Hi.
In Capto, if we can lock object. But if we want to trace a second one over this one, even if it is locked, we can't ! Because we select the first one instead of creating a new one. This doesn't sound standard to me. Selection tool is for selection, objects tools are for creating. Of course it is very handy to "go back" to the selection mode after creating one object…
after, not before
Else, we have to trace in free space and then move the new object.
