What is new in version 6.0

DG Kernel is considered a new product. Most features of KernelCAD are supported. See Porting to DGK.

Improved support for parametric modeling using expanded and improved interface, new examples and documentation

Interface set has been redesigned to simplify and make it uniform across all technologies. Old interfaces are supported also

New .mdg file format is better suited for future development. The previus .glm format is still supported. It is possible to convert glm to mdg and vice versa

In the new interface (DG Interface) Section term has been replaced with Entity to follow closer the industry standard. There is no separate SceneItem notion in v6.0

New Geometry concept allows isolation of internal geometry of an object from its role in model hierarchy and its 3D placement and orientation

Transient Boolean property allows excluding an item or entity from save operations

Size of Object User Data has been increased to 64 bit

New DG Kernel runtime standalone installer gives an option of updating applications independently of DG Kernel

Rendering inside ClientDraw event handler is no longer suported. It is recommended to use regular model entities to add auxiliary objects to the scene. Details.
