# OCCT 6.6.0: cutting 1600 cylinders from a box leads to out-of-memory on 32-bit system
#######################################################################

# test cutting box by many holes, inspired by
# http://www.opencascade.org/org/forum/thread_12369/?forum=3
# in OCCT 6.6.0 32-bit mode on Windows this fails with N >= 40 (out of memory)

# box plate to cut the holes from
box b 100 100 1

# N defines number of holes along each of X and Y, thus total N^2 holes
# will be drilled; note that the algorithm iself is likely to be quadratic
# for number of shapes, i.e. CPU ~ N^4
