Advantages of CADD 1 of 2

• Increase in the productivity of the designer.• Improve the quality of the design.• Better communications.• Creating documentation of the designing.• Creating the database for manufacturing.• Ability to create digital prototypes as oppose to costly physical

prototypes.• Perform simulation including motion simulation, static

simulation and finite elements analysis.

AutoDesk Inventor Professional software package

Autodesk Inventor is a software used for 3D modeling

and 2D drawing. Inventor is a powerful CADD tool used

for basic product design idea or virtual prototype with

its complete set of drawings.

Part Files

Part files are used to create single parts and sheet metal parts. Parts(components) can be combined to create complex assembly. Part files have the file extension .ipt.

Assembly Files

Assembly files are used to create assemblies and subassemblies. Parts and subassemblies used to build an assembly are known as components. Assembly files have the extension .iam

13

Presentation Files

Presentation files are used to create exploded, animated, and stylized assembly models that show how separate parts and subassemblies interact within the full assembly. Presentation files have an .ipn extension.Umm Al-Qura UniversityCollege of Engineering & Islamic ArchitectureMechanical Engineering Department
