This is a proper moment to read about our history. Let me put some points here.

• 2019 LEDAS celebrates its 20th anniversary by moving to a new own 1,000-square-meter headquarters office at Academpark.
• 2017 LEDAS releases its LEDAS Cloud Platform (LCP) as an easy way to build Web-based CAD solutions.
• 2016 LEDAS signs a long-term cooperation agreement with a major US-based digital dentistry company.
• 2015 LEDAS lands its biggest service contract to date for developing a full-scale Web solution in the area of building information modeling (BIM)
• 2011 LEDAS sells some of its intellectual property and staff to Bricsys NV, including its LGS 2D/3D geometric solver. After the sale of IP rights concludes, LEDAS renews its top management and pivots the company to focus on high-end R&D ...

As of today, March 31, there are only 9 confirmed cases of coronavirus in the city and region of Novosibirsk, near where the office of LEDAS is located. As the disease began spreading in other parts of Russia (initially in Moscow), Novosibirsk State University two weeks ago shifted to distance learning. Teachers received suggestions as how to organize remote lessons for students using a variety of opportunities:

• Hold remote conferences via the Internet using such platforms as Google Meet, Zoom, and Skype
• Record video lectures and seminars from empty classrooms at the university
• Record videos from home using cameras on smartphones
• Send materials and homework tasks by email and get the results

LEDAS is proud of its strong connection to Novosibirsk State University and other ...

A dozen LEDAS programmers took part in a C++ event a month ago in our city of Novosibirsk, which was happily organized before the spread of any COVID-19. C++ has become a very complex programming language with a long history stretching back to 1983, and so it was tricky for event organizers to arrange talks that appealed to every kind of developer. Perhaps the easiest thing to talk about was new standards, and this year this was possible as the new C++ 20 standard is on its way.

Following the event, we wanted to know what our LEDAS programmers thought about C++ 20, and now we have their answers available to share with you.

C++ 20 highlights four major new features: concepts, ranges, coroutines, and modules. Here is how our ...

These days humanity faces one of the biggest threats and challenges in decades with the pandemic of a deadly virus, which has already become a personal tragedy for thousands all over the world.

LEDAS is, so far, fortunate in experiencing no cases of COVID-19 in our neighbourhood. We decided nevertheless to improve our capabilities for working remotely. By working remotely, we contribute to social distancing, which is essential to “flattening the curve,” the primary goal now identified by health experts in reducing the load on our hospitals.

Working remotely is also important to keeping the economy working, as a complete shutdown would cause great losses in output and revenues, and, as a result, possibly in more lives lost.

An efficient infrastructure for remote work implies high-speed Internet connections, as well ...

One of the important components of CAD is the geometric constraint solver. Since the early 1990s, the field was monopolized by a British company, D-Cubed, now a division of Siemens Digital Industries Software (formerly Siemens PLM Software). In 2001, LEDAS began to develop geometric constraint solvers for 2D and 3D geometry, called LGS 2D and LGS 3D. They were successfully brought to the global market, and licensed by dozens of CAD companies in USA, Europe, Japan, Korea, China, and Russia.

While working on LGS, the programmers at LEDAS developed similar software for Dassault Systèmes, which were integrated into CATIA and so are used by hundreds of thousands engineers in corporations like Toyota, Honda, Airbus, and Boeing. Much later, LEDAS was asked to develop constraint solvers that ...

Companies invite LEDAS to outsource their hard engineering software projects because in our team they find an effective balance between in-house and extendable competencies, the ability to deal with innovations, reliability and quality of the resulting solutions, high level of communication, and reasonable pricing. These advantages have been formed at LEDAS over its 20-year history of implementing knowledge-intensive industrial software development projects.

Near the end of the 1990s, a team of mathematicians and computer scientists from Novosibirsk Academic Lab were involved in small research projects for Dassault Systèmes. A manager at Dassault recommended that we establish ourselves as a private company, as operating as a business would be better suited to developing industrial-scale projects. And so LEDAS, Ltd. was founded on April 1,1999.

The subsequent history of ...
