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

• Create 3 dimensional model of the digestive building with rendered view

Aim:

To create the 3D rendered model of the residential building in AutoCad

Introduction:

3D CAD or three dimensional computer assigned design in the technology for design and technique kal documentation which repairs manual drafting with an automatic process. Used by architect engineers and other professionals 3D cats software precisely represent and visualise objects using a collection of points in three dimension on the computer.

Most used command:

• Revolve:

Location: Draw>Modelling>Revolve

This AutoCAD 3D command create a 3D solid by removing a tubidy object around an axis

• Extrude:

Location: Draw>Modelling> Extrude

This AutoCAD 3D extrude command of the user to create 3D objects by excluding a 2D face along a line or path

• Sweep:

Location: Draw>Modelling>Sweep

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

• UNION:

Location: Draw>Solid Editing>Union

This AutoCAD command allows the user to combined two objects converting them into one single object

• Subtract:

Location: Draw>Solid Editing>Subtract

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

• Intersect:

Location: Draw>Solid Editing>Intersect

With this AutoCAD 3D command used is left with the area that is common on the both objects

Dimension:

• Plot area: 32'x45'
