Shrinkwrap Add-in for Inventor enables users to quickly create a single part by removing all internal content from an assembly. New Shrinkwrap parts can be delivered with confidence to external consumers because the internal details can’t be uncovered. Users’ proprietary design information will stay confidential. Also, a Shrinkwrap part consumes substantially less memory compared to the fully detailed assembly.
