it's 'TechDraw' not 'tech draw'. Edited ticket.
I'll start a discussion for you on the forum.

Some of the overlapping vertical lines for the pins are being treated as "hard hidden" instead of "hard visible". Only part of the edge is hidden - does OCC not split the edge into visible and invisible portions before classifying??

is there a connection with 4564 short and/or overlapping lines not drawn??

using the perspective projector with a long focal length shows all the lines (also gives a better result for 4564).

this has come up before, but I can't find an upstream ticket.
