Hello, I saved my parts with the name of the project included. For example, spaceship_frontpanel, spaceship_engine, etc. If I save the files in STL format using "save as copy and open" and rename the files or just save in STL format using the same name but later rename under Windows, will the original name of the files be somehow embedded in the STL file? For example, spaceship_frontpanel save as A.stl, spaceship_engine save as B.stl. I am sending the STL files to a company for 3D printing but I do not want them to know what I am working on. Can they find out the original name and folder based on the STL files I sent to them?
If you are saving in ASCII format there is only triangles data and STL file name. You can simply open the file in the notepad to check:
EDIT: For the binary format there is 80 bytes header (reference: STL (file format) - Wikipedia). The stl file name is inluded in the header (not the original body). Below is a sample header from the binary stl:
There is however an issue when you exporting the assembly as it automatically appends the component name into the file name and header. So you can obfuscate the top assembly but not components.
So as the summary just Save As STL and give it a random name for parts (do not save as default and then rename as the original file name will be included as solid body in the header). You still will have component names included in the header for assemblies.
There is however possible to write custom exporter and include whatever information you need (including the random naming).
