Hello. How can I describe the opposite operation of this: "to fix the vertices of object A (to somewhere)" ? The image of what I want to describe is like "to release the vertices", "to cancel fixing", or "to return the fixed vertices to non-fixed vertices" but I'm not sure whether these expressions are natural or not. I am afraid the question is technical, because the expression was found in a manual of 3D editing software, in which I couldn't find any good antonym of "fix" in this meaning. Thanks in advance.
