Abstract
The invention concerns a method for the creation of addendums (4) of tools for sheet metal formed parts (2). In the case of this method, fill surfaces (7) for the smoothing of irregular zones of a component edge (3) are generated. Initial directions (31) of sectional profiles (10) are determined in such a manner, that sectional profiles (10) at a distance from one another are arranged along a component (3, 8) with utilization of these initial directions (31) and that an addendum (4) is creatable by the connection of these sectional profiles (10).
