I'm getting an error message when trying to create a Sub-System
Cause: Frontline Scene is needed. Visit Importing your 3d model before creating a Sub-System.
I have dragged objects into the sub-systems "Device Elements" list, but can't select their children when testing the sub-system.
Cause: "Disable Children" option is turned on.
If this option is turned on, that tells the sub-system to treat the specific model you have in the "Device Elements" list as one part.
By turning it off, the user will be able to select all of the 'children' parts of the model while in the sub-system mode.
