How to save drawing to be viewed only?

There really has to be a way of password protecting a locked group...because all you'd then have to do it group the entire model and lock it.

As things stand, a locked object cannot be copied...and if you save it and then re-import it, it comes back in still locked....getting you nowhere. All that leaves is disabling CAD export.

Alan,
are you saying there is a way to lock a group with a password? it sounds the simplest, rather than exporting drawings to other formats and hoping the person has a program that will open it. can you tell me how it's done?

Just make the drawing 600x400 so that it isn't worth saving by anybody.

I'd say it's pretty much impossible to make a drawing so that people can't copy it. Even if you go to the lengths of making it save disabled, anyone with a tiny knowledge of computers could just save a screenshot of it and get it that way.

IMO if a drawing is so precious to you that you don't want anyone else to have it, you don't share it.

No, what he says there should be a way...

And yes, the problem is not only opening and editing a (still not possible, pasword protected) locked model but also exporting (at leat to vector format) should be disabled.

This feature request has recurrently arised (especially since the free version was firt released) already and I don't think it would be very hard to program.

I would guess that it is not as easy as it seems. SU would probably need a totally new, encrypted file format. I don't know if it is still so, but Adobe used to warn users of Acrobat that using the password-protection in it could rather easily be circumvented by third-party programmers.

Theres been a new file format with each new version of SU. Could be tricky with people using older versions of SU though.

I tend not to give clients the model at all, they wouldn't know how to use SU anyway. Just give them an animation file.

Hey, and what's about SU viewer ? Does it still exist ? ( I've downloaded the last version for a while)
That the way I send skp files to some customers, but animations possibilities are restrained.

MALAISE ( if that may help )

For the SU Viewer you still need to send an skp file which could be opened in SU if someone wanted to change anything.
