What do you mean "it won't work"?
This functionality is covered by test cases, and works as expected - see bugs/vis/bug25783_1 for example.

vinit View1
vpoint p 50 -50 0
vdisplay p -2d topLeft 0 0 -osd

Beware that Aspect_TypeOfTriedronPosition flag defines only an origin of coordinate system, not it's orientation - it is always OY top and OX right.

Dear KGV,
My understanding is that Aspect_TypeOfTriedronPosition will also change the coordinate system orientation. Thank you for your important information.
Would you please add these information to document? it would be helpful for those who encounter problem in such situation.

The current documentation looks clear from my point of view.
If you thing that it can be improved - the patches are welcome!

OK, please close this issue, it's not so important to improve the document though it might be more clear to clarify the coordinate orientation.
