hello,

assuming that your reference to GRASS means this product:

<http://grass.itc.it/>


have you tried GRASP?

<http://trantor.bioc.columbia.edu/grasp/>


if GRASS was actually a typo for GRASP, and you are unhappy with its surfaces, well, I can't help.  I am under the impression that GRASP produces fairly decent surfaces.


I can't help wondering if I have confused everyone by now, or just myself.
