  • Overview The Wireframe and Surface workbench allows you to create wireframe construction elements during preliminary design and enrich existing 3D mechanical part design with wireframe and basic surface features. As a complement to Part Design, this product meets the requirements of solids-based hybrid modeling.

    The features-based approach offers a productive and intuitive design environment to capture and re-use design methodologies and specifications.

    As a scalable product, Wireframe and Surface can be used in cooperation with companion products such as Part Design, Assembly Design and Generative Drafting. The widest application portfolio in the industry is also accessible through interoperability with CATIA Solutions Version 4 to enable support of the full product development process from initial concept to product in operation.

    The Wireframe and Surface User's Guide has been designed to show you how to create and edit wireframe and surface features as well as hybrid parts. There are often several ways to reach the final result. This guide aims at illustrating these various possibilities.

  • Using This Guide This guide is intended for the user who needs to become quickly familiar with the Wireframe and Surface product. The user should be familiar with basic Version 5 concepts such as document windows, standard and view toolbars.

    To get the most out of this guide, we suggest you start reading and performing the step-by-step tutorial Getting Started. This tutorial will show you how to create a basic part.

    The next sections deal with the creation and modification of various types of wireframe and surface geometry you will need to construct parts.

    You may also want to take a look at the section describing the Wireframe and Surface workbench menus and toolbars.

  • What's New? Open Bodies have changed names: they are now called Geometrical Sets. Their behavior is exactly the same as the open bodies'.

    New Functionalities

    Managing Ordered Geometrical Sets Optimal CATIA PLM Usability for Wireframe and Surface

    Enhanced Functionalities

    Creating Lines You can now automatically reselect the second point while in repeat mode

    Creating Circles You can now trim the tangency elements when creating a bi-tangent radius, a bi-tangent point or a tritangent circle

    Creating Corners An implicit plane is created even when the selected curves are not coplanar

    Creating Intersections You can now extrapolate linear elements

    Creating Blended Surfaces You can now set a variable tension

    Healing Geometry The deviation value and location is now displayed in the 3D geometry

    Editing Parameters New parameters have been added to the Helix

    Extrapolating Surfaces You can now extrapolate using the Point continuity propagation type You can now assemble the result in Curvature continuity type

    Defining an Axis System Local axis associativity for directions

    Working with a Support New options: Selectable Grid and Furtive Grid You can now create an infinite axis on the fly

    Selecting Using Multi-Output Deactivation of a multi-output is now possible

  • Getting Started Before getting into the detailed instructions for using CATIA Version 5 Wireframe and Surface, the following tutorial aims at giving you a feel about what you can do with the product. It provides a step-by-step scenario showing you how to use key functionalities.

    The main tasks described in this section are:

    Entering the Workbench Creating Wireframe Geometry

    Creating First Loft Creating Swept Surfaces

    Creating Second Multi-Sections Surface Joining the Surfaces Closing the Surfaces

    This tutorial should take about ten minutes to complete.

    The final part will look like this:

  • Entering the Workbench

    This first task shows you how to enter the Wireframe and Surface workbench and open a design part.

    Before starting this scenario, you should be familiar with the basic commands common to all workbenches. These are described in the Infrastructure User's Guide.

    1. Select Mechanical Design -> Wireframe and Surface Design from the Start menu.

    The Wireframe and Surface workbench is displayed.

    9Page Wireframe and Surface Version 5 Release 13

  • 2. Select File -> Open then select the GettingStartedWireframeAndSurface.CATPart document.

    The following design part is displayed.

    In the rest of this scenario, you will add to the existing elements of this part to complete the design.

  • Creating Wireframe Construction Elements

    This task shows you how create wireframe construction elements using the vertices of solids.

    1. Click the Line icon .

    The Line Definition dialog box appears.

    2. Create a line by selecting a vertex on Pad 1 and the

    corresponding vertex on Pad 2.

    11Page Wireframe and Surface Version 5 Release 13

  • 3. Repeat this steps to create four lines as shown in

    the opposite figure.

    12Page Wireframe and Surface Version 5 Release 13

  • Creating a First Multi-section Surface

    This task shows how to create a multi-section surface.

    1. Click the Multi-

    section surface icon

    .

    The Multi-section Surface Definition dialog box appears.

    2. Select the curved

    edge on each pad as

    sections for the multi-

    section surface.

    Arrows must point

    the same way on

    each side of the multi-

    section surface.
