Abstract: The present invention relates to a method for determining a modified shape of a computer-aided design model of an object or a partition thereof, a method for assigning the modified shape of an object or the partition thereof to a further object or a partition thereof, a method for producing an object by applying any one of the indicated methods, and a module comprising at least one computer program being adapted for performing at least one step according to any one of the indicated methods.Herein, the method for determining a modified shape of a computer-aided design model of an object or a partition thereof comprises the following steps: (e) placing at least two reference landmarks at a reference position with respect to the shape of the object or to a partition thereof; (f) placing an adjustment landmark at the reference position of the corresponding reference landmark; (g) displacing any or all of the adjustment landmarks from the reference position to a modified position, whereby a displacement between the modified position and the reference position is obtained; and (h) generating the modified shape of the object or the partition thereof by modifying the shape of the object or the partition thereof by applying a homogenous function of the displacement to the computer-aided design model of the shape of the object or the partition thereof. Such methods are, especially, used in design optimization during product development in various industries, such as in automotive or aerospace industry, medical technology, or product design, in particular, to generate improved designs with regard to mechanical, physical, or aesthetic properties.

Abstract: A method of determining a modified shape of a computer-aided design model of an object or a partition thereof is described. With the method, at least two reference landmarks are placed at a reference position with respect to the shape of the object or to the partition. An adjustment landmark is placed at the reference position of the corresponding reference landmark. The adjustment landmarks are displaced from the reference position to a modified position, and a displacement between the modified position and the reference position is obtained. The modified shape of the object or the partition is generated by modifying the shape of the object or the partition by applying a homogeneous function of the displacement to the computer-aided design model of the shape of the object or the partition.
