    Study Notes

    Parametric Modeling

    • Parametric modeling is a method where changing a dimension alters the model's shape automatically.
    • Feature-based modeling uses components (features) such as holes, grooves, fillets, etc., as the basic units in parametric solid models.
    • Parametric models use solid and surface modeling tools to manipulate the system attributes, which automatically adjust when input parameters change.

    Constructive Solid Geometry (CSG)

    • CSG defines a model by combining basic (primitive) shapes (cylinder, cone, prism, rectangle, sphere) using Boolean operations.

    Boundary Representation (BR)

    • BR defines a solid model by its surfaces.
    • BR uses points, edges, etc., to define the object's boundaries.
    • Many finite element method (FEM) programs use BR because it easily controls volume meshing.

    Parametric Modeling Advantages

    • Produces flexible designs
    • Offers a range of ways to view 3D models
    • Enhances product visualization with minimal details
    • Integrates well with downstream applications, reducing design cycle times.
    • Easy reuse of existing design data, and
    • Improves design efficiency.

    • Siemens NX is an advanced CAD/CAM/CAE software from Siemens.
    • An integrated solution for design, simulation, and manufacturing.
    • Enables companies to realize the value of the digital twin.

    Creo Parametric (Pro-Engineer)

    • Creo Parametric is a 3D CAD parametric modeling software.
    • Owned by PTC.

    • Context Toolbars: Appear based on selections in the graphic area or Feature Manager Design Tree, offering context-specific actions.
    • Command Manager: Organizes tools into panels for specific actions. (e.g. sketches, drawings).
    • Feature Manager Design Tree: Shows components/parts and their features, hierarchical structure for assembly designs.
    • Property Manager: Displays the properties of entities or features, allowing direct property modification.
    • Confirmation Corner: Allows accepting changes to a sketch, or discarding it.
    • Status Bar: Provides concise information related to current actions (e.g. sketch status, measurements).
    • Graphics Area: Displays the model and allows interaction (e.g. manipulating items, selecting objects).
    • Heads-up View Toolbar: A toolbar with features for managing views. (e.g. Zooming, panning).
