Place MGED in the OBJ PICK state.
Figure (t1-obj-pk): Object Pick State
Figure (t1-obj-pk) shows what the display looks like when in the OBJ PICK state. As with the SOL PICK state, a single solid is selected. This solid becomes the reference solid for the object edit. In the OBJ PICK state, the solid will be shown as a member of one or more objects. Less obvious is the fact that the local axes associated with the selected solid are the axes used for the entire object during the object edit.
