Methods for computer-aided manufacturing and design, and corresponding systems and computer-readable mediums. A method includes receiving a three-dimensional (3D) solid part model and an associated 3D solid blank. The method includes defining an initial in-process workpiece (IPW) as the same as the 3D solid blank, and defining a cut volume in-process feature to be removed from the IPW. The method includes removing the cut volume in-process feature from the IPW. The method can include calculating and storing the cut volume in-process feature or the updated IPW with the removed cut volume in-process feature. The updated in-process workpiece can be calculated and displayed for each state at all times, in various embodiments.
