C3Day India 2026, held in Pune on September 8, brought together engineering software developers, CAD/CAM/CAE/BIM professionals, technology experts, and members of the C3D Labs community for an evening focused on the development of modern engineering applications.
The event, organized by C3D Labs, was designed specifically for CAD/CAM/CAE/BIM software developers, CTOs, technical leads, and companies developing their own 2D and 3D engineering applications. The event agenda focused on C3D Labs’ geometric kernel, C3D Toolkit components, customer experiences, and rapid CAD application development.
The Pune event provided a useful opportunity to understand how a geometric kernel and specialized software components can become the foundation for developing sophisticated engineering applications.
C3D Labs: Three Decades of Engineering Software Expertise
The event opened with Oksana Lobodanova, Head of Marketing, C3D Labs, who presented an overview of the company’s experience in engineering software development and global CAD/EDA/CAE customer support.
Oksana also highlighted C3D Labs’ journey since 1995 and the company’s three decades of development in geometric modelling technology. The presentation provided an interesting background on the work of Nikolai Golovanov and the development of the C3D geometric kernel.
One of the examples discussed was KOMPAS-3D, the widely used 3D CAD system from ASCON, which is built using C3D Kernel technology.

Oksana also spoke about opportunities in India and the potential for collaboration with Indian engineering software developers. C3D Labs sees India as an important market for engineering software development and is open to long-term partnerships and joint development initiatives.
Understanding C3D Toolkit
Denis Statsenko, Head of Product Marketing, C3D Labs, provided a detailed overview of C3D Toolkit, explaining how its software components can help developers build independent CAD/CAM/CAE/BIM applications.
He explained the different capabilities available within the C3D ecosystem, including C3D Modeler, C3D Vision, C3D FairCurve, C3D B-Shaper, C3D Solver, C3D Collision Detection, C3D Web Version, C3D Converter and C3D PolyShaper.
The presentation also provided a broader understanding of how CAD, CAM and CAE applications are structured and where geometric modelling, visualization, data conversion, simulation and other components fit within an engineering software architecture.

The C3D Labs event page describes C3D Toolkit as a set of software components intended to help developers build CAD/CAM/CAE/BIM solutions and develop complex, independent engineering software.
Real-World Applications Across Engineering Software
Daniil Kalmykov, Sales Support Engineer, C3D Labs, presented customer stories demonstrating how C3D technology is being used across different engineering software applications.
The examples covered a wide range of industries and software categories, including KOMPAS-3D by ASCON, CIZEN by Mubitek, Delta Design for EDA, VR Concept for AR/VR, ADEM and Techtran for CAM, CYPE and Renga for BIM/AEC, SIBUR Digital, Soyuz PLM, FlowVision and PASS EQUIP for CAE, among others.
The presentation helped demonstrate that a geometric kernel is not limited to traditional mechanical CAD. The same underlying technology can support applications across CAD, EDA, CAM, CAE, BIM, PLM and other engineering domains.
A particularly interesting example was Imaginatix, a cloud CAD solution developed using C3D technology. The examples of ADEM CAD/CAM and SIBUR Digital also demonstrated how C3D-based technology can be applied to specialized manufacturing and industrial engineering workflows.

KOMPAS-3D: A Customer Success Story
Alexander Rybinskiy, Head of International Sales Department at ASCON, presented the ASCON customer story and explained how C3D Labs technology is used in the development of KOMPAS-3D.
The presentation offered developers an opportunity to understand how a commercial CAD platform can utilize geometric kernel technology to deliver sophisticated 3D modelling capabilities for users across sectors such as Aerospace and Defense, Automotive, Marine and Consumer Products.

Building a Custom Operator with C3D Kernel
Aniruddha Raste, Founder of Engenext and Om Parkar, Software Developer at Engenext, presented “Building a Custom Operator with C3D Kernel.”
The presentation was particularly relevant for developers looking to create customized CAD functionality. It demonstrated how C3D geometric kernel can be used as a foundation for developing specialized operators and engineering applications rather than requiring developers to build fundamental geometric functionality from scratch.

Hands-On C3D Toolkit Workshop
One of the highlights of C3Day India 2026 was the hands-on workshop conducted by Maksim Kulagin, Head of Technical Support & Testing, C3D Labs.
The workshop focused on rapid CAD application development powered by C3D Toolkit, giving participants a practical look at how the technology can be used.
Maksim demonstrated the toolkit and licensing process, followed by live coding examples. Participants got to see how 3D objects are represented using boundary representation, as well as examples of creating and editing geometry.
The session also explored questions around construction history and how developers can work with geometric data at the kernel level.
The hands-on nature of the workshop made it particularly relevant for the developer audience. Rather than simply presenting product capabilities, the session showed how developers can actually work with the technology and begin building applications around it.
The official event agenda allocated a full hour to the workshop, followed by a Q&A session and dinner.
A Developer-Focused C3D Community Event
Unlike a conventional software user conference, C3Day India 2026 had a strong focus on the technology behind engineering software development.
The event brought together people who build engineering applications and those interested in understanding how technologies such as geometric kernels, modelling components, visualization, simulation and data conversion can be combined to create specialized CAD/CAM/CAE/BIM solutions.
The strong participation from developers and technology professionals also created opportunities for discussions around India’s growing engineering software development ecosystem.
The event format — presentations, customer stories, technical demonstrations, a hands-on workshop and Q&A — provided a good balance between business perspective and technical learning.
Conclusion
C3Day India 2026 offered an insightful look at the technology and expertise behind modern engineering software development. From the history of C3D Labs and its geometric kernel to customer applications, custom development and hands-on programming, the event demonstrated the breadth of possibilities available to engineering software developers.
For developers and technology leaders building CAD/CAM/CAE/BIM applications, the event provided valuable insights into how established geometric technology can accelerate application development while allowing companies to focus their own engineering expertise on differentiated functionality.
The event concluded with networking and dinner, giving attendees an opportunity to continue discussions with the C3D Labs team, speakers, developers and fellow engineering software professionals.
Overall, C3Day India 2026 was a valuable developer-focused event that brought the C3D Labs technology ecosystem closer to India’s growing engineering software development community.
