LEDAS Releases 3D Comparison Technology to the B2B Market

LGC components available now for integration into engineering software

LEDAS, a developer of engineering software and a provider of software development services for the CAD/CAM/CAE/PDM/PLM market, today announced the first commercial release of its LEDAS Geometry Comparison (LGC) technology. As a component product, LGC is ready for integration into existing and developing B2B (business to business) software that interoperates with CAD models.

How LEDAS Geometry Comparison Works

LEDAS Geometry Comparison makes it easy to compare 3D models and clearly pinpoint all of the differences between them, which are shown as groups of modified faces. LGC maps topological elements of two 3D models and restores their associativity, allowing attributes, parameters, and constraints to be translated from one model to another. Built-in adjustment technology makes it possible for LGC to compare models that even were translated (moved) and rotated with respect to each other.

The software supports an extensible set of open and proprietary 3D part and assembly CAD formats. The cross-platform LGC code runs on 32- and 64-bit Windows and Linux, in both traditional and parallel MPI (message passing interface) versions. The LGC application programming interface is tuned for work in the cloud, making the integration of LGC into customers’ cloud-based systems as simple as possible.

“We consider LGC a must-have tool for the areas of engineering that deal with the modification, conversion, tessellation, and import/export of 3D CAD data,” said Alexey Ershov, CEO of LEDAS.

The Benefits of LGC

LEDAS cooperates with start-ups and market leaders, and provides beneficial licensing to early adopters of LGC technology. LGC benefits developers in these scenarios:
  • When collaborating with clients, LGC is crucial for comparing models following exports and imports between differing CAD systems
  • In inter-departmental design work, companies benefit when LGC checks updated models generated by in-office CAD systems
  • As a cornerstone of automated testing of software for generating 3D models, LGC’s tolerance control distinguishes between otherwise unnoticed modifications

“Several PDM (product data management) vendors have already shown interest in applying LGC to revision control, and so we have been working with them to integrate LGC into their products,” said Alexey Ershov. “Companies can evaluate the capabilities of LGC by downloading our free demo application from the LEDAS Web site.”

LEDAS is a private, employee-owned software company founded in 1999. It is the well-known developer of constraint-based tools and component technologies for the CAD, CAM, CAE, and PDM markets. LEDAS provides R&D and consulting services in the field of engineering software. More information about LEDAS is available at www.ledas.com.
