Inventor 2014 - Creating a mesh part that can't be converted back to solid

Hello,

 

I'm looking for a file format that I can save an assembly in that will prevent anyone from taking any measurements off of the body (to protect proprietary information).  So far I have created a simplified part from the entire .iam, then broken the link between the base parts and then I have saved that file as a .stl file thus making it a single, mesh object.  This file format works because it prevents any measurements from being taken and still would give a customer the ability to take the object, view it, and place it into their own assembly.

 

The problem seems to be that there are ways to convert this mesh object back into one with multiple faces and edges, whether it be through inventor or some other software (Rhino was one program I ran across.)

 

Is there a way to "lock" my file into a .stl or other similar format so that it would be impossible for someone to recieve the file and take measurements or work back to the original, individual .ipt's?

 

Thank you,

Bill

You don't tell us why you're providing the file in the first place.
If it's just for visualization, you can use dwf with markup and measure disabled.

I suspect the effort and results of trying to reverse engineer a dimensionally correct solid model from an stl would not be worthwhile for most people unless the geometry is really simple.  I do not know of an "easy button" software that would do this unless it is prismatic and cylindrical geometry, and even then there would be some interpolation.

 

Can you post a screen shot of the stl?

I'd rather not post a screenshot.  Basically, there are some critical dimensions that could be obtained from these models that would be very easy to measure and reproduce.  So if there is no way to keep the file in a format that prevents taking measurements then I suppose we just won't send these models out.

If the geometry is that simple, I think you will need to concentrate on being better, faster, cheaper at manufacturing as it will be copied from an actual part if there is a significant financial incentive to do so.  Being better, faster, cheaper removes the incentive to copy.

I didn't know you could disable the measurement that way. Got it now. Thank you.

Whoa, I don't know how to do that with a dwf file.  Drawing? or Assembly?

 

I just tried this in an assembly (*.iam) and got an error?

JD, I'm assuming you found these check boxes:

I get a popup when the dwf is opened but don't ever remember a crash.

I didn't say I get a crash.

 

I said I get an error trying to place a *.dwf file into a *.aim file (per the original problem description in post #1 (the pertinent portion of which I quoted)).

 

I think I was aware of all the settings in the images you attached - unless one of those settings allows for placing a dwf into an iam.

Yep, read error as crash.
I don't see where the OP says anything about what he wants the file for.
Can you open any dwf in IV except a marked up 2-D drawing?
