CATIA is 3D CAD software used for design in industries like aerospace, automotive, and shipbuilding. It was created in 1977 by Dassault Aviation. The software allows users to create sketches, parts, assemblies, and drawings. Key features include the specification tree, sketcher, part design, assembly design, and wireframe and surface design tools. Users can create 2D sketches and profiles to extrude or revolve into 3D parts, then assemble parts while applying constraints to define their relationships in the final product model.

2. • 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.

3. The 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.

4. • Sketcher
• Part Design
• WireFrame and Surface Design
• Sheet Metal Design
• Assembly
• Drafting

6. • 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

9. 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

11. 1. Create a new CATProduct using File -> New ->
Product.
2. Use the Product Structure tools to lay out the
main assembly structure
3. Use Insert Existing Component or Insert New Part
to create geometry in the Assembly
1. Use Constraints to capture the design relationships
between the various parts in the assembly
