OpenGL representation in 2D view

With the implementation of the Open Graphics Language (OpenGL), you can now use a number of new features in the 2D top view. The OpenGL mode is turned off by default, you can activate it via menu "View". OpenGL allows:

When OpenGL is turned off, the order of the representation of overlapping objects is influenced by the import sequence without taken into account object height. A newly inserted object always overlaps an existing object even if its insertion height is lower as opposed to the existing one.

When OpenGL is turned on, the insertion height will influence the order of the representation of objects. The objects with greater heights always overlap underlying objects.

Attention! 
When exporting to DWG/DXF OpenGL is turned off. The representation of the objects in the resulting DWG/DXF file will correspond to the sequence of drawing / inserting (image left).
