thx for the explanation. I know x3d is better, but I have to convert it, because the 3D printer only accepts wrl format.
I tried to convert it, but it looks quite complicated for me, even if I look at your description.
Here is a link to the file: www.bestaltmed.at/slicer/modelcullfrontface2.wrl.zip
Can you tell me please, which part I have to remove and how I should add the #VRML V2.0 utf8 to get a working wrl file?
I was looking inputonly,... but I did not found anything.

> Note that conversion from X3D to VRML inherently means loosing some things. VRML (2.0, and 1.0 even more so) is an older standard, and just cannot express many things that are possible in X3D. I would advise to use modern tools that can work with X3D. Converting your models from X3D to VRML is a little step backward...

E.g. view3dscene allows to do this (http://castle-engine.sourceforge.net/view3dscene.php , conversion can be done by menu items or command-line options http://castle-engine.sourceforge.net/view3dscene.php#section_converting ). And probably all other converters mentioned in a link from Roland, http://www.web3d.org/x3d/content/examples/X3dResources.html#Conversions , as far as I know at least InstantReality can convert between encodings.
