1. A computer implemented method comprising:
running in a computer a modeling application that uses object instances to model one or more real-world articles, an object instance being defined by one or more object definitions; receiving, as a user input during modeling or when a model comprising one or more object instances is loaded, definitions defining at least one spatial modificator, definitions for a spatial modificator comprising at least its geometry information and location in the model, and at least one action definition; using the geometry information and the location of each spatial modificator to detect object instances that intersect with an influence area of the spatial modificator; changing, in response to detecting an intersecting object instance that intersects with the influence area of the spatial modificator, the intersecting object instance according to the at least the one action definition of the spatial modificator. |
