1. A method, comprising: receiving, by a graphical editing tool of a computer, a command associated with a graphical editing operation directed to performing a transformation to a graphical object, wherein the transformation is associated with changing a value of a first parameter of the graphical object; displaying, by the graphical editing tool, a transformation object associated with the transformation, wherein the transformation object comprises a second parameter comprising a value associated with the transformation, and wherein the value of the first parameter of the graphical object is related to the value of the second parameter; receiving, by the graphical editing tool, an indication to convert the transformation object into a new parameter of the graphical object; converting, by the graphical editing tool, the transformation object into the new parameter of the graphical object; retaining, by the graphical editing tool, the converted transformation object during operations on other objects; and determining a function that defines the value of the first parameter based upon the value of the second parameter; wherein the new parameter comprises a derived parameter formed from expressions and/or functions that relate the derived parameter to one or more other parameters of the graphical object.
