Methods, systems, and apparatus, including medium-encoded computer program products, for computer aided design and manufacture of physical structures using hybrid additive and subtractive manufacturing include, in one aspect, a method including: obtaining data for 3D geometry of a part; simulating at least a portion of a manufacturing process that includes adding first material in a first stage and removing second material in a second, subsequent stage, where the second material includes a portion of the first material, removing the second material includes blending between the material added in the first and second stages, and thermal effects of adding and removing the material in the first and second stages is simulated; and adjusting an amount of the portion based on results of the simulating to prevent deviation of the part from the three dimensional geometry that results in not enough material being available for the blending.
