CATIA, a computer-aided three-dimensional interactive application developed by Dassault Systemes in 1977, is widely utilized in aerospace, automotive, and shipbuilding industries. It features various modules including sketcher, part design, assembly design, and wireframe & surface design, allowing users to create solid models, manage components, and define product relationships through constraints. The document provides details on toolbars, features, and steps for creating assemblies within CATIA.

2. Introduction of CATIA
• 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. CATIA Modules
• Sketcher
• Part Design
• WireFrame and Surface Design
• Sheet Metal Design
• Assembly
• Drafting

5. SKETCHER

2. Operations Toolbar
3.Constraint toolbar

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

7. Toolbars in Part Design
1. Sketch-Based Features 2. Dress-Up Features
 Pocket
 Shaft
 Rib
 Multi-section solid

8. 3. Transformation Features
 Translation
 Rotation
 Mirror
 Pattern

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

10. Assembly Design
• Constraints Toolbar
 Coincidence
 Contact
 Offset
 Angular
• Product Structure Tools
Insert New Component
Insert New Product
Insert New Part
Insert Existing Component
Replace Component

11. Steps for Creating an
Assembly
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
4. Use Constraints to capture the design relationships
between the various parts in the assembly

12. Wireframe and Surface
• Wireframe Toolbar
 Create Point
 Create Line
 Create Plane
 Create Projections
• Surface Toolbar
 Extrude Surfaces
 Surface of Revolution
 Offset Surface
 Sweep Surface
 Create Filling Surface
