Thanks, Mike. That is just what I needed. Much appreciated.

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)

There are "Order > Bring to Front" and "Order > Send to Back" context
menu items for graphics items in the iTools that will do the trick. Let
me check if there is a programmatic way to access them.
