OK, I think the problem is that you'll need to export the mesh from Designer, modify it with another program (I use Blender) and then import it back into Pep for unfolding and resizing. I'm pretty stretched for time, but I'll have a go at taking the spikes off and removing the inside piece and putting it back into pdo format. Trouble is, it won't be for a day or so - pretty busy at school. Regards, Phil.
Actually doing that right now while on my break
