Structs

OffsetSurface

Copies the faces named faces — of a solid or standing on their own — distance along their normals, against them for a negative distance, into a sheet of their own, for the operation O: where faces meet, their copies meet where the offsets of their surfaces do. The faces stay as they are; the copy of each face, edge and vertex X is offset(O,X).
