CGAL users discussion list

["Riedel, Torge" <>]

Hi,

Thank you very much. I think I searched in the wrong place.
Nevertheless I was not able to read my STL since it is in binary format. 
(File starts with "solid binary"). CGAL::read_STL continues reading it and 
does not stop. So maybe there is a check missing for binary format.

Any chance to read binary STL files with CGAL?

Kind regards
Torge
