MCADCafe e-Magazine: ASCON Releases Geometric Kernel As CAD Component
May 21st, 2012 by Jeff Rowe
ASCON Group, developer and integrator of professional MCAD and PLM solutions, announced that it is making public its proprietary geometry kernel C3D as the foundation for creating computer-aided design systems and applications. The kernel is also well suited for designing computer-aided engineering (CAE) software, computer-aided manufacturing (CAM) programs for CNC machines, and modeling of engineering processes for product lifecycle management (PLM).
Development of the geometric kernel began in 1995, and then in 2000 ASCON released KOMPAS-3D v5.9, the first computer-aided design software system based on its C3D. Since then, the company has updated the kernel, and is now launching it as a separate product for the CAD component market. It handles all aspects of a CAD system: 2D drawing and sketching, 3D hybrid and solid modeling, parametric constraints, and translation.
“The decision to open access to our technology was the next logical step in our on-going development of the geometric kernel,” said Maxim Bogdanov, CEO of ASCON. “We are confident in the quality of C3D. For more than a decade, it has been the basis of our own line of successful CAD/CAM software.
“We see great prospects for its use, as new players appear on the market needing components for their CAD systems,” he added. “Standard 2D systems will inevitably switch to 3D, and consequently require a fundamental change to the core of the systems — or else find a replacement. The CAD component market is changing, and so there is a place for a Russian company with 17 years experience in geometric kernel development, and whose mathematical quality is recognized throughout the world.”
The main feature of ASCON kernel is that it is complete. The core of C3D combines everything necessary for the development of application solutions, as follows:
C3D Modeler is the geometric modeler with functions for 3D solid and hybrid modeling, sketching, and 2D drawing
C3D Solver is the parametric constraints solver with functions for creating and solving parametric constraints on 2D and 3D geometry
C3D Converter is the translator module that reads and writes geometric models in all primary exchange formats
Potential users for the C3D kernel are developers of CAD, CAM, and CAE systems and related applications requiring the processing of 3D models and 2D graphics. Among them are large industrial companies who often create software for internal use. Third-party developers can use the ASCON kernel to extend functions and abilities, increase performance and reliability, quickly create 3D modelers based on existing 2D systems, and reduce cost of development of their products.
Even before C3D was released officially, an early tester was already putting it to real-world use. “We were among the first to work with ASCON’s geometric modeling kernel,” explained Andrew Lovygin, CEO of LO CNITI and the official distributor of Esprit CAM in Russia. “In just four months, we embedded a full 3D solid modeler in our CAM system. Our choice of C3D was driven by ASCON’s flexible pricing policy and quality technical support. I am confident that ASCON will achieve excellent results with its kernel on the international market.”
C3D was first announced in April at the Congress On the Future of Engineering Software (COFES). C3D kernel is available now for limited licensing based on individual requests. Full access will be opened in January, 2013.
Commentary By Jeffrey Rowe, Editor
When you think of geometric modeling kernels, does anything immediately come to mind? For most of us who have been long enough, the ones probably at the forefront are ACIS and CGM (owned by Spatial Corp., a part of Dassault Systemes) and Parasolid (owned by Siemens PLM Software). Now, though, ASCON has entered the arena.
There was a time when geometric modeling kernels were the keystones of the MCAD industry. Most CAD vendors then relied, at least to some degree, and licensed them as engines for making their software applications go. While newly developed and released kernels were a good thing, some CAD developers felt that they were held hostage by the release cycles of their geometric kernel developers.
Times have changed, though. Today, an increasing number of vendors have undertaken the enormous task of developing, maintaining, and supporting their own geometric kernels. However, not all CAD vendors have gone the independent route, because it is such a huge and costly undertaking. However, I’ve also been impressed with how loyal many kernel customers have been over the long haul. Admittedly, though, changing kernels mid-stream is not an easy thing to do.
Today, as has been the case for quite some time, two of the major major players in the geometric kernel market are ACIS (owned by Dassault) and Parasolid (owned by Siemens PLM Software), but, of course , there are others, such as ASCON’s C3D. I’ve thought it ironic that SolidWorks (also a Dassault company) uses Parasolid from a Dassault competitor as its underlying geometric engine, and not ACIS (although it will eventually use Spatial’s CGM somewhere down the road), but that’s another story.
Simply put, geometric modeling kernels are the software components that make 3D solid modeling possible. Geometric modeling is one of the three legs of the triad that makes CAD possible – the other two being design and computer graphics. Geometric models are what make CAD really useful beyond basic drafting purposes and for engineering applications, as well. For them to be truly useful, geometric models must be unambiguous representations of objects. This demands that the 3D model satisfy comprehensive engineering functions from documentation (drawings) to simulation/analysis to manufacturing. That’s a pretty tall order, but is absolutely essential for the utility of CAD data that can be repurposed.
So, how significant or insignificant are software components, including geometric modeling kernels today? While it’s true that few users really care about the origin of the modeling kernel in their CAD tool, software component kernels are still relevant and significant for the following reasons:
Maybe geometric kernels don’t get quite the attention that they used to, but they remain an essential component (literally) for moving the MCAD industry forward. They have been and will remain a vital part of the MCAD industry for a long time to come.
3D software components and the vendors that supply them will continue to be in business for a long time to come. As they were in the past, software components will remain significant and relevant into the future for the MCAD industry. At some time in the near future, I’ll compare the specs and capabilities of ASCON’s C3D, Spatial’s ACIS and CGM, and Siemens’ Parasolid, just to see how they stack up feature-for-feature side-by-side. I’ll tell you what I find out.
