== Kernel market ==
The kernel market currently is dominated by [[Parasolid]] and [[Software:ACIS|ACIS]], which were introduced in the late 1980s. The latest kernel to enter the market is KCM. [[Engineering:ShapeManager|ShapeManager]] has no presence in the kernel licensing market and in 2001 [[Company:Autodesk|Autodesk]] clearly stated they were not going into this business.{{fact|date=April 2022}}

The world's newest geometric modeling kernel is [[Engineering:Russian Geometric Kernel|Russian Geometric Kernel]] owned by the Russian government, and it is not clear if it is going to be commercially available, despite offering unique features over the other kernels on the market.<ref>{{cite web|url=http://isicad.net/articles.php?article_num=16135 |title=Russian 3D-kernel RGK: Functionality, Advantages, and Integration |website=Isicad.net |date=2013-05-24 |access-date=2016-07-27}}</ref><ref>{{cite web|url=http://gfxspeak.com/2013/06/06/does-the-cad-world-need-another-geometry-kernel/ |title=Does the CAD world need another geometry kernel? |website=gfxspeak.com |date=2013-06-06 |access-date=2016-08-17}}</ref><ref>{{cite web
