LucidShape CAA V5 Based

LucidShape CAA V5 Based

LucidShape CAA V5 Based is an interactive tool that allows designers to perform optical simulations and analyses of automotive lighting products within the CATIA V5 environment. Because of the tool’s complete integration within CATIA V5, designers who are familiar with CATIA can easily leverage LucidShape’s powerful features to produce, with a minimal learning curve, automotive lighting products that meet performance, styling, visual branding and regulatory requirements.

Latest Features and Updates

LucidShape CAA V5 Based 2017.09 includes the following new features for optical simulations and analyses of automotive lighting products in the CATIA V5 environment:

  • LucidShape CAA V5 Based supports CATIA Version 5 R24, R25, or R26 with Service Pack 3.
  • Simulation Configurations. You can now configure simulations so that they include only the objects that are relevant for the respective simulation and analysis. You create a simulation configuration by specifying the sources, actors and sensors that will participate in a simulation; objects that are not included in the configuration are ignored and do not affect the ray trace results. This new capability makes it easy to analyze different lighting functions, such as low beams, high beams, and signal lighting functions, without having to manually reconfigure the model between simulations.
  • Simulation in Batch Mode. This release includes the ability to run all active simulations that are defined in the active model document. This enables you to schedule multiple simulations to run one after the other, without the need for intermediate input.

  • Fixed Random Seed for Simulation. You now have the option to maintain a fixed random seed for simulations, which enables you to rerun simulations while maintaining the same results. This functionality also works after saving, closing, and restoring a model, in the same session or a new session of LucidShape CAA.


  • Ray History Sensor for Candela Sensor. Enhancements to the Ray History Sensor for the Candela Sensor include the ability to restore ray paths without having to rerun the simulation after save and restore operations, the display of Ray History Sensors results as a sub-node under the simulation results in the Specification Tree for improved model organization, and the ability to use multiple Ray History Sensors in the same model.


  • Ray History Sensor for Luminance Camera Sensor. Previously, the Ray History Sensor functionality in LucidShape CAA was limited to the Candela Sensor. In this release, we introduce Ray History Sensor functionality for the Luminance Camera Sensor. This functionality enables you to restore ray paths that correspond to a specific region on a luminance camera image.


  • Light Guide Design Module. In this release, the Light Guide Designer (previously released as a beta feature) has been renamed the Light Guide Design Module and requires a separate license. The Light Guide Design Module includes the following new capabilities:
    • New shape types that provide more versatile styling opportunities. New shapes include: circle with flat, partial ellipse, square, rectangle, keyhole, and user profile.
    • Support for scaling and rotated profiles
    • Inward and outward oriented prism option
    • Enhanced exit surface construction
    • Dual optimization mode and optimization support for tapered light guides
    • Die pull direction support

Key Capabilities

Geometry Creation and Import

To build your automotive lighting model in LucidShape CAA V5 Based, you can use CATIA-generated geometry or import geometry created in LucidShape. You can then choose various sources and sensors; assign, create and edit materials and media using a materials library; and define simulation settings and analysis preferences.

  • Sources: Point, plane, cylinder, and ray file
  • Sensors: Candela, luminance camera, ray file, ray history
  • All LucidShape actor materials are supported and the material definitions are organized in a material library
  • Supports CATIA V5 workbenches so you can customize your workflows to speed up the modeling process

Easy Visual Navigation of Complex Models

Model navigation and management is highly efficient with the software’s specification tree structure, which keeps all automotive lighting components organized and accessible from a single location. For example, products have a tree section that shows and allows the editing of all LucidShape-specific elements in an entire product assembly.

Rapid Design Verification

The software can rapidly and accurately ray trace part-level models or product-level assemblies using both tessellated and NURBS simulation methods, for the most comprehensive CATIA-based optical simulations currently available. You can run a simulation on one part while you continue to work on another part in the same project.

The software also supports multi-core processing and GPU ray tracing (for tessellated mode only) to further accelerate simulations.

Full Suite of Analysis Tools

The software delivers a comprehensive spectrum of UV data analysis tools, as well as bird’s eye and driver’s views. A large set of test point standards are included to ensure that your system meets both industry regulations and company specifications. Specific analysis tools include:

  • Test tables (ECE, SAE, JIS, user defined)
  • Special views (bird’s eye view, driver’s view)
  • Variety of UV data operations (scale, shift, rotate, etc.)
  • Planar Lux Sensor for quantitative analysis of near-field illuminance
  • Luminance Camera Sensor for rapid, high-accuracy luminance images at multiple viewing directions. Includes ray history sensor feature to restore ray paths that correspond to region selections on specific luminance camera images; this functionality allows you to efficiently troubleshoot signal lighting optical systems, by correlating regions in the luminance image with specific ray paths, and thereby the respective optical surfaces. As a result, the number of design iterations that are needed to meet lit appearance, in addition to regulation compliance, can be significantly reduced

You can easily export your model to LucidShape to perform other tasks, including simulation and visualization of lit and unlit appearance.

Light Guide Design Module

The Light Guide Design Module helps automate the construction, analysis and optimization of light pipes and their extraction features to improve light output.

Example Model Library

A robust example model library, with intuitive features for browsing, searching and filtering content, helps you get a head start on model creation and analysis tasks.
