A problem after pocketing

[Mans]

These 2D profiles are not deleted after pocketing (even after I isolated them from that solid object), while in the images of the origin source ( it is a tutorial pdf) those sketches are eliminated after pocketing. What is the problem and how I can delete them?

when I delete them the pockets are deleted too.

Hide both sketches so you don't see them. Select them in the tree so you hide the entire sketch and not a line or curve inside the sketch.

Sketches are normally hidden (not deleted) after they are used to make a feature, unless the settings are modified to cause a different behavior.
