Detailed Description

The injector plate read from its revolve sketch (engine/core/injectors/plate_dxf.py).

The synthetic plate is built from a chosen answer -- exits, passage lengths, facets normal to
the passages, a flat-bottomed groove -- and the reader must recover that answer from the lines
alone. The shipped drawing is checked against numbers worked by hand from its coordinates.
