Just published: two parts of a long paper "The Russian 3D-kernel"

You may have already heard about RGK - the project financed by the Russian government - aimed at building a geometric 3D-kernel. Until yesterday, all publications on RGK were in a meta-style, like for example a press-release  "RGK Russian Geometric Kernel Celebrates First Full-Featured Version" or my paper "Geometric Kernels and Irremovability of Presidents from Office".

Recently, the project (initiated in 2011) has come to the stage when the system became   operational and is under intensive integrated testing.  This enabled writing and publishing a rather detailed technological and technical overview of the achieved results.

The paper published yesterday and written in Russian consists of two parts. The first part  describes architecture, advantages, and facilities of integration the kernels with applications.  The second part presents functionality and the instruments to support building of standardized MCAD applications. The text of about twenty five A4 pages includes 14 pictures and three video clips. See couple examples below.  

isicad will definitely publish a slightly shortened English version before beginning of COFES Russia 2013, i.e. before May, 30.

Nine participants from Russian ASCON, Fidesys, LEDAS, and TopSystems will attend COFES 2013 in Arizona

The number of COFES participants from Russia and CIS is constantly increasing. Vladimir Malukh from LEDAS-isicad was the first Russian expert who in 2009 visited COFES when the event was hardly known in Russia and the CIS; see Vladimir's isicad paper "COFES – Wish you were here".  

Awareness of COFES drastically increased in Russia and the CIS when in fall 2010 Cyon Research together with LEDAS organized a COFES-isicad event in Moscow with a keynote and general active participation of Brad Holtz.  

In 2011, a list of COFES participants included five persons from Russian companies: three - from ASCON, one - from a multi-vendor reseller Consistent Software, and Dmitry Ushakov, who at that time was LEDAS CEO; see Dmitry's isicad paper "Get back! (Personal Impressions from COFES-2011)".

Active participation of ASCON in 2011 was not casual. The company is the largest Russian CAD and PLM vendor with a well-developed MCAD KOMPAS 3D and intensively extending PLM set; it successfully competes with Autodesk in the Russian & CIS market. In 2010-2011 ASCON began to internationalize its marketing and partnership activity as well as to invest into development of SaaS, mobility, and other hot trends. It is at COFES 2011 where the managers of ASCON established close partnerships for example with Lightwork: see my interview with Clive Davies: “ASCON is proving to be the ideal partner for Lightwork Design“.  This direction of ASCON’s development continued quite successfully which is illustrated, for example, in some isicad-papers such as «ASCON Releases DEXMA as a Competitor to PLM 360» , «ASCON’s Mobilezation: My impressions from the “White Nights” Forum», and other.

In 2012, ASCON again sent its three managers to COFES, and now – in 2013, CEO Maxim Bogdanov will attend Arizona for the third time, now accompanied by Sergey Evsikov, Vice-President, Sales (left) and Alexander Golikov, Founder (right):

Currently, ASCON feels like a mature international actor. The company is providing technical assistance to COFES Russia 2013  to be held in St. Petersburg six weeks after the event in Arizona. Today, ASCON is emphasizing its openly distributed original geometric kernel C3D  – the foundation of KOMPAS 3D, its above mentioned cloud PLM DEXMA, and its traditional-style large PLM+ERP environment.      

In 2012, COFES invited six persons from Russia and the CIS. Along with the people from ASCON, there were Dmitry Kondakov from IRISOFT (a large Russian VAR of PTC and some other vendors), Alexander Bausk from Ukrainian Nuclear Structures Research Lab, and Alexey Ershov, LEDAS CEO – see his isicad paper ”Arizona Dream: A detailed informal report on COFES-2012”.

Now about COFES 2013 which starts approximately in 4 weeks. You can meet there a record number of persons from Russia (seven). Two guys from ASCON were already mentioned above.

Another participant is Vladimir A. Levin,  ScD, professor, Moscow State University, department of Mechanics and Mathematics, Computational Mechanics. 

Vladimir’s main field of interest is developing mathematical models of strength analysis of bodies under finite strains. Total number of publications: over 235, including 4 monographs. Vladimir is the founder and the head of Fidesys – a start-up which positions itself as a provider of a new generation CAE system for strengthen analysis and associated problems. 


After my blogpost was published, Anatoly Vershinin, Fidesys CTO, joined Vladimir in his visit to Arizona. 

There will be three persons from Top Systems: CEO Sergey Kuraksin, CTO Sergey Kozlov, and Sergey Bikulov, executive director (from left to right):.

Top Systems's set of traditional CAD+PLM+ERP solutions is quite well developed and  recognized in the Russia / CIS market. The key product of Top Systems, its MCAD called T-FLEX, is characterized as one of the most developed parametric system in the world market: see a detailed paper by S.Kuraksin and S.Kozlov “The Power of T-FLEX CAD Parametric Modeling”: Part I and Part II. Interestingly a paper which compared  T-FLEX and SolidWorks (the comparison made by a Top Systems’ partner in Poland) has become and until now is the most visited isicad publication since launching the portal.

It is important to mention that Top Systems is actively involved (both in management and development ) into the building of a new geometric 3D modeler RGK within a big project funded by the Russian Government and being implemented by a distributed team from several development centers of Russia. I believe that today, by visiting COFES, Top Systems is making an active step towards international market.

