Catia is a 3D CAD software used for design in industries like aerospace, automotive, and shipbuilding. It was started in 1977 by aircraft manufacturer Dassault. The presentation covered the main modules of Catia including Sketcher, Part Design, Wireframe and Surface Design, Sheet Metal Design, and Assembly Design. It discussed the specification tree, different toolbars, and how to create and modify parts and assemblies. Examples were provided such as creating a plummer block to demonstrate Catia capabilities. In summary, the presentation provided an overview of Catia software, its history and applications, key modules, tools, and examples of part and assembly design in Catia.

3. Introduction
• Catia is also known as computer
aided three dimensional
interactive application. CATIA
was started in 1977 by French
aircraft Manufacturer AVIONS
MARCEL DASSAULT
SYSTEM.
• It is also used in aerospace
,automotive, shipbuilding, and
other industries 2

4. Specification Tree
Provides access to the history
of how a part was constructed,
and shows the product
structure.
• Parts can be modified by
selecting them from the spec.
tree.

8. Part Design
•The part design application is used to create solid
models of parts
•Solid parts are usually created from 2D profiles that
are extruded or revolved to form a base feature.
• Parts can be modified by selecting their features in
the specification tree.

11. Assembly Design
• The Assembly Design application allows you to create a
product model from a number of separate parts
• The parts in a product assembly are not joined together,
but assembled as they would be in a physical assembly
• The product assembly structure is hierarchical and allows
you to model complex product relationships
• Constraints can be applied between the parts in assembly
to define relationships between them
