@probuild said: what about the onClick? yeah, you can do that too using SET() in this case, i just added an onClick behavior to the parent then entered Set("door_vis",0,1) (and if you prefer, you can use TRUE or FALSE instead of 0 and 1) so now, in this example, the door can be hidden via the Component Options window's dropdown list OR with the onClick dc_parEx_withOnClick.skp
