I have an assembly where I use several Ipart components. I did a Pack-N-Go and moved these assemblies to a new directory. In the new directory I am able to launch the assembly IF I use the project file created in the Pack-N-Go command. When I use the PNG project file, I launch the assembly. Swap the Ipart "kid" with its parent Ipart and then back again. I offset a new workplane and delete it. Then I save the assembly. When I use the project file for the directory I sent the parts to Inventor is no longer able to Locate the Iparts. The Iparts are stored in the same directory as the assembly and the Ipart "kids" are in a subdirectory as named by the Ipart. Issue is the common project file will be used by my peers for future revisions. I expect this group has already covered the issues of Ipars and project files however my search through the discussion did not yield any resolutions. Any help would be appreciated!!!
