I'm currently using SolidWorks Electrical to and I have a project with multiple locations that contains multiple panels. I'm designing each of my panels at the different locations. On the 3D side sometimes the electrical manager disappears, making it impossible for me to continue with my project design. This only occurs fro some of my locations (assemblies) and sometime it appears but on rebooting my machine it disappears. What can be done to resolve this issue?
