Okay, I'm trying to do what you suggested, but the delete key does nothing. You're not talking about deleting the parameter name, are you? That's not what I was looking for. In the HierEditor, if I click on the wheel shaped icon next to the parameter, it highlights the parameter in white, but I cannot delete it. If I click on the parameter name it opens the naming dialogue and highlights it in black. I can delete this, but it leaves an unnamed wheel on the tool bar. DAZ's articulate props remove the wheel completely, which is what I'm looking for. Hope I'm explaining my problem well enough. I'm doing this on a machine with a low-memory videocard. After trying to delete a parameter when highlighted in white, it seems to lock up the Hierarchy menu and I cannot select anything further. I can close the menu, reopen it and select again, however. Perhaps if you explain your technique in a little more detail I can figure out if I need to switch machines, or whatever. :) Tilandra
