Hi Danny,

> What type of STL file does MoI export ascii or binary?

It can export either type, depending on the setting under Options > Import/Export > STL options > "File type". That can be set to either Binary or Ascii, the default is binary.

When you write out an STL, if there is just one object being exported and it has a name, MoI will write the object name into that header spot, if the object is not named it will write a generic "MoI Binary STL" for binary files, and a plain "solid OBJECT" label for ascii files.

Thanks again Michael, you make it all clear as usual.

Done a bit of research and it seems STL binary is the way to go as it produces a smaller file size.
Downloaded a free Hex editor http://mh-nexus.de/en/hxd/ and now I can write information just for that little bit of extra copyright security even though someone can bring the file into another polygon program and export it out again then all info will be overwritten, that's if they check the header that is.

Danny, are you distributing the files for viewing purposes only?

3D PDF has somewhat better security in that not many applications can actually read and use the data in a 3d PDF file. Its possible to disallow saving to STL when you create the 3D PDF so Adobe Reader can't export an STL. Obviously that does not help if someone has an app that can convert the data directly from the 3D PDF (Simlab for example).

Hi Chris,

> are you distributing the files for viewing purposes only?

It's for 3d printing purposes, I just wanted to put something in there in the case someone is sharing the file as their own.
Having Simlab composer myself, yes I would use 3d PDF if the file was for viewing purposes only.
