Thanks for the reply.
That’s how I have done it but it looks unrealistic as I have a stack of parts floating in the air in effect.
I used a dummy component the same size as my stack components in the end to merge to and made it 0.1mm thick and transparent so you cant see it.
When I used the lowest part to merge to, it didn’t include it in the split so I was 1 part short and 1 left floating in the air. Maybe I didn’t use feed all so I will give that a try.
