View real-time volume in Rhino (with grasshopper GECO) in ECOTEC (2011)

hello, I ask you to know how to make a volume (mesh) can see it in real time on ECOTEC (2011) in order to evaluate the program. I have tried using GECO, but do not understand how to configure it while changing the geometry (with grasshopper) can see and analyze in ECOTEC.
* Is the volume generated at the intersection of the cube to the sphere
Greetings and eternally grateful to anyone who can answer!

PD. ATTACHED FILES

    you have to re - export the mesh each time. there should be an answer to this at the geco page.
