Abstract: In a modeling method and system, a model is created by using parametric basic elements and parameterized complementary elements, each having special parameters; such that a complementary object to be created with a parameterized complementary element is directly or indirectly, at least via one of its parameter values, associated with at least one basic object created with a basic element.

Abstract: Modification of a model in situations, where one end of several parts should be transferred for the same distance, for instance, has posed a problem in modeling systems. The problem can be solved by defining a magnetic control plane to which model part handles locating thereon will adhere without separate definitions given by the user and they move (406) along with the plane. The only thing the user needs to do is to create a plane and to define the plane type to be a magnetic control plane. On the basis of these data given by the user the modeling system knows what to transfer when the magnetic control plane is transferred.

Abstract: To minimize errors in computer-aided modeling, an object created by a user on the basis of a prototype must contain data about another object it can be linked with and about the linking. The object created by the user can be provide with these data by determining at least one logical property either for the object created by the user or for an object associated therewith; adding at least one logical definition to the object created by the user, the definition being based on at least one logical property of either the associated object or the created object; and forming a dependency by means of the logical definition.

Abstract: This invention relates to a method and systems to form structures from predefined elementary parts. In the invention at least two predefined elementary parts are combined for forming a desired structure. The part comprises desired features for the desired structure. A control means handles the combining of the elementary parts.
