Paste replaces selected object.
I realize this is a tradition in formz, but it causes me to lose more time than just about anything. The reason is that it is very easy to inadvertently select an object, move the scene so that it is out of view, and then paste an object I want to paste. Then later I notice that some object I've modeled is not longer there. Happens to me a lot.
In my opinion, this behavior should be a simple preference that can be on or off.
Thanks,
Donald
