The new version of XSIGNO allows to publish textured models as 3D PDF document.
I prepared a set of measurement example at the following location
http://xsigno.de/beispiele.html.
The examples have been tested with the most recent version of 9.3 of Acrobat Reader on Linux/Mac/Windows, please give me feedback if you experience problems with your version of Acrobat.
A user manual is now available online, see
