I read this sentence in a 3D grips skill builder:
Solved! Go to Solution.
Solved by jdkriek. Go to Solution.
For the type of example you are using...
Note: It has to be a individual feature that could be moved to the face you select.
Click the grip arrow, release mouse, click the face (should move if it can), release, right-click and choose Done.
Is this a part you created or a sample?
The reason I ask is because the method they are talking about is with two features. If the entire body is one feature (all wireframe in grip mode) you could click grips and drag, but you won't be able to move it to another face on that feature.
