In 1995, ASCON made the decision to write its own geometric kernel when it began work on a new MCAD system known today as KOMPAS-3D. The three-dimensional modeling system was released commercially in 2000, but the kernel was used only by the company for its own software. In 2012, the company released the kernel to the engineering market as standalone product called C3D.

Over the decades, ASCON continually improved C3D in tandem with KOMPAS-3D. This list covers the most significant improvements made each year:

ASCON has been developing its geometric kernel for 20 years through improvements to its architecture, such as creating new functions, and updating previously implemented methods. With the unique experience it gained from the practical application of its KOMPAS-3D software running on tens of thousands of workstations, ASCON was able to introduce C3D to the market as a mature, standalone product. It is now developed and promoted through the C3D Labs division of the ASCON Group.

The Real History of the C3D Kernel


Yuri Kozulin, Head of C3D Modeler Department:

"All of our customers help us improve our products, and so they participate in the development roadmaps for the software. We appreciate it”

Andrey Penkin, Mathematician and Programmer:

"If a problem is unsolvable, that does not necessarily mean the assignment is impossible to complete"

Alexander Alakhverdyants, Mathematician and Programmer:

"Geometric kernels are few, and parametric solvers are even fewer. That is why C3D is so cool!"

Anna Ladilova, Mathematician and Programmer:

"C3D kernel development is much more interesting than writing code for known algorithms"