This time, LEDAS will be represented by the company’s COO Nikolay Snytnikov – PhD, who despite his young age (30) has already passed through a hard many-year school of participation in a cool outsourcing project for Dassault Systems (as a developer and manager), and currently he is a manager of the LEDAS part of RGK - the Russian Geometric Kernel. Within RGK, LEDAS is responsible for the development  of Boolean operations,  fast NURBS library,  some parallelization tasks, and other hard problems (see “LEDAS Experts: How our Company is Involved in Developing Russian Geometric Kernel” by A.Ershov and N.Snytnikov). Nikolay's background is in parallel computing so his visit to NVIDIA GPU Technology Conference 2012 resulted not only in a series of best-read isicad reportages but seems to bring useful knowledge to the RGK project. Since LEDAS does not compete with any CAD vendor, the company is a partner of both Top Systems and ASCON; the latter has used LEDAS service to integrate direct modeling facilities into KOMPAS 3D and is now relying on  LEDAS support in distribution and commercialization of the C3D kernel.   

As an internationally recognized provider of components (such as geometric solvers, direct modeling modules, and other) and highly-qualified software development services, LEDAS is well-known to the global market. After selling its IP to Bricsys in 2011, LEDAS has been  focusing on services, and recently the company shareholders have established an US business entity to better serve its clients worldwide. On the other hand, competence, skills, experience, and creativity enabled LEDAS experts to formulate a number of new project/technology ideas related to some hot topics of engineering software such as interoperability, etc. Nikolay Snytnikov is going to Arizona to strengthen some existing contacts, to seek for the new service contracts, and to look for the partners interested in joint business projects. As a member of the editorial board and a fruitful writer for isicad.ru, Nilolay will also send us his reports from the Arizona event.

T-FLEX CAD – the King of Parametrization

This week, the Russian CAD/PLM company Top Systems celebrates its 20 years. Founded during difficult economic post-Sovient times by graduates of "STANKIN" (Moscow Technological University), Top Systems vigorously developed and released a full-scale parametric CAD called T-FLEX and soon after became one of the leaders of the market of CAD-related engineering software created in Russia. By now, Top Systems offers a broad spectrum of CAD+PLM solutions partially extended to the ERP direction.

See English publications about Top Systems in «The Russian MCAD Market» by Ralph Grabowski,  «T-FLEX Parametric CAD» by Deelip Menezes, as well as at http://www.tflex.com and www.isicad.net .

Today, isicad.ru published the first part of the article “T-FLEX CAD – the King of  Parametrization” (in Russian) in which two key founders of the company, Sergey Kuraksin (CEO) and Sergey Kozlov (CTO), in many details and with 32 video describe their approach and achievements regarding  parametrization  in T-FLEX CAD. The photo below taken from this paper shows the authors 20+ years ago.

Direct Modeling and other Top 10 topics of CAD/PLM at isicad.net

isicad.net is a modest English version of the most popular Russian CAD/PLM web resource isicad.ru published by LedasGroup. In contrast to the Russian version which aims to cover all key news and trends of the world and Russian markets of engineering software, isicad.net briefly reflects what happens at the Russian and CIS markets and from time to time publishes English translations of some original Russian articles related to the CAD/PLM domain.

Below you can see a list of Top 10 most visited articles.

Note that some of listed items are comparatively new and still have chances to move to the higher positions. By the way, an article “Direct Modeling -Who and Why Needs It? A Review of Competitive Technologies — by Dmitry Ushakov” published just couple days ago, judging by Google Analytics, can move to the very top of the list.    

A Hot Discussion around BIM at isicad.ru

This discussion was initiated by the article Revolutions in Design published in late September. Alexander Yampolsky, a practical and experienced engineer from Tula, a city close to Moscow, argued that collaborative work at integrated 3D-model is something unpractical for real-life AEC or at least premature. By today, the article got 40+ comments - most of them substantial and profound. People explained that BIM is today already broadly applied, that one should not consider BIM as artificial intelligence, compared BIM with PLM, gave some examples of successful approaches and technologies from MCAD that is hardly a more simple domain than AEC.

The discussion promptly continued by a series of bright and very well illustrated articles by Vladimir Talapov, a professor of Novosibirsk AEC University who is known as a strong supporter and practical promoter of BIM:

What affects deployment of BIM in Russia

Deployment of BIM: Conservatism and Common Sense

BIM or not BIM: that is the question?

BIM is actually Based on Whale (related to Frank Gehry’s sculpture of whale constructed in 1992 in Barcelona).

These articles provoked a not less stream of comments (about 50) than that of the article of A.Yampolsky – mostly supporting BIM but not always and not completely. One of the discussion lines was whether and why people today often identify BIM with Revit and Autodesk.

The Talapov’s series was followed by an article of Alexander Bausk from Ukraine entitled A less Optimistic Viewpoint at BIM in which a somewhat balanced opinion is presented.

At last (but not finally) isicad.ru published an article of Vladimir Malukh How MCAD is Used in AEC. Vladimir gives illustrated examples of how CATIA, SolidWorks, Pro/Engineer, Inventor, and KOMPAS-3D are fruitfully used in some serious industrial AEC projects. I believe that far beyond such examples AEC could adopt a lot from both design project decomposition and collaborative integration that by today are well developed and became common in MCAD. I would not be surprised to know about a profound isomorphism between design phases in MCAD and similar design actions directly or indirectly are or should be applied in AEC. To say nothing about a more or less recognized correspondence between BIM and PLM.

Note also that most of the people that contributed into the BIM discussion are professionals working in the domain for a long time. Also, it is worth noting that according to Google Analytics most of the recent isicad articles on BIM attracted a record number of the web site visitors.

Those who can read Russian or trust automatic translations can take a look at the above mentioned links. On the other hand, Alexander Bausk who, above all, contributed the AEC-BIM working group at COFES-Russia by his synchronous translation, plans to write for isicad.net a summary of our BIM discussion in English.

NB: besides Revit, it obviously could be modelled in many other systems!:).
