Geometrical model structure editing
When editing the model structure one can create new groups (model structure tree nodes), delete, cut/copy to the exchange buffer or paste geometrical and structural objects (surfaces, meshes, curves, points and groups) from the exchange buffer.
Predefined groups (<Full model>, <Part>, <Workpiece>, <Fixtures>, <2D Geometry>), and all objects inside <2D Geometry> group cannot be deleted or cut into the exchange buffer. However copying the objects into the exchange buffer is possible without any limitations. Objects copied from <2D Geometry> will lose their connection with that environment, and if any subsequent changes made in the 2D geometry mode, these objects will remain unaltered.
