I tried searching the forums for info on this and came up short, so I apologize in advance if this has been brought up before (which I'm sure it has).
I have a client who is asking for my Revit model. He is working with a lighting designer to do an exterior lighting study and basically knows the model exists and told the lighting guy that he can have it. Problem is, I don't think they technically "paid for" the model - they paid for the contract docs, which are the 2D prints that were generated from the model, not the model itself. If anyone else in my office was working on the project, it would've been done in 2D ACAD but since I was the project manager, I used Revit since that's my preference. I don't think that the client has any claim to the model, especially since the only reason it exists is because I like to work in Revit. So basically, I want tell him no.
The problem is, my boss wants me to send it. He's not technically savvy at all and I know he doesn't understand how much information is contained in the model. Is there a way to put a giant watermark in the Revit file or any other way to make it so they can't just steal everything?
Does anyone have any advice or links to other threads related to this? I'm concerned about the potential liability of sharing this information, especially since the client is a bit of a slimeball. I'd love to get some information to give to my boss to shed some light on why sending them the model is a terrible idea. Or conversely, something that would prove me wrong that says it isn't such a big deal (however I doubt this exists).
Thanks in advance.
