Shrinkwrap hacks???

[Anonymous]

It is my understanding that a shrimkwrapped part/assembly is similar to a "dummy" file in that it is design controlled and featues/tolerances are excluded.  We are in the process of converting from primarily ProE to Inventor 2011 release.  The engineers that have always used ProE claim that you can get past the shrinkwraped assemblies for use in reverse engineering our products.  In other words if I send out a shrinkwrapped assembly to a customer using real parts (not simplified files with no interrior geometry etc) the customer could somehow get the shrinkwrapped parts in the assembly to seperate and get the individual details or reverse engineer the assembly. 

I was brought up to believe that you should model with actual parts at all times and that shrinkwrapped assemblies were pretty safe to send out of the building.  The ProE engineers do not agree.  I send assemblies out as a composite using shrinkwrap, with no holes filled, no additional features included, and the link broken.

Does anyone have any information for me on this topic?

If you don't patch the holes then it will not remove internal details and it could be reverse engineered, yes the file is dumb at that point, but you can still get a ton of measurements off it to reverse engineer.  Shrinkwrap is the answer but you should examie your output to make sure you couldn't recreate it yourself as well.

If it is a composite it will not seperate out into individual parts though.  Try using reduced memory mode as well to remove nodes from the browser just in case.  This will also make the file smaller.

You need to patch those holes though.

Shrinkwrap is only supposed to have exposed faces, hence the name. The easy way to test this is to section the resulting part. If you can't find  internal faces, then customers can't dissect it to get components.
