I have a strange problem. For some strange reason i get after a while building on object always duplicated parts or faces and the are hidden. You spot them later.
Now i get the idea it happens when i do a duplicate and undo. Or it happens when i seperate parts later after a joing to correct something.
But i still not figured out how i always get duplicates without knowing. And am carefull but it happens still every build i think. It means you have lot’s of cleanup work later. and a change you still forget some.
Any idea’s ?
