I have a SolidWorks assembly file and converted it to step format. When I open the step file in SolidWorks, only 1 part is opened.
The SolidWorks file has total 19 sub assemblies and parts combine.
I have already done a clean uninstall of SolidWorks 2015 and reinstall of SolidWorks but problem still exist. Also I disable KB 3072630 before reinstalling SolidWorks.
The problem does not happen on other assembly files.
