the solidworks version is 2019 in Italian. I'm sorry to be ignorant, but I don't know what you mean by feature, maybe in the Italian version you'll say otherwise. I read the guide suggests to use copy entities from the sketch tool menu but allows me to copy inside a sketch and does it losing quotas while keeping the constraints. what if you use the normal ctrl c and ctrl v perfectly copy all quotas and constraints. The problem is that I want to copy from one sketch to another. I'm explaining I create a sketch that I call origin, in it I draw something that I quote and relatize. then I go out and want to have a copy of origin maybe to make small variations. on the tree there is no way to copy as you do with exploring resources. Perhaps I create a new sketch and name it destination and I go to paste what I copied originally but unfortunately I lose both quotas and constraints.
