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 2019.06 offers the following new features.

Expanded Surface Sensor

The LucidShape Surface Sensor feature supports accurate analyses of illuminance and irradiance on curved surfaces. This cutting-edge feature enables designers to evaluate performance of highly complex or curved lamp components, such as those used in interior ambient illumination, light guide surfaces, and stylized headlamps and tail lamps. The surface sensor feature has been expanded with more powerful and flexible analysis options that give designers the ability to:

  • Measure luminous flux on any geometry when you combine the surface sensor is combined with the lumen sensor material. Geometry can consist of a single surface with one or more faces or multiple surfaces, and surfaces can be planar or curved.
  • Display results of the surface sensor with lumen sensor material in 3D in the part design view.
  • Set separate analysis options for the lux sensor and lumen sensor in the same simulation to efficiently analyze lux sensor and lumen sensor results.
  • Specify the criteria for light data measurements such as intersection point, maximum value (including its XYZ position), or integral value to streamline analyses and tailor the output to fit the application. It is also possible to control the scope of the measurement-to cover a single face, for example, or the entire lumen sensor.
  • Analyze, measure, and visualize color effects directly in the part design view.


Ray Result Filtering by Surface

A new Surface Result Filter allows designers to filter the rays recorded on a sensor based on their interactions with specified surfaces. For example, designers can record only rays that hit a surface last, rays that hit at least one of the specified surfaces, or rays that hit all of the specified surfaces during a simulation. This feature provides an efficient way to identify and troubleshoot parts that interfere with light distribution.


Enhancements to the Light Guide Design Module

The Light Guide Design Module saves designers time with groundbreaking illumination optimization features that automatically design light guides and their extraction features. New capabilities in this release include:

  • New options for prism items that enable designers to save portions of a design and apply them as a starting point for a new light guide, which could have a different number of prisms, if desired.
  • An option that allows designers to set non-uniform spacing of prisms according to a desired extraction density (XWidth) curve, which is useful when there are design constraints on the smallest XWidth size.
  • The ability to detect "ambiguous" surface profiles using end gaps, as well as the ability to make intelligent profile rotation guesses based on nearest "good" neighbor profiles.
  • New Ambiguous Surface Profiles test using end gaps, as well as intelligent ambiguous profile rotation guesses based on nearest "good" neighbor profiles.
  • XYZ and LMN light target direction list options, which are easier to use than HV space, for example, to aim light from a light guide to a specific region in an interior lighting design application.
  • Simplified view setup that allows designers to obtain parameter values by selecting an axis system.
  • The ability to optimize for flux uniformity with prism items other than XWidth, which provides flexibility for special applications.

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.
