Having problems with the symmetry functions on designer. Sometimes the 4 buttons light up in the Edit box for certain parts that are highlighted and don't for others. My main issue is whether the buttons are lit or not, items are duplicated when adding them to hull, like engines, armament, etc. with no way to remove without removing the first placement also. I often try and place another similar item on the duplicate and this works most of the time, but too often it takes the patience of a rock to make the exact connection. Can someone give me some tips on how to master this devilish design function? How do I keep parts from being symmetrically placed even when the symmetry buttons (4) are greyed out? Also what causes the functionality of the symmetry buttons to turn on originally. I'm at a loss and the few UTube how to's don't really cover it, or at least I haven't found one yet. Frustrated in Florida...
