1. A method comprising:
modifying, by a computer aided design program, a three dimensional shape of a modeled object, for which a corresponding physical structure is to be created using a manufacturing process, to produce a modified three dimensional shape of the modeled object, wherein the modifying comprises, for each of two or more discrete layers of the three dimensional shape along a direction associated with the manufacturing process,
extracting a two dimensional profile representation of the three dimensional shape in a current discrete layer, the two dimensional profile representation lying in a plane that is perpendicular to the direction associated with the manufacturing process,
offsetting the two dimensional profile representation by an amount associated with the manufacturing process to form an offset two dimensional profile representation of the current discrete layer, and
changing a next discrete layer using the offset two dimensional profile representation of the current discrete layer; and
providing, by the computer aided design program, the modified three dimensional shape of the modeled object for use in manufacturing the physical structure using one or more computer-controlled manufacturing systems that employ the manufacturing process.
