command it was rotated to the required direction and then they all are placed at their respective positions at shown.
