Details
The old assembly loads definition file created in NX6, when loaded in NX10 does not recognize all the paths in search folder and hence only partial assembly is loaded in NX.
Solution
The behavior occurs when the search folder list exceeds 256 characters.
This behavior was not reproducible in NX8 so a regression must have occurred in NX9 or 10, and it was ultimately fixed in NX12.
The only work-around in NX10.0 is to if we open the definition file in notepad++ and concatenate the file paths.
