Hi,
I would like to export some pictures from Mathematica into vector
graphics format. I use Graphics3D container and
GeometricTransformation command to locate my arrows in 3D space. When
exporting this into eps or PDF file format the arrowheads get messed
up in the result file. However, using png everything seems fine. But
unfortunately I need this in vector format.
The other interesting thing: using Opacity command in the same
Graphics3D container results in the same effect but now inside
Mathematica. Wired!

Sample code demonstrating the problem:
Graphics3D[{Arrow[{{0, 0, 0}, {1, 0, 0}}],
Arrow[{{0, 0, 0}, {0, 1, 0}}], Blue, Arrow[{{0, 0, 0}, {0, 0, 1}}],
Pink, Arrow[{{-1, 1, 0}, {1, 1, 0}}],
GeometricTransformation[{Opacity[0.2], Black,
Arrow[{{0, 0, 0}, {1, 0, 1}}]},
TranslationTransform[{1, 1, 1}].RotationTransform[\[Pi], {0, 0,
1}]]}, Boxed -> False]

Export["pic.PDF", %]

I use Mathematica v7.0.0 - 32bit

Thx in advance!

Tibor
