How to protect my files from edited

Dear all,

Does it have any method to protect my files when I share it to others?
I mean other people can view & measure, but can’t change any components in files.
Please let me know, thank you and sorry for my horrible english.

nope… if you share the .skp, it’s editable by others.
there’s no way to password protect a sketchup file. (well, there might be a way… it’s just that no one has made it happen yet)

you can create a 3D PDF by using the SimLab 3D PDF Exporter or RPS 3D PDF plugins and than apply with e.g. Adobe Acrobat a password and according permissions.
