Duplicate features

[[Da...]]

Good morning, everyone. Why, when I use the copy command to copy the characteristics of an element, does it duplicate them? Thank you very much.

[[No...]]

You can insert copied elements with or without references (see context menu). With references also duplicates dependent elements. But I'm not sure if it works in both directions ("copy feature -> also copy characteristic" vs. "copy characteristic -> also copy feature")

Sorry, I mean that the features are duplicated when I use the copy and paste formatting icon between several items.

you can duplicate a caracteristic on several feature, or copy datum, strategy... from one features to the other, but I don't see how you can duplicate feature.
