Our Autumn Update

Ноя 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!

Ноя 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, ...

Will ChatGPT Replace Programmers At LEDAS?

Сен 12, 2023 Nikita Vorobyov

You must have heard of ChatGPT, that artificial intelligence chatbot developed by OpenAI. It interacts with humans in a conversational way by supporting queries made in natural languages.

For developers, ChatGPT’s most attractive feature is its ability to generate code in any programming language. But how useful is AI-generated code? Let's find out by asking ChatGPT to solve some simple tasks that arise in CAD development projects. (We conducted this study some time ago; since then, ChatGPT has perhaps become smarter.)

In our experiment, we asked ChatGPT to solve the following tasks:

  1. From scratch, write a geometric algorithm to find the intersection of two lines in 3D space
  2. Using an open source library, write a geometric algorithm to imprint a 3D solid
  3. Provide a brief guide ...

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 ...

LEDAS Opens New Office in Israel

Июл 24, 2023 Alexey Ershov

The LEDAS Group recently opened a new office in the metropolitan area of Tel Aviv. This location is in the central business district of Israel and will help us to better deal with customers in Israel and globally.

Israel is widely known as one of the world leaders in engineering software through the presence of big development offices of established CAD/CAM/CAE vendors, as well as startups. This makes the country a major hub of the world of engineering software.

We have a long history of working with Israeli companies. Starting in 2004, our very first license of the LGS constraint solver was made with an Israeli company, Proficiency, which today is part of ITI, a Wipro company.

At the other end of the timeline, our most recent agreement was ...

Grüße an alle deutschsprachigen Leser!

Greetings to all German-speaking readers!

Июн 29, 2023 Alexey Ershov

We’ve launched our Web site with a new language, this time in German. Through https://ledas.com/de/, we are making information about LEDAS services more visible to potential engineering, design, and manufacturing customers in Germany, Switzerland, Austria, and other German-speaking countries.

Germany is well-known as the leader of European manufacturing, and one of the leaders of manufacturing worldwide. As our company from the very beginning was focused on the European market of engineering software, we managed to get into contact with German businesses rather fast.

Case History: CAM Software Success

CAM (computer-aided manufacturing), including additive manufacturing, is one of our six areas of expertise, and it is the one with which we have been working with German firms the most.

Our biggest project to date was dedicated to machine ...

International Women's Day at a climbing wall

New interesting experience and a great time

Мар 30, 2023 Ilya Lichman
Designing and implementing mathematical algorithms for CAD/CAE/CAM has a lot in common with climbing a steep cliff. In both cases, we have to overcome obstacles and ourselves, find non-trivial solutions and hidden reserves. There is also a lot of fun in both of these very different actions.

Given this circumstance, we decided to celebrate International Women's Day at the climbing wall. The employees and their families got a new or expanded their existing climbing experience.

Interestingly, it's not as easy as it looks from the outside. However, this applies to almost any activity. After all, it is only when we start doing something that we realize why a colleague just couldn't "simply lift his leg and pull himself up on that ledge," as everyone ...

The field of digital medicine is the top grossing one for LEDAS. In the past 3-5 years, it has grown to represent close to one-third of our income. We have completed more than ten digital medical projects in different areas for the desktop and Web/cloud, and in the coming years we plan to broaden our portfolio in digital health solutions even further.

And so it was that in Jerusalem on 9-10 November, LEDAS took part in MIXiii, the annual Life Science & Health Tech Industries event for Israel. Our interest in MIXiii is explained by a LinkedIn article written by LEDAS founder David Levin we recently posted, “LEDAS covers 5 of 7 areas currently having highest potential in digital medicine: Orthopedics, Plastic & Reconstructive Surgery, Prostheses, Orthoses, and ...

Salutations à Tous les Lecteurs Francophones!

Greetings to all French-speaking readers!

Фев 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. ...
