hatch loops
hi , i 磛e one hatch object ( created with acad ) with 17 loops, 7 loops are inside another loop and 9 loops are seperate.
for the looptype flags i get only 3 with outermost flag and 14 without.
i expected 7 or 10 loops with the flag.
how can i detect which loop are inside another loop ?
depends the outermostflag one the loop order ?
the problems were inside the test data from another oda member application.
outer loops were marked with :utermost, holes with ::external.
what i磛e find out :
holes marked with :utermost
simple islands marked with :utermost | ::external
and islands with holes marked with ::external
