CATIA V5 Part Design Overview for Mechanical Modeling


CATIA V5 Part Design is a core workbench used to create precise, feature-based solid models for mechanical components. It follows a history-based design approach, where features are built sequentially in a specification tree. This allows associative updates across sketches, pads, pockets, and dress-up features, ensuring that any design modification automatically updates dependent geometry. Such parametric control makes CATIA Part Design highly effective for mechanical components used in geotechnical, structural, and industrial workflows, especially in training environments like Pigso Learning.


Part Design also integrates seamlessly with assemblies and downstream PLM systems, preparing models for validation, manufacturing, and ENOVIA V5 VPM data management. This makes it a foundational skill covered in every professional CATIA design course.


Core Toolbars in CATIA V5 Part Design


The Sketch-Based Features toolbar forms the foundation of solid modeling. Tools such as Pad, Pocket, Shaft, and Groove allow users to create and remove material using sketches. These features are essential for building primary shapes like plates, brackets, and shafts.


The Dress-Up Features toolbar includes Fillet, Chamfer, Draft, and Shell, which refine geometry by adding edge blends, wall thickness, and draft angles—critical for manufacturability.


Transformation features such as mirror, Pattern, and Scaling support symmetry and repetition, improving modelling efficiency and consistency.


For advanced modeling, Boolean Operations such as Assemble, Add, and Remove enable multi-body design, commonly used in complex mechanical parts.


Key Workflow Steps


A typical workflow begins by entering the Sketcher on a selected plane and creating geometry with proper constraints and dimensions (for example, a 50 × 30 mm rectangle). After exiting the sketch, a Pad feature is applied by defining limits and extrusion depth. Holes or cutouts are created using Pocket, often set to Up to Last for through-cuts. Dress-up features like Fillet (3 mm radius) and Draft (2°) are then applied to improve strength and manufacturability. Renaming features in the tree (such as Base_Pad) improves model clarity and supports parametric updates.


Best Practices and Training Path

Best practices include using positioned sketches for accurate feature placement and avoiding over-constraining sketches during early design stages. For certification-focused learning, students practice creating bosses, ribs, and stiffeners to prepare models for assembly and PLM integration.


Pigso Learning offers structured CATIA V5 training, including CATIA V5 training online, designed for beginners and working professionals. These programs form part of a complete CATIA software course, covering advanced topics, CATIA customization training, and pathways toward CATIA certification course online. Learners can also progress to CATIA V6 training through a guided CATIA training program, earning a CATIA course with certificate that supports industry-ready skills.

Understanding User Subroutines in ABAQUS: UMAT and VUMAT Explained

Image
Engineers can individualize their work in ABAQUS with subroutines called UMAT and VUMAT. These tools allow users to describe advanced behavior of materials that is not included in the basic material libraries of ABAQUS. Knowing how to apply subroutines is crucial for engineers, and now many of them prefer to acquire this knowledge with a proper online Abaqus UMAT course. What is the Meaning of UMAT and VUMAT? You can use the UMAT module in ABAQUS/Standard to design materials under static and low-speed dynamic situations. ABAQUS/Explicit makes use of VUMAT to solve very fast-paced simulations. All the programs are written in Fortran, which is the usual language for coding finite element analysis applications. During every analysis step, ABAQUS uses these routines to find out how the materials will respond according to the user’s settings. The way ABAQUS makes use of subroutines At the beginning of every increment in ABAQUS/Standard, subroutines such as UMAT are used twice. At first, we...

A Complete Guide to Multiphase Flow Simulation Using ANSYS Fluent CFD

Image
In industrial processes, multiphase flow is not only prevalent—it is necessary. From pipelines and evaporators to chemical reactors and crystallizers, multiphase systems are central to many unit processes across many industries. Among these, the oil and gas industry is one of its biggest players of these systems. The industry is not only a leading provider of global energy supply but also a principal supplier of raw materials to many chemical industries, particularly the petrochemical industry. With its far-reaching reach, every advancement in the oil and gas sector can lead to huge operational advantages and vast economic benefits. For this reason, process efficiency and accuracy are of the utmost priority. Simulation: The Key to Process Optimisation In the highly technologically developed world of today, the initial logical step toward process improvement is through simulation. Numerical simulation of a process provides a valuable tool for gaining insight into system behaviour, inves...

Structural Analysis and CDP - Concrete Damage Plasticity for Abaqus Simulia

Image
Concrete is the most prevalent construction material because of its strength and durability. But, as time goes on, concrete can start to crack, deform, and even fail at times when a certain load has been applied to it. Due to the unpredictable behaviour of concrete when stressed, engineers have the desire to have tools we can use to predict the behaviour of concrete structures and how they will respond when loads have been applied. This is where the Abaqus concrete damage plasticity model comes in. It is probably one of the best available simulation tools that can be utilized in the Abaqus suite, which will allow you to test and understand how concrete behaves under loading conditions.  In this blog, we will write about how the Abaqus concrete damage plasticity model works, how it has been applicable in a real engineering situation, and why this is a skill civil and structural engineers can benefit from having. We will also cover one of Abaqus training courses, which will enable y...
