OK, how about this?
x = randomu(seed, 20) * 20
y = randomu(seed, 20) * 20
z = randomu(seed, 20) * 20
d = dist(20)
isurface, d
id = itGetCurrent(tool=otool)
surfID = otool->findIdentifiers('*surface', /visualization)
result = otool->doSetProperty(surfID[0], 'Transparency', 50)
otool->refreshCurrentWindow
iplot, x, y, z, /overplot
sendToBackID = otool->findIdentifiers('*sendtoback', /operations)
result = otool->doAction(sendToBackID)
