Hi,I encountered a problem when using DrawLine2D or any other 2D drawing function with Open GL activated. This problem was already there in R12:
All objects, polygon objects as well as simple objects like cubes, will be displayed wrong as soon as just one 2D line is drawn. The image shows the kind of error (right hand). Faces that are directed in x or z direction are displayed as if the normals are reversed. But remember: it's a standard cube!

Any ideas?

Ok, the problem is that the 2D drawing functions disable the Z buffer. Our OpenGL developer recommends to use the non-2D functions in camera space instead. If this doesn't work you can alternatively call bd- >SetDepth(TRUE) to enable the Z buffer again.

ok, bd->SetDepth() does it when calling after 2D drawing. But this function is available only in R13, isn't it?

Unfortunatly, yes. So for R12 I'm afraid you have to use the non-2D drawing functions.
