According to examples, a processor may place anchor points at determined locations of a digital model of an item to be fabricated by a threedimensional (3D) fabrication system. The anchor points may include points that remain in place during a placement determination of pores on the digital model and may correspond to locations at which pores are or are not to be formed in the digital model. The processor may determine places at which the pores are to be set in the digital model of the item, in which the pores are to be placed to comply with a predefined constraint with respect to each other and the anchor points and may modify the digital model to place the pores at the determined places in the digital model and to add pores at anchor points that correspond to pores in the digital model.
