John,
Are you doing these by hand or do you use the Autralian tool?
QCAD-LOGO consists of 125 lines… 
But thats nothing compared to YUKONRUBBLE.PAT, 4533 lines. e_surprised
Although, Qcad can’t handle that one.
Simply google ‘YUKONRUBBLE’ or ‘yukon rubble hatch pattern’.
This topic started before you proposed making custom hatches.
I made this one archaic to test my insight in and knowledge about hatches.
Turned out well.
About 48 lines was more than enough for me. 
Serves nothing as insulation hatches and others can be sourced freely from online.
Can you elaborated why LATTICE-04 is defined slanted at 26.57 degrees?
(The definition is with 26.565051 degrees)
Regards,
CVH
