Hi,
You could edit the profile of the sketch/profile. Select everything (Ctrl+A). Click the 'copy' button. Then create a new feature or sketch, choose a plane and then click the 'paste' button. Reconstraint that profile to the reference planes if necessary.
Otherwise, you can copy/paste features from the edgebar (not sketches though...). It can be one feature or a group of features. They can be pasted in that same part or another one or even in the 'feature library' tab of the edgebar for reuse later.
In Solid Edge, if you want to create a sketch that can be used by many features (integrally or partially), you need to use the command 'sketch'. Later, when you want to use that sketch, use 'select from sketch' in the first step. (careful, for revolved features, the sketch must contain a drawn axis of revolution).
A sketch can also be copied onto another plane using the 'tear-off sketch' command (associatively or not).
If a sketch is embedded in a feature (ie drawn during the 2nd step of a protrusion or cutout), it is then called a 'profile' and cannot be pulled out of the feature. Fot that reason, it is recommended for beginners and/or complex features to start with independant sketches ('sketch' command) and after start the protrusions/cutouts using the option 'select from sketch' (above the different types of planes). Hint: Roll the scroll on your mouse to go to the top of that list quickly.
HTH,
Fred
