Expand description
Draft: turning faces about a neutral plane so a part can leave its mould.
A drafted face is the same face on a tilted support. It keeps the line where it crosses the neutral plane (that line does not move, which is what makes the draft measurable from a datum) and turns about it by the draft angle. Everything else follows: the neighbouring faces re-meet the tilted plane, the vertices re-solve, and the solid comes back with the same topology on new geometry.
That last part is not this module’s work. It is the offset’s rebuild, which already puts a solid back together on moved supports; a draft hands it turned surfaces instead of translated ones.
