What is Catia?

Catia is a potential 3D software for professionals. On the contrary to 3D applications, Catia software is based on the modeling technique utilizing curves instead of a mesh approach. It is the most accurate modeling method. Since 3D files are used as a guide for the machine tools in the industry, CATIA is the most popular and regularly used software application.

Delve deeper into the functionalities of Catia, a leading 3D software for professionals, by practicing extensively and seeking clarification on any queries you may have during Catia Training sessions conducted by our experienced trainers.

Catia Versions

The requirements of several enterprises evaluate how software is built. Every CAD professional seeks to create new and enhanced. CATIA has continuously improved its versions since 1980 to meet design requirements. 

Catia V3 and V4

The primary version of CATIA was released in or around 1982. The Boeing Company utilized the primary 3D CAD tool, the CATIA V3. Building 3D designs requires the utilization of CATIA V3; CATIA V3 is converted from the Mainframe systems to UNIX. In 1994, Dassault Systems created CATIA V4 and released it. 

The native formats like STEP, DXL, STP, and IGES have been included in CATIA V4. .model, session, .exp, .dlv3, and .dlv4 are the file extensos of CATIA V4. CATIA V4 contains a function that converts CATIA V4 files to V5.

CATIA V5

The most extensively used and popular version of CATIA is V5. For both non-parametric and parametric modeling, V5 is the CAD program. By including new features like enhanced usability and extended compatibility, CATIA V4 replaced it. Without SIMULIA and DELMIA packages, CATIA V5 can do fundamental FEA Analysis and machining.

CATIA V6

The 3D collaboration solution of CATIA V6 is also called CATIA 3D experience. Users can define and implement the driving system for managing difficulties and producing goods on schedule. It also enables us to assemble and model complicated products. 

Engineers can utilize it to do digital prototyping, like analysis and simulation of design, function quality design, and performance across the design process. A real-world experience that predicts performance in the real world is possible through CATIA V6 integration of challenging product behavior into the product description.

With the adaptable and accessible user interface, this workbench allows you to build 3D mechanical components at any stage, from sample sketches to thorough iterative designs. Following are the few Workbench commands:

1) Pad: It is used for converting drawings into 3D designs. Pad is also called Extrude.

2) Face: It is used for modifying the angle of the selected faces to get the required form for that particular face.

3) Fillet: It can build a smooth edge using the required size.

4) Pocket: For making a hole-in-pad design at a particular distance, utilize the pocket command.

Sectors that use CATIA

The style and design of a product have a significant impact on how it performs in the market. The main components of CATIA Design/Styling are creating innovative materials and shapes, achieving good software quality, and obtaining the best decision-making tools. 

CATIA Graphical User Interface

Specification Tree

  • The specification tree will be displayed on the left side of the screen while we are working with CATIA.
  • It tells us how a part is constructed and displays the product structure.
  • We can select the product entities from the specification tree or geometry tree.
  • We can modify the parts by choosing them from the specification tree
  • Press “+” for opening the tree branch
  • We store the solid parts in the PartBody branch of the Part tree

Sketcher Module

Sketcher Workbench is a group of tools that allows you to create and restrict the 2D geometries. After that, Features can be made for Solids, or changes can be made to solids through these 2D profiles. We can utilize the sketcher workbench in various ways. We can access the sketcher workbench by using the top pull-down menu or by choosing the sketcher icon. After entering into Sketcher, we have to select a plane to sketch on. For exiting from the Sketcher, choose the "Exit Workbench" icon.

Sketcher workbench includes the below standard workbench toolbars:

Workbench-specific toolbars

  • Operation toolbar: After creating the profile, we can modify it through commands like mirror, trim, chamfer, and other commands available in toolbar.
  • Profile toolbar: The commands available in this toolbar will enable you to create simple and more complex geometrics.
  • Sketch toolbar: The commands present in this toolbar will allow you to work in different modes, which makes sketching simpler.
  • Constraint toolbar: We can constrain the profiles through geometrical or dimensional constraints through the commands of the Constraint toolbar.

Part Design Module

The part design environment module is used to create the 3D models from the 2D sketches built in the sketcher environment.

Feature and Commands of Part Design Module

SHAFT Command

It is the same as the revolve command in other CAD softwares. The Shaft command is highly used for building shaft-like parts. It needs the axis alongside which the sketch can be revolved.

RIB Command

Generally, this command is called SWEEP; however, in Catia, it is called the RIB command. It includes material along the guide curve. RIB is utilized for making components like pipes, springs, etc.

Slot command

The slot command removes the material along the guide curve.

Assembly module

The assembly environment is used for mating two or more part models to or from the complete assembly. Assembly module has two approaches: Top-down approach and Bottom-up approach. 

We can create the complete design structure in the product environment in a top-down approach while the bottom-up parts are made separately.

Drafting Module

Drafting is the mechanism of creating the 2D machine drawing for the 3D part models for sending to manufacturers.

We have two kinds of CATIA Drafting:

1) Interactive Drafting and 

2)Generative Drafting.

Geometric Modeling

Computer Aided Engineering(CAE) field contains Computer Aided Manufacturing(CAM) and Computer Aided Design(CAD). Computer Aided Drafting, Finite Element Analysis, and Computer Geometry Modeling are the remaining subcategories of CAD.

Mathematical representation of an object's geometry through the software is called computer geometric modeling. The represented item form is explained in the geometric model. Curves are used in computer geometric modeling to create geometric shapes and handle the object's surface and analytical functions. For making the geometric model of the object, we can use the following three stages:

  • Create geometric objects using circles, points, and lines commands in the CAD software.
  • We can use commands to change the geometric parts like scaling, rotation, etc.
  • Incorporate the components of the objects for creating the final geometric model.

Geometric Solid Modeling

The object's edges, surfaces, and nodes can be defined through solid modeling. It depicts the filled and included mathematically in an extensive and precise manner. Contrary to surface modelers, Solid modelers start with concrete or use topological principles to ensure that all the surfaces are correctly joined.

Comprising of constructive boundary representation and solid geometry, solid models are depicted through the two techniques. Basic solid objects are integrated into the constructive solid geometry. Removing or adding the forms generates the final solid shape. In boundary depiction, borders are used to define them. It delivers the orders that rotate or sweep the defined face into the third dimension for producing solid and defining the points.
