Abstract:
1. Method implemented by a computer aided modelling system for creating a technical drawing of at least two 3D bodies that collide with one another, the technical drawing being used in the production of corresponding 3D objects, said method comprising the steps of: a) selectively determining one or more of the regions of the at least two 3D bodies that are affected by the collision; b) grouping of colliding faces of the selectively determined regions of the at least two 3D bodies to form a respective collision group; and c) generating a 2D model as the technical drawing of the at least two colliding modelled 3D bodies using parallel or central projection into a predetermined projection plane, wherein a 2D rim or its associated edge of a face that belongs to a collision group is treated with regard to visibility by masking the other faces that are associated with the same collision group.
