Hi Matt, Sounds like a good idea. I was thinking it might be possible to do with a "setattr" or "sop" command, but unfortunately couldn't find such a solution. You can see from the mouseover help on the attribute inspector that it is a surface-piece attribute named lineThickness. If it were an attribute of the whole surface model instead, it would be possible to change it with "setattr M" (e.g. for the display attribute: setattr M display false). Tom is on vacation currently, but he may get back to you upon his return. Best, Elaine ----- Elaine C.

for the mesh adjustment, it would be good to be able to enter the radius of the mesh tubes. currently I have to select the item, go to the inspector to set the radius.
