Computer-implemented method for changing a model geometry of an object

A computer-implemented method for modifying a model geometry of an object, wherein the model geometry can be used to produce the object, the method comprising the following steps:

• providing a target geometry for the object;
• providing a model geometry for the object;
• using the model geometry to provide an actual geometry of the object;
• determining whether there is at least one deviation present between the target geometry and the actual geometry;
• and
• changing the model geometry into a modified model geometry based on the determined at least one deviation, if at least one deviation is present;
• wherein at least the step of determining, if at least one deviation is present, results in a first non-rigid mapping, the first non-rigid mapping associating two geometries with each other by means of a parameter set and describing the determined at least one deviation, or at least the step of changing is carried out by means of a second non-rigid mapping, the second non-rigid mapping associating two geometries to each other by means of a parameter set.
