LEDAS Blog

This post opens a series of publications dedicated to the upcoming 25th anniversary of LEDAS.

In our era, which in many respects is not much different from the era of two thousand years ago, it is still important to periodically ask the question of who we are.

To get at least a partial answer to this question, which worries not only philosophers who occasionally think about it, but also always active recruiters, we conducted a survey of company employees.

And before we get to the strings, let's find out at what age and in what language the developers of CAD components and solvers begin programming.

It turns out that most people start doing something interesting at the age of 11-15, but there are quite a few developers who started ...

Our Autumn Update

Nov 27, 2023 Alexey Ershov

Hi there! Let me report to you our recent activities, from late summer to mid-autumn. We have been busy!

It was in August that we launched a new project in the area of digital medicine. It is somewhat different from our usual work in digital healthcare in that it combines software with hardware development. It is the innovative hardware part to which we are paying a lot of attention. Although I cannot reveal the name of the client, I can tell you that we are working on a start-up project initiated by a team already established as successful entrepreneurs in Industry 4.0.

September was the month in which we organized a week-long series of technical meetings in Italy. Together with one of our biggest customers, we discussed their ambitious ...

The Book Club at LEDAS

There are exactly 42 books on our reading list, something Douglas Adams would approve of!

Nov 14, 2023 Ilya Lichman

Just as it is hard to clap with one hand, it's hard to develop mathematical algorithms only by reading technical articles. And so despite the fact that we regularly read and write about C++ and CAD (for instance, about constraint solvers and plugins), we have regular book club meetings at our company at which we read fiction and non-fiction.

Perhaps one day we'll make a list of our favorite technical books on designing complex and reliable systems and must-read articles on mathematical algorithms, but for today we'd like to share a list of the books that interest us.

Back in 2018, LEDAS Book Club meetings were held in person, but gradually we've come to realize that it's much more convenient to meet online. As of 2020, ...

Some parts of the history of CAD are intertwined with card games and other fun activities, perhaps more than CAD/CAE/CAM users and developers realize. One of the most famous events occurred in the late 1980s when Jon Hirschtick trained the MIT Black Jack team.

Using his techniques, the team won millions in Las Vegas, which then went on to blacklist him from their casinos. You may have seen the movie or TV series about his amazing journey, going from university to winning at casinos, and then using $1 million of his winnings in 1993 to create SolidWorks, the first – and then best-selling – mid-range mechanical CAD package to run on Windows (now owned by Dassault Systѐmes). Later, he went on to lead the development of Onshape, now owned by PTC. You ...

Salutations à Tous les Lecteurs Francophones!

Greetings to all French-speaking readers!

Feb 16, 2022 Alexey Ershov

In the history of LEDAS, a big role was played by software companies in France. Our company got its start in 1999 by landing work with French CAD vendors. Since then, LEDAS has provided B2B R&D (business-to-business research and development) services to several well-known CAD and CAM companies in France in the field of computational geometry. This early experience helped shape the corporate culture of engineering software development at LEDAS.

Contracts with customers from France have been the longest in the history of LEDAS, two of which worked with us for over a decade. For Dassault Systèmes, LEDAS helped develop geometric constraint solvers and a 3D modeling kernel used by the CATIA mechanical design system. Another contract was done with an award-winning CAM company in the aerospace industry. ...

Pivot Points In the Story of LEDAS

Mar 30, 2021 Alexey Ershov

It’s just before our 22nd anniversary on April 1, and looking back at the history of LEDAS, I see that the first years from each decade were, for our company, the really important ones. Often, these years started new stories and finalized old ones.

Arguably, 2011 was the most pivotal year in LEDAS’ history. Let me list the top five events that happened to our company ten years ago:

  1. Top management changed completely when co-founder David Levin stepped back as CEO and took on the role of Chairman of the Board. A new generation of young managers, aged around 30 years old, now occupied the CEO, CTO, and COO positions.
  2. Thanks to advice from an industry mate, LEDAS decided to focus mostly on high-quality software R&D (research and ...

Today is the 21st anniversary of LEDAS!

Apr 01, 2020 Alexey Ershov
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 ...

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 ...
