The claimed subject matter includes a system and method to design 3D objects for fabrication. In embodiments, the method includes sampling coordinates of a two-dimensional object. The method also includes generating fabrication coordinates based on the sampled coordinates and a plane comprising a top layer of a three-dimensional (3D) object. Additionally, the method includes generating a 2D triangular mesh for the top layer of an overhang based on the sampled coordinates, an angle between the top layer and two points in a previous top layer border less than or equal to an overhang threshold angle.
