Customer defined linear/rotational motors in some assemblies. Some of the motors make parts move in the wrong direction when simulated in the Explode - Render - Animate environment (ERA).
Solution This is a known issue in Solid Edge ST10, which is resolved in the next release - Solid Edge 2019.
The workaround for ST10 is to set "Update" to "Relationships" in the ERA Timeline Editor.
