Translations:Part and PartDesign/11/en

In the PartDesign WB the Body object represents a single solitary cumulative solid. The first lump created under the Body (be it a Pad from a sketch, or a BaseFeature from outside the Body) represents a lump of raw material that will be further processed to refine it to the desired final shape (solid). It is cumulative in the sense that each operation adds or removes material. The lowest/last operation (the current Tip of the Body) is the current state. Any other feature under the Body but above the Tip, does not represent a complete/stand alone solid. Only the Body (basically a proxy for the tip) or the Tip represent a complete solid.
