    Study Notes

    Parametric Modeling

    • Parametric modeling is a method where modifying a dimension changes the entire model's shape automatically.
    • Feature-based modeling breaks down the model into components (features) like holes, grooves, etc.

    Constructive Solid Geometry (CSG)

    • CSG creates models by combining basic shapes (primitives) like cylinders, cones, and spheres using Boolean operations (union, intersection, subtraction).

    Boundary Representation (BR)

    • BR defines a solid model by its boundaries (surfaces).
    • Used in Finite Element Method (FEM) as it allows easy internal meshing.

    Parametric Modeling Software

    • SOLIDWORKS: A parametric modeling software by Dassault Systèmes, popular in mechanical, automotive, and electrical engineering.
      • Combines CAD, CAM, and CAE functionalities.
      • Allows estimating cost and manufacturability.
    • CATIA: By Dassault Systèmes, widely used in automotive and aerospace for product design, parametric modeling, and PLM (Product Lifecycle Management).
      • Combines shape sculpting with parametric associativity.
      • Useful for virtual human models for simulations.
    • Siemens NX (Unigraphics): A high-end CAD/CAM/CAE software from Siemens Digital Industries Software for integrated design, simulation, and manufacturing solutions.
    • Creo Parametric (Pro-Engineer): Parametric modeling software by PTC, for engineering, manufacturing, and industrial services.
      • Uses parametric and freestyle surfacing features.
    • Fusion 360: Autodesk's cloud-based 3D modeling software integrating CAD, CAM, and PCB features for product design and manufacturing.
      • Supports parametric and non-parametric modeling.
    • Autodesk Inventor: Parametric modeling software; mainly for mechanical designs; user-friendly interface; suitable for direct, free-form designs.

    SOLIDWORKS User Interface

    • Menu Bar: Contains menus, quick access tools.
    • Toolbars: Contain tools for specific design tasks (click Tools > Customize).
    • Context Toolbars: Appear when interacting with elements in the graphics area, providing relevant actions.
    • Flyout Tool Buttons: Group related commands, like creating various rectangle types.
    • Command Manager: Manages part and assembly designs, properties, and configurations.
    • Feature Manager Design Tree: Hierarchical structure displaying components, parts, and features in an assembly or drawing.
    • Property Manager: Used to specify properties for elements.
    • Configuration Manager: Allows creating, selecting, and viewing multiple configurations of parts and assemblies.
    • DimXpert Manager: For managing tolerances in designs.
    • Search: For finding information and commands.
    • Graphics Area: Main area to view, manipulate, and create models.
    • Reference Triad: Helps orient models.
    • Origin: (0,0,0) coordinate of the model or active sketch.
    • Heads-up View Toolbar: Enables common view manipulation tools including zoom, rotate, and pan.
    • Task Pane: Accesses resources, libraries, and reusable design elements.
    • Confirmation Corner: Displays OK/Cancel to accept or discard changes.
    • Status Bar: Provides information about actions and the system.

    SOLIDWORKS Sketching

    • Sketching is the basis for creating 3D models.
    • Can be created on default drawing planes (Front, Top, Right) or created planes/faces.
    • Two modes: click-drag and click-click for sketching entities.
