CADDS 5 Interactive Surfacing Option

Comprehensive capabilities for generating both styling and production surfaces

CADDS 5 Interactive Surfacing combines and enhances the existing CADDS NURBS with a new, dynamic, interactive surface design tool within the parametric 3D modeling software environment, embedding the resulting surfaces in the model history. This new powerful surfacing capability allows engineers to quickly and freely design complex surfaces using powerful interactive analysis features to validate the result. Existing or imported surfaces can easily and quickly be modified using this exciting new CADDS 5 package.

This package includes:

Gaussian Curvature Analysis of Aero Engine Cowling.

CADDS 5 Interactive Surface Design

Interactive Surface Design (ISD) provides a unique design environment to interactively create and modify sculptured and free form curves and surfaces. It combines the powerful capabilities of NURBS based surfacing, an interactive object/action user model, topologically related curves and surfaces and a persistent database.

Best in Class Surfacing Solution

With NURBS geometry, users can model complex sculptured shapes faster, more accurately, and with fewer surfaces. For example, NURBS geometry makes it possible to treat the hood of an automobile or the wing of an airplane as a single surface. Other surface types, such as Bezier or standard B-spline, often require many surfaces to define the same geometry.

ISD's user model simplifies the way users interact with NURBS curves and surfaces. This is achieved by providing the users with immediate access to entities for modification, dynamic modification capabilities, and immediate graphics feedback. This allows analysis information for the curves and surfaces to be displayed concurrently while the user is creating or modifying them.

Another benefit of ISD is the relational database which establishes and maintains relations between data sets, curves, surfaces and other ISD objects. This is achieved by providing persistent associations between ISD objects through the history mechanism of the parametric modeling environment. The CADDS 5 parametric part history serves as the permanent storage medium for ISD geometry, information and relations. This utilization of history functionality is transparent and provides access to ISD objects at any step in the design process. Therefore, a model may be constructed with both ISD modeling operations and parametric geometry commands. The model will be regenerated when either a parameter of parametric geometry is changed or an ISD object is modified.

The accuracy and flexibility of Interactive Surface Design software provides an ideal solution for the design of a wide range of unique surfaces, including automobile bodies, aircraft fuselages, ship hulls, and consumer products.

CADDS 5 NURBS Surface Design

NURBS Surface Design is the world's leading implementation of Non Uniform Rational B-Spline (NURBS) technology for interactive sculptured and free-form surface modeling.

The accuracy and flexibility of NURBS Surface Design software in CADDS 5 provides an ideal solution for the design of a wide range of unique surfaces, including automobile bodies, aircraft fuselages, ship hulls, and consumer products.

With NURBS geometry, users can model complex sculptured shapes faster, more accurately, and with fewer surfaces. For example, NURBS geometry makes it possible to treat the hood of an automobile or the wing of an airplane as a single surface. Other surface types, such as Bezier or standard B- spline, often require many surfaces to define the same geometry.

NURBS Surface Design software offers many features, including powerful curve and surface smoothing algorithms, surface editing, and graphical surface and curve analysis. NURBS geometry is integrated with CADDS 5 analysis, detailing, and numerical control applications. NURBS surfaces can be incorporated into parametric and explicit solid models to meet challenging surface requirements. It is also upwardly compatible with the Bezier geometry of Advanced Surface Design.

CADDS 5 IMAGEDESIGN II

Imagedesign II generates realistic, shaded color images of a complete model. Based on the surfaces and solids in the CADDS 5 database, Imagedesign II creates realistic images that enable users to clearly visualize models during every phase of the design process and from any vantage point.

Users can apply extensive color, surface, and lighting effects definitions that combine to produce sophisticated images of the model. The user can also save the image for reference or for downstream activities.

CADDS 5 CADDShade II

All CADDS 5 foundation products include a basic shading capability enabling views to be rendered as shaded or hidden line as a 'snapshot'. The rendered view may be manipulated dynamically using the mouse or 3D navigation devices.

CADDShade II provides extensive interactive shading and hidden line removal capabilities that may be applied to CADDS surface, solid and AEC models, such as routed systems and structural items during the modelling process. The rendering takes place in the graphics window and different rendering states can be applied to different views of the active drawing. Rendering states may be maintained or turned off during dynamic manipulation of views. If turned off, the dynamic manipulation occurs in wire frame mode, but returns rendered once dynamic motion is complete.

CADDShade II allows you to interactively generate, manipulate, and edit colour-shaded and hidden-line-removed images on the workstation screen and view from any angle. The software enables users to visually interpret a model's three-dimensional qualities and thus detect interferences, surface errors, mismatches, and missing or overlapping objects.
