Reverse Engineering Software / Inspection Analysis Software (PolyWorks)

PolyWorks/Modeler ™

Class A Polygonal Modeling & Fast Surfacing for Manufacturing Applications
PolyWorks/Modeler™ is a comprehensive software solution for creating accurate and smooth polygonal models and NURBS surfaces from high-density point clouds. Preferred by automotive design studios worldwide, PolyWorks/Modeler™ is the only software solution that has demonstrated the capability of creating class A polygonal models for stringent polygonal manufacturing applications such as 3-axis & 5-axis milling, aerodynamic simulation, and digital review. PolyWorks/Modeler™ also offers a powerful rapid surfacing methodology that delivers the most usable NURBS surfaces in CAD software such as CATIA and UG.

PolyWorks/Modeler™ allows you to:

Generate manufacturable class A polygonal models

• Transform aligned point clouds into highly accurate polygonal models using PolyWorks' unique tolerance-based adaptive meshing technology.
• Reconstruct perfect polygonal features from imperfectly digitized geometry.
• Apply all typical CAD operations directly to polygonal models and prepare these models for a wide variety of manufacturing applications such as milling, rapid prototyping, reverse engineering, inspection, CFD & FEA, digital review, etc.

Create smooth and logical NURBS surfaces easily editable in CAD software

• Use automatic feature-tracking tools to quickly create curve networks containing center curves, fillet tangent lines, sharp edge curves, etc. Curves can also be extracted interactively using only one mouse click.
• Constrain the automatic surfacing process to predefined curves in order to create more logical curve networks.
• Control the rigidity of the fitted NURBS surfaces, mimicking a sheet metal material for getting super-smooth surfaces without ripples, or a plastic material to closely follow subtle polygonal details.
• Optimize your subsequent efforts in the downstream CAD application by minimizing the number of control points and patches, increasing the smoothness of patches, and easily creating perfect feature curves.

3D Digitizing

• PolyWorks handles organized and unorganized high-density point clouds produced by all laser scanners, fringe-projection systems, LIDAR scanners, etc.
• It also offers several plug-ins that allow direct scanning from within its user interface.
• Finally, PolyWorks is optimized to handle datasets of up to 100 million points efficiently without subsampling.

PolyWorks/Inspector ™

The World's #1 Point Cloud Inspection Solution in the Manufacturing Community
PolyWorks/Inspector™ is a powerful software solution that uses high-density point clouds and contact-probe datasets to control the quality of parts and tools at every phase of your manufacturing process. Today, major automotive and aeronautic OEMs and tier-one suppliers worldwide use PolyWorks/Inspector™ as their standard point cloud inspection software for prototype, first-article, manufactured, and assembled parts inspection.

PolyWorks/Inspector™ allows you to:

The measurement process is based on the principle of optical triangulationand benefits from the precision of light. The automatically generated data images are analyzed and evaluated within seconds by digital image processing. The consistent explitation of redundant information covers the result statistically. Without direct contact to the object and being materially independent, the 3D-digitizing of arbitrary object, such as work pieces, models, moulds, plastics, human body parts, component damage, etc. can be realized for a variety of applications e.g:

• Use high-density point clouds and contact-probe datasets of digitized prototype parts & assemblies to quickly identify deformations and to fix problems in the earlier stage of the manufacturing process.
• Approve your manufacturing process by fully inspecting your first-assembled products.
• Monitor the production cycle by automatically measuring the wear of tools and quickly detecting any abrupt degradation in product quality.
• Verify the compliance of final manufactured and assembled products through sample check inspection using automated techniques.

Importing Objects: Data Objects & Reference Objects
Data objects consist of set of digitized points. PolyWorks/Inspector™ supports datasets produced by all high-density 3D digitizers, articulated arms with contact probes, laser trackers, and CMM. PolyWorks/Inspector™ also offers several plug-ins that allow direct scanning and probing from within its user interface.

Reference objects describe a surface and can consist of a NURBS-based models or polygonal mesh. PolyWorks/Inspector supports CATIA V4 and V5, IGES, PRO/E, STEP, STL, UG, and VDA-FS file formats.
