When importing a file into SolidWorks 2017 or later, they may find working with imported files working differently. This is due to the 3D Interconnect option located under Tools->Options->Import->"Enable 3D Interconnect". As a visual way to see if a file was imported using 3D Interconnect, the files will have a slightly different icon in the feature tree with the green arrow pointing to the left:
As a brief summary of this option, it allows for the import of non-SolidWorks files while maintaining a parametric relation with them. As a result, the way that users interact with the files will be different.
Some of the typical workflows that won't be available when using the 3D Interconnect feature are:
-Opening up individual parts of the imported assemblies as a SolidWorks file
-Running Import Diagnostics
The reason for this is because since the files imported with 3D Interconnect do not actually create a SolidWorks file, there is no need for these workflows.
