The voronoi cutting problem

May I know why I cut voronoi and the model become like this?thanks

0505-cut vonoroi-25.dat (194 位元組) (776 位元組)

See here: What is the meaning of the wrong?
The voronoi only works reliably for convex shapes. You can break your dxf into two convex pieces, or else make one big block and cut it.
I also had to decrease the block size to get this to work reliably (12 seemed to work OK).

Ok,Thank you so much
