Creating solid tapped holes

You can create holes in solids by specifying their use from a range of industry-standard hole types and sizes. Creating holes in this way also marks them as a solid feature; an operation applied to a solid, the details of which are stored and kept as a history in the solid feature tree. This is useful as solid features can be redefined, reordered, suppressed and deleted using the solid feature tree. You can also add chamfers to solid hole features, and mark the holes for machining in PowerMill.
