Aldo ZarateandClaude Opus 5.5 d19df49fcf HATCH and LWPOLYLINE in a tilted plane are read as seen from above (#1886)
Their boundary and vertices are in the object's plane (OCS). Only a
mirrored plane (0,0,-1) was handled, by flipping x; a tilted plane whose
normal points down was taken for a mirror too, and one pointing up kept
its plane coordinates, so each face landed turned about the origin by
its own angle. A tilted one is now mapped to the WCS and drawn as seen
from above at its mean height: bulged edges are flattened (they are
elliptical there), and a hatch's pattern direction and origin follow.
Its extrusion becomes Z, since its points are plan coordinates now.
