Not only can I not auto-expode, I cannot save a manual explosion. The "save configuration" button gets greyed out. Anyone?
Edit: Figured out that you have to click the "display configurations" button, click the saved view, and then "update". Still haven't figured out the auto-explode problem though.
Edit 2: Actually you only have to click the "display configurations" button the FIRST time. Now I can continuously explode as much as I want and save because the button is ungreyed...
Is your assy imported model or assembled by you?
Auto explode doesn't work for imported assy, because it uses assy relationships between surfaces to define exploded direction, etc, but imported assy has no any relationships...
