Re: Question CAD-to-GEANT interface (Vanessa)
Date: 23 Aug, 2007
From: John Apostolakis <John Apostolakis>

Dear Vanessa,

There is now a prototype capability for this, that utilises a commercial 
tool to convert a CAD file (generally STEP format) to an intermediate 
internal format. 
  --> The tool is called "ST Viewer" and it is created and sold by 
STEPtools Inc
The file it creates contains approximate solids (used for its own 
visualisation).   We have created tools to convert the files into files 
that can be read by the GDML reader.

This system does not have any information on the relevant material.  It 
also is best for a one or a few solids/volumes to which you will then 
give materials etc.

A more complete system is under develoment, but I do not currently have 
information when it will be released.

Best regards,
John Apostolakis

P.S. Since you appear to be posting from a personal account, could you 
please let us know the application domain of your simulation, and your 
affiliations.
