Cryovac

Hi there,

I've still got my training wheels on this...  I've been trying to learn kangaroo and was looking at someones drape expression that was posted on this. 

I am wanting to use roo to cover some spheres (located at vertice of cube) in a surface and slightly cryovac in the surface so they wrap around the spheres and pull in. Ideally kangaroo can just change the negative pressure to cryovac about the spheres tighter. The spheres are located at the vertices of a cube so it's not a simple drape.. the fabric needs to be sucked in from the centre of the cube.

i've attached the files which might be easier to see what i'm trying to explain.

thanks a million for any help, i'd really appreciate it
