Creo Composites trim option

Hi,

I am new to this Creo composites module, i would like to seek your help on few queries related to composites.

1. While we add multiple Ply on a model, how can we change the sequence when we are trimming the ply based on my requirements. Currently the ply sequence is opposite from my expectations. Attached image for your reference.

2. How do we understand what is wrong when we see the Drape status as can't able to drape in drape manager window? What should be corrected? how to analyze?

3. Can we manage the length of the ply manually? likewise while we apply the first ply we should be able to manage the length or key in the length value? is this possible?

Thanks
